AB  - The impacts of nano-silica addition, steel micro-reinforcement, and aggregate type on the mechanical properties and durability of ultra-high-performance concrete (UHPC) were studied. As aggregates, quartz and barite were used. The amounts of steel fibers and nano-silica were alternated. Six concrete mixes were produced with quartz sand, and the remaining six concrete mixes were designed with barite sand. Fibers made about 3-5% of the concrete composition’s mass. In a 2-5% concentration, nano-silica was used as a cement replacement. The inclusion of nano-silica significantly boosted the compressive strength of UHPC. The compressive and flexural strengths were also positively impacted by fiber supplementation ranging from 3% to 5%. The amount of fiber utilized proved to be more influential than the aggregate used. The UHPC concrete's durability was increased as all samples were highly resistant to freezing and thawing cycles. UHPC designed with barite aggregate demonstrated good X and gamma ray absorption at energies below 300 keV.

AB  - The chemical compositions of refractory materials, such as high-alumina concrete, bricks, and putty, were analyzed using an energy-dispersive X-ray spectrometer (EDXRF). An improved methodology for investigating the effect of particle size on the outcomes of EDXRF chemical analysis is presented. Eight independent refractory samples (refractory concrete, brick, and putty) were pulverized utilizing seven milling times (30, 60, 120, 180, 240, 300, and 360 s) and compared to non-pulverized samples. Thus, sixty-four refractory samples were obtained and analyzed using EDXRF. The method for measuring the fundamental EDXRF characteristics was then tested with ten certified reference materials. The acquired data were compared using inductively coupled plasma atomic emission spectrometry (ICP-OES). Univariate and multivariate statistics are used to evaluate EDXRF data. The particle size of the tested samples affected the z-scores of SiO2, Al2O3, Fe2O3, TiO2, CaO, MgO, Na2O, K2O, and P2O5 concentration measurements. Grinding times for refractory concrete, brick, and putty samples were determined in order to validate the robustness of the EDXRF technique and provide reliable chemical analyses. The ideal milling times for the samples studied ranged from 180 to 360 s, depending on the type of refractory material.

AB  - Finding a solution to the problem of the large buildup of coal ashes is a vital necessity. Although the use of coal
ashes in fired clay bricks has been thoroughly investigated, there is insuffcient information on their industrial
utilization and researchers do not agree on whether or not this addition improves the quality of the fnal
products. Therefore, a database has gathered 20 years of research containing key factors related to the quality of
the bricks (i.e., chemical composition, fring temperature, soaking time, open porosity, water absorption and
compressive strength). Then, random forest regression and artifcial neural networks (ANN) modeling were used
to separately predict the parameters concerning the quality of the fnal products. The overall conclusions were
that the compressive strengths were the highest when using fly ashes and that class F ashes were highly suitable
to be used in the brick industry as a replacement material for brick clay. In addition, the ANN models showed
higher coeffcients of determination and an overall better fit to the experimental data. By changing the chemical
makeup of the initial materials and their proportions, the particle size of the ashes, the firing temperature and
soaking time, as well as the size of a product, the created models can be used to estimate the quality of the brick
containing coal ash. That is crucial because the inconsistent chemical composition of ash is generally the main
obstacle to its utilization. The local sensitivity analysis revealed the highest influence of the content of the alkali
oxides in the initial clay on the fired clay bricks due to their fluxing effect. In the case of ash-clay bricks, the
decisive factors were the type of furnace used, the ashes’ class, the Na2O content in raw clay, and the K2O
introduced with the ash. The F class ashes containing about 2–3% of K2O and <5% of CaO gave the highest
compressive strength in bricks fred at 1000–1100 ◦C.
Additional analyzes were made for 50% pond ash and 50% clay bricks to test the best-suited model and fill in
the knowledge gap. The results obtained in this study are important for supporting the decision in the selection of
materials and process parameter values that will increase the quality of the ash-clay-fired bricks.

