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.

AB  - The machine learning technique for prediction and optimization of building material performances became an essential feature in the contemporary civil engineering. 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  - 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.

abstract = "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  - 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 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.

AB  - Testing the clay hollow-brick masonry non-load-bearing wall helps us to understand the behaviour of this type of wall during a fire. It is important to know the fire resistance of hollow brick walls so that we can prevent the fire from spreading to other rooms. In this paper, the experimental analysis of fire resistance of non-load-bearing wall with dimensions 3000 mm x 3000 mm thickness 200 mm were presented. The wall was made from clay hollow-brick masonry blocks with dimensions 500 mm x 200 mm x 249 mm (L x D x H) with mortar on both side of wall of thickness 15 mm. The wall was exposed to a standard fire test according to SRPS EN 1363-1:2014. The temperatures on the unexposed side of the wall were measured in thirteen positions with thermocouples (K – type) according to the national standard SRPS EN 1364-1: 2014, and at the junction between mortar and clay hollow-brick. Deflection of the wall in five places was measured also. Obtained results depending on the time of reaching the critical temperature during the fire test were presented.

AB  - The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Greeds Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature distribution is evaluated in the general form and expressed in the terms of the convolution integrals. The GF are employed in the novel approach for calculation of Thermal Response Factors (TRF) with arbitrary shape functions for unsteady heat conduction in composite planar structure. The two pairs of TRF for spatial and temporal distribution of the temperature and the thermal flux are obtained. The whole analysis is performed in the time domain. A numerical scheme for efficient evaluation of convolution integral suitable for practical application in the case of the long term measurements with lower sampling rates is developed. The in-situ measurements of inside and outside surface temperatures and outside heat flux for a building wall under real dynamical environmental conditions during the period of then days are used for validation of the presented results and to demonstrate the possible practical application. Using developed approach and recorded surface temperatures as inputs the temporal and spatial distributions of the temperature and the thermal flux are obtained. These results are compared with experimental data and numerical simulations obtained by the Finite Volume Method (FVM).

The analytical solution for spatial and temporal temperature distribution is evaluated in the general form and expressed in the terms of the convolution integrals. The GF are employed in the novel approach for calculation of Thermal Response Factors (TRF) with arbitrary shape functions for unsteady heat conduction in composite planar structure. The two pairs of TRF for spatial and temporal distribution of the temperature and the thermal flux are obtained. The whole analysis is performed in the time domain. A numerical scheme for efficient evaluation of convolution integral suitable for practical application in the case of the long term measurements with lower sampling rates is developed. The in-situ measurements of inside and outside surface temperatures and outside heat flux for a building wall under real dynamical environmental conditions during the period of then days are used for validation of the presented results and to demonstrate the possible practical application. Using developed approach and recorded surface temperatures as inputs the temporal and spatial distributions of the temperature and the thermal flux are obtained. These results are compared with experimental data and numerical simulations obtained by the Finite Volume Method (FVM).",

AB  - In this paper a comparative analysis of thermal behavior of six partition walls with different
thicknesses were presented. The walls were dimensions 3000 mm x 3000 mm made from autoclaved
aerated concrete blocks with dimensions 625 mm x 200 mm and thicknesses 50 mm, 75 mm, 100 mm,
120 mm, 150 mm and 250 mm. All walls were exposed to standard fire test according the standard
SRPS EN 834-1, non- combustibility test according the standard SRPS EN 1182 and surface spread of
flame test according to SRPS U.J1.060. All walls were tested to fire resistance in vertical furnace with
a data acquisition system, according to standard fire test. Standard furnace for testing construction
consist of four two step burners in liquid fuel type of 296
kW manufactured by ECO FLAM. Two transmitters of differential pressure type 6321 manufactured
by TESTO (Germany), with range 100 Pa installed inside the furnace were used for pressure
measurement. Inside the furnace the temperature on six places with thermocouple type K were
measures. The measure ranges of thermocouple type K were -2700C to 13720C. The temperatures on
unexposed fire side were measured in nine places with thermocouple type T with measure ranges -
2700C to 4000C of according the national standard SRPS U.J1.090. The obtained temperature results
depending of the time of reaching the critical temperature were presented for each wall thicknesses.
The five identical cylindrical samples with high 50 mm and diameter 45 mm for non-combustibility
test has been used. All samples have been tested in standard furnace for non-combustibility test. The
average temperature in furnace and specimens were presented. Surface spread of flame testing is
carried out according to standard SRPS U.J1.060, if the coating material is based on organic or mixed
materials. The samples for these test are with dimensions 900 x 230 mm.

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 European Green Deal, which emphasizes zero-waste economies, and waste recycling
in construction and building materials, has arisen due to significant worldwide needs for solid waste recovery and usage. This ambitious study focuses on recycling mixed construction and demolition (C&D) waste into burnt bricks and investigating the influence of firing temperature. While pursuing its objectives, this is dependent on raw material characterization and burnt-brick product quality assessment. The recycling of mixed C&D waste is explored by mixing the waste into two soil types (alluvial and laterite) in ratios ranging from 5% to 45% at three firing temperatures (700 °C, 850 °C and 900 °C). The utilization of mixed C&D waste in amounts of 10% at 700 °C and 25% at 850 °C and 900 °C fulfilled the Indian standard. Although a fire at 700 °C results in less optimal waste utilization, it is beneficial and recommended for reducing the carbon footprint and energy use. Additional mineralogical and microstructural analyzes are performed on the optimal fired samples.
The study’s findings are promising for sustainable resource usage, reducing carbon footprint, and
reducing waste disposal volume. This research is a big step toward the Sustainable Development
Goals of the United Nations and a circular economy.