AB  - Natural zeolite and bentonite were used as mineral addi-tions to create cement-based building materials that are safe for the environment. This research focuses on the adsorptive qualities of these two clay raw materials, i.e., their propen-sity to immobilize heavy metal ions like Cd2+. The acquired results were examined using kinetic models of pseudo-first and pseudo-second order. The isotherms of Langmuir and Freundlich were examined. Zeolite and bentonite had differ-ent adsorption affinities for Cd2+ cations. Seven cement binders with various mineral additions (fly ash, zeolite, bentonite) underwent a leaching test. The adsorption and hydration mechanisms that immobilized heavy metals within cementitious composites caused leachates obtained on cement samples with the addition of fly ash and clay (either zeolite or bentonite) to contain lower concentrations of Cd2+ ions than leachates obtained on cement samples with fly ash alone.

AB  - During the last few decades, the requirements for modern machine elements in terms of size
reduction, increasing the energy efficiency, and a higher load capacity of standard and non-standard
gears have been very prevalent issues. Within these demands, the main goals are the optimization
of the gears’ tooth profiles, as well as the investigation of new tooth profile designs. The presented
design idea is based on the optimal solutions inspired by nature. Special attention is paid to the new
design of the tooth root zones of spur gears in order to decrease the stress concentration values and
increase the tooth root fatigue resistance. The finite element method is used for stress and strain
state calculations, and the particular gear pair is modeled and optimized for these purposes. For
tooth root strength analysis, the estimations are based on the theory of critical distances and the
stress gradients obtained through finite element analysis. The obtained stress gradients have shown
important improvements in the stress distribution in the transition zone optimized by biomimetics.
An analysis of the material variation influence is also performed. Based on the investigations of a
particular gear pair, a significant stress reduction of about 7% for steel gears and about 10.3% for cast iron gears is obtained for tooth roots optimized by bio-inspired design.

AB  - The experimental study included the design and production of ultra-high-performance steel fiber-reinforced concrete (UHPFRC). The physical and mechanical properties of UHPFRC were investigated in a laboratory setting. To investigate the properties of UHPFR concrete, three types of concrete and over 70 samples were used. Following that, samples were created to test the anchors' load-bearing performance. Six concrete slabs with a total of 108 pre-installed anchor samples and six concrete slabs with 108 post-installed chemical anchor samples were created. The analysis of the test findings comprised all individual results as well as the definition of the relationship between the anchor's tensile load capacity and other parameters. To accurately determine the individual influence of the investigated factors as well as their combined impact, a factorial experiment, and artificial neural networks were used in addition to normal statistical numerical studies. It was determined that both approaches offer advantages. The results obtained show matches in certain parts. Due to the way data is processed in different ways, there are also significant differences between them.

Six concrete slabs with a total of 108 pre-installed anchor samples and six concrete slabs with 108 post-installed chemical anchor samples were created. The analysis of the test findings comprised all individual results as well as the definition of the relationship between the anchor's tensile load capacity and other parameters. To accurately determine the individual influence of the investigated factors as well as their combined impact, a factorial experiment, and artificial neural networks were used in addition to normal statistical numerical studies. It was determined that both approaches offer advantages. The results obtained show matches in certain parts. Due to the way data is processed in different ways, there are also significant differences between them.",

AB  - Compared to traditional concrete, self-compacting concrete (SCC) demonstrates greater flowability, which is achieved by including an extra high percentage of ultra-fine particles. As a result, the required high paste content is obtained while the cement content is strictly limited. The coal combustion byproduct (fly ash) is one of the most efficient SCC fillers because it extends the lifecycle of SCC by improving its microstructural properties, strength, and durability. In this study, the amounts of fly ash in SCC compositions varied. The changes in physical and mechanical characteristics of fresh SCC samples related to variations in the water/binder ratio were monitored.

AB  - Even though the specific COVID-19 consequences for sales have been extensively
discussed, no academic research has been done on how the pandemic has affected
consumer choice and purchases of construction and building products by private
individuals. This research was conducted to fill in the gaps in the body of knowledge
and advance understanding of how the crisis has impacted wages, market prices,
and material usage in the construction industry in a developing country. The data
are collected through the use of a questionnaire survey. The respondents shared
their experiences between the period before 2020 and after the beginning of the
crisis up until the end of 2022 and showed that purchases of these products
decreased during the lockdown and afterward. The obtained results were analyzed
using statistical tools, namely frequencies, descriptive statistics, and constructs.
This study reveals a high interest in using novel materials but also a desire to be
more informed on the details and their potential benefits. The results present a first of-
a-kind approach that will help further development in this branch of the industry
by following the needs of potential private customers in a developing country.
Further studies would need to include not only contextual but also personal factors
that influence environmentally friendly choices.

AB  - Over the past few decades, the fired clay brick industry has searched for industrial wastes to substitute raw clay deposits and lessen their impact on the environment. Despite several investigations showing positive results, industrial applicability is still scarce, mainly due to differences between industrial and laboratory procedures and the usage of certain wastes that already have added value in other circular economy chains. In addition, the assessment of such proposals commonly misses the environmental impact issue which is merely assumed to be positive. For these reasons this study, for the first time, has assessed together technological properties and the environmental impact of bricks made by strictly following industrial procedures. Hence, biomass bottom ash (BBA) was added at 9 replacement ratios, ranging from 2.5 to wt. 20.0% for making extruded bricks subjected to industrial drying and firing curves. Physical, thermal and mechanical properties of fired products were properly assessed and compared with the requirements set forth by Chilean standards. In addition, a life cycle impact assessment was developed to compare the ecological footprint among series. Although mechanical and water-proof requirements may limit the replacement ratio for exposed bricks, the feasibility of using BBA at industrial scale has been successfully demonstrated. Regarding the environmental impact, the raw clay may be replaced without adversely causing toxicity levels to exceed mandatory limits. However, this study demonstrated that the incorporation of BBA increases CO2 emissions due to the decomposition of contained carbonates during the firing process which compromise the results in terms of global warming potential and water consumption which highly impact on human health and ecosystems quality.

AB  - The present study analyses the usage possibility of the 7
raw kaolinitic clays from Serbia. The characterization of
raw materials is done by using instrumental techniques to
determine chemical and mineralogical compositions, particle
size distribution and behavior during firing (changes in
mass, temperature of the system and dimensions). Additionally,
refractoriness is determined for each of the materials.
The samples are shaped by the extrusion process and fired
in a 1000-1250 °C range. The ceramic and technological
characteristics of the fired samples are determined, and
micromorphology is recorded. It is concluded that most of
the tested clays can be used to produce cream-colored
extruded ceramic tiles with water absorption between 0.20
and 5.28 % by firing at 1250 °C. The majority of the samples
can be used as ceramic tiles for flooring purposes after
firing at 1200 °C. Additionally, all samples are found suitable
for special purpose roofing tiles production after firing
at 1100 °C.

AB  - Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, making it a suitable mineral additive for refractory non-shaped materials and various ceramic shaped products. In this study, pyrophyllite is employed as 50 % clay replacement in the ceramics and up to 30 % cement replacement in mortars. Physico-mechanical properties were investigated. The firing shrinkage in the ceramics treated at 1200°C was reduced by pyrophyllite addition. Pyrophyllite acted as additional pozzolana during cement hydration. Within the microstructure, it formed micro-reinforcement in the shape of crystalline folia, which improves the mechanical properties of ordinary Portland cement, high aluminate cement, and blended cement mortars. The investigation proved the efficiency and suitability of pyrophyllite employed as a substitution for clay in ceramics and a cement replacement in mortars.

AB  - The paper shows the comparative analysis of behavior and bearing capacity of piles examined using the Dynamic Load Test (DLT) according to Static Load Test (SLT) results. The pile testing methodology is based on the existing ASTM standards and experiences of the authors of the paper. The pile tests were carried out using counterweights, reactive system, dynamic testing equipment, hardware and software for SLT and DLT. The data obtained by testing were statis-tically processed, and also a regression analysis of the linear function was conducted, resulting in the creation of the model for the change of mobilized static bearing capacity from DLT according to SLT. In addition, a procedure for correcting the solution of mobilized static bearing capacity from DLT according to SLT, is made by observing provisions of standard EN 1997-1:2004, so the average deviation of solutions from DLT according to SLT is reduced. Apart from that, through iterations, the value of correlation factor ξ5 is determined, taking into consideration solutions presented by SLT and DLT of piles of the real structures.