The specific surface area of II was determined by the BET method, whereas the volume and average size of the mesopores were calculated in accordance with the BJH method. The measurements of the mean size, polydispersity index and zeta potential showed colloidal instability of II. Two band gap values of 2.4 and 3.3 eV were determined using UV–Vis diffuse reflectance spectroscopy, while the measurements of photoluminescence revealed that II is active in the blue region of the visible spectrum. Testing of composite II as a pigmentary material showed that it can be used for the colouring of a ceramic glaze.

AB  - The usage possibility of 19 composites of raw refractory clays from Serbia containing approximately 53.29% of SiO2 and 26.73% of Al2O3 is presented. The sum of fluxing oxides was 57.74%, while these materials contained 32% of quartz, 29% of kaolinite and 26% of illite–mica. Dilatometry tests revealed a sudden shrinkage with the peak at approximately 1115 °C, owing to the formation of mullite. The refractoriness was in the range of 1581–1718 °C, which classifies the composites from low- to high-duty refractories. Based on correlation analysis, the refractoriness mostly depended on the content of alumina. The lightness of the fired test pieces was lower after firing when compared to the dry samples, and it decreased with the firing temperature from reddish to grayish. The study presents a novel attempt to define all the necessary properties of raw refractory clays and products fired at the 1100–1300 °C range on a laboratory level. Most of these clays can be used as natural refractory materials for ceramic and glass furnace lining. The organic matter in some of the samples influences negatively the fast-firing process.

AB  - Geopolymerization was investigated as an alternative to traditional ceramic products by developing a more sustainable approach that avoids thermal treatment. The study presents the first known alkali-activation of the raw clay and waste clay brick mixture using the solid to liquid ratios of 2.33 and 2.78. Several experimental sets were prepared to harden under varying conditions (2–4 days drying in 60 °C–70 °C and 3 h steam-curing). Non-activated and activated samples were analyzed for their physical and chemical properties after 14, 21, and 28 days. The tile-shaped specimens exhibited better initial drying behavior than the cubes and produced stronger materials with fewer cracks. Pre-curing in steam conditions induced higher flexural strength (13.7 MPa) and water absorption (13.13%) for the geopolymer tiles. The highest Si/Al molar ratio in the amorphous portion of 5.78 induced the best flexural strength. The geopolymerization process showed microstructural changes associated with the appearance of fibrous Na-zeolite nanocrystals. The degree of geopolymerization and zeolite formation was enhanced by steam-curing, but the microstructural stress and heterogeneity induced by the reactions resulted in higher water absorption. Ongoing reactions of amorphization in the bulk material and further crystallization at the surface are documented after 6 months of curing. This first detailed study reveals that the production of geopolymer ceramics from brick waste is possible, but further optimization of the activating solution and curing parameters is required.

AB  - The behavior of steel in low-cycle fatigue (LCF) is tested experimentally, in accordance with ISO 12106:2017 (E) and/or ASTM E 606-04. For this purpose, smooth specimens which are exposed to low-cycle fatigue at several levels of regulated strains and/or loads at room, elevated or reduced temperatures are used. Stress–strain response at LCF has the shape of an ideal hysteresis loop. The strain range Δε corresponds to overall loop width, while the stress range Δσ corresponds to its overall height. The paper presents a method for determining the intersection of the idealized hysteresis loop and the positive part of the strain axis in order to determine the values of elastic, Δεe/2, and plastic, Δεp/2, components of the strain amplitude to characterize the behavior of steel under low cyclic fatigue. The values of elastic and plastic components of the strain amplitude are needed to determine the characteristic curves of low-cycle fatigue, which describe the behavior of steel under the loading of low-cycle fatigue.

AB  - The most important characteristics for service safety of welded joints are those describing crack initiation and growth caused by variable loading. Crack initiation and growth caused by variable loading is the subject of numerous investigations. This paper shows the determination of parameters of the fatigue crack for constituents of welded joints produced of high strength low alloyed steel. The crack growth law of Paris establishes the relation between the applied variable load quantity or the corresponding stress intensity factor range and crack growth per cycle. Results have shown that the position of the notch and crack initiation affect the values of the stress intensity range of fatigue threshold Delta Kth and parameters in the Paris' equation.

AB  - Due to rapid development of modern highways and railroad in Serbia, the need for embankment materials has increased. Deposits of natural materials used for this purpose often contain dispersive soils. On the other hand, thermal power plants in Serbia annually generate several million tons of fly ash, which could be used to reduce the dispersion of material embedded in embankments. The paper presents the results of tests conducted for the first time in Serbia to assess the improvement in natural soil dispersivity with fly ash from a thermal power plant. The dispersivity of mixtures of fly ash and natural soil was tested according to ASTM and BS standards. To determine the optimal ash content, 10, 30 or 50% of fly ash was added to the soil samples. The results show that 30-50% of fly ash reduces the dispersivity of natural soil for one to two dispersion classes.