AB  - The application of dispersive soil can result in various types of damage, and even the collapse of embanked build-ings if it is not identified. Dispersive soils cannot be uniquely identified by visual identification in the field, or by usual standard methods used for soil identification in the geo-mechanical laboratory. The paper presents the results of laboratory geomechanical tests aimed at identifying and classifying erodible dispersive fine-grained soil. The tests were carried out using the crumb test, the double hydrometer test (SCS), and the pinhole test on samples: sandy clay embankment dams of ‘Rovni’, loess from different locations (Zemun, Novi Beograd, Titel, Kelebija, Srbobran, Slanka-men, Ruma, Mali Iđoš) and kaolinite sandy clay deposits Grabež - Aranđelovac. The possibility of improving disper-sive soil by adding fly ash was also analyzed. Pinhole tests on dispersive soil samples with the addition of 10, 30 and 50 % ash showed that there was a decrease in dispersivity of natural soil for one to two dispersion classes.

The results of impact tests for all three constituents of the manual arc welded joint of NN-70 steel at temperatures range from 20 °C to -100 °C are presented. It has been shown that impact tests of high-strength low-alloy (HSLA) steels at room and lower tem-peratures indicate that temperature significantly affects the toughness of high-strength low-alloy steels in the context that lowering the test temperature leads to creation of brittle fracture in the form of a successive decrease in total impact energy. This indicator is very important in the further design and exploitation of welded steel structures.

The Artificial Neural Network (ANN) prognosis of mortar behavior was conducted in this study. The model appraised the design and characteristics of seventeen either building or high-temperature mortars. Seven different cement types were employed. Seventeen mineral additives of primary and secondary origin were embedded in the mortar mixtures. Cluster Analysis and Principal Component Analysis designated groups of similar mortars assigning them a specific purpose based on monitored characteristics. ANN foresaw the quality of designed mortars. The impact of implemented raw materials on the mortar quality was assessed and evaluated. ANN outputs highlighted the high suitability level of anticipation, i.e., 0.999 during the training period, which is regarded appropriate enough to correctly predict the observed outputs in a wide range of processing parameters. Due to the high predictive accuracy, ANN can replace or be used in combination with standard destructive tests thereby saving the construction industry time, resources, and capital. Good performances of altered cement mortars are positive sign for widening of economical mineral additives application in building materials and making progress towards achieved carbon neutrality by reducing its emission.

AB  - In order to rate the drying behavior of different clay raw materials it is necessary to establish
the criteria for comparison. Mineralogical composition, clay minerals content, particle size
distribution, packing, porosity, forming procedure, and raw material aging are known as
intrinsic parameters. Due to the fact that these parameters are cross linked and are usually
inter-dependently related to each other, the attempts to set up a criteria for correlation between
intrinsic parameters and drying sensitivity has been limited. That was the reason why the
estimation of the cracking tendency was linked with the easiness of the drying process in each
reported method. The most applied methods for estimation of the drying sensitivity of clays in
the ceramic industry were proposed by Bigot, Ratzenberger, Piltz, Hermansson and Varlamov.
The fact that previously mentioned methods were not compared up till know has defined the
main objective of this study. The only reported comparison was between Bigot and Ratzenberg
drying sensitivity index. The second objective of this review was to present these methods and to
estimate the drying behavior of tree different clay raw material. It was confirmed that Varlamov
method is very simple, accurate and fast. It is correlated with the mineralogical composition of
clay and cannot be used for description of the drying kinetic. The other two models can provide
info about the drying kinetic. Piltz model is the most relevant for describing the drying behavior at
the beginning of the drying. The results have confirmed that the most suitable conclusion about
the drying behavior of the tested clays is obtained when results from Bigot, Piltz and Varlamov
methods are available.

AB  - This paper goal was to increase the quality of the drying ware and to lower the drying scarp rate in one local brick factory. The registration of drying air parameters (temperature, humidity and velocity) along the dryer channels as well as the drying ware linear shrinkage and mass change were monitored for a month. Material and Energy balances were also recorded. Results have revealed that the drying air humidity and temperature profiles were not evenly distributed along the height of the drying tunnels. The ambient air breakthrough into the dryer was experimentally identified and quantified. It was the cause of the product quality deterioration and the reason why the critical and residual moisture in some of the products was larger than the desired one. Based on monitored data and mass and energy balances a solution was proposed for preventing the “false” air breakthrough, upgrade of the existing dryer fans and installation of the novel, measuring equipment. A hypothetical solution for increasing the capacity of the dryer, which uses the registered material and energy balances as well as factory management expectation, that the production of 50.000 masonry units per day will be achieved soon, was given also.

AB  - In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such as loose powder, pressed pellet, and fired pressed pellet. The fired pressed pellet approach was observed as a part of universal sample preparation for physic, mechanical, and instrumental analysis, which has not been previously tested as a solution in chemical analysis by the EDXRF method. The observed sample preparation techniques were compared by calculating the parameters of validation (recoveries, limit of detection-LOD, limit of quantification - LOQ, precision, and expanded uncertainties of measurements) of 11 elements (Si, Al, Fe, Ca, Mg, K, Na, Ti, P, Mn, and S) using 15 certified reference materials (CRMs). Calibration curves were created and evaluated using 30 reference materials (RM) for all three approaches. Results proved that the fired pressed pellet is the most practical and precise approach for sample preparation of raw clays.

AB  - One of the significant problems in the production of ceramic tiles is the very high consump-tion of natural resources such as clay, feldspar, and quartz. The possibility of replacing part of the formulation of ceramic batches is of great importance. In this research, the possibility of using aplitic granite waste from dimensional stone production was analyzed in detail. The waste is considered a low-cost substitute for feldspar in Serbia. The milled powdery waste was analytically tested to reveal its chemical and mineralogical contents, particle size distribution, and other important properties. The ceramic tiles containing aplitic granite waste (GW) and GW/raw clay mixture (CGW) were hydraulically pressed, and the ceramic and technological properties determined. This waste can act as a filler while forming, drying, and firing, since the high content of quartz helps to control the shrinkage and acts as a fluxing agent in high temperatures due to its feldspathic nature. The waste was found favorable in the production of ceramic tiles, as the gained values of modulus of rupture and water absorption were 28.68 MPa and 1.33%, respectively. The parameters defined in the series of standards EN ISO 10545 were tested on a semi-industrial probe, determining that this combination of materials (without the addition of quartz) may be efficiently used to produce ceramic floor tiles. The usage of what would otherwise be waste material contributes to sustainable management and environmentally friendly solutions by avoiding landfilling, while at the same time it enabling the conservation of scarce natural feldspar deposits.

AB  - The Guarded hot plate method (GHP) is a widely used technique to measure thermal conductivity of thermal insulation specimens in steady-state conditions. In this paper, an advance of GHP has been developed in the Laboratory for Thermal technique and fire protection in Institute IMS. The innovative GHP has been applied for measuring thermal conductivity using additional heat flux meters. The design of this GHP is similar to the design of the plate for GHP apparatus; however, it has different design: smaller width of thermal barrier, which is filled with insulation glue. Heaters inside hot and guard plates are built from wire for thermocouples, which is a unique type of heater. Geometry of heater has been optimized inside plates to achieve uniform temperature distribution along the specimen surface. Temperature uniformity of guarded hot plate and energy balance were experimentally determined. The verification and validation results of improved GHP have been shown. The test method was validated comparing test results of thermal conductivity with results of the round-robin test. Four national companies participated in the round-robin comparison on thermal conductivity measurement by guarded hot plate method. The measurement was performed on the same specimen of thermal insulation material (expanded polystyrene) according to SRPS EN 12667 at temperatures ranging between 10℃-40℃. The measured thermal conductivity of all participants in the round-robin test was input data for statistical processing according to SRPS ISO 5725-2 and ISO 13528. To evaluate the performance of the participants, the “z” score has been used. Measurements were conducted successively for all participants. Since 2020, the Accreditation Body of Serbia also approved this test method.

AB  - To reduce occurrence of fires in buildings as efficiently as possible, it is necessary to take into account active and passive fire protection measures during construction of building. This paper will show more about passive fire protection measures related to the selection of adequate material to be used during construction, which contributes to the localization of fire and prevents it from spreading to other rooms and facilities.
All products, which are planned by project, must have adequate certificates not to contribute to the development of fire, as well as to meet the class of fire resistance. In the Republic of Serbia, only the Laboratory for Thermal Engineering and Fire Protection, within the IMS Institute, deals with this type of testing and issuing reports.
This paper will present test methods for obtaining a fire reaction class. After the tests, according to the standard SRPS EN 13501-1, a Classification Report is issued in which the final fire reaction class is given for the tested product whose validity lasts for 5 years.
