AB  - Waste tires have long been a challenge for waste disposal. In an effort to mitigate the impact of solid waste on the environment and recycle it as much as possible, research has been conducted into the possibility of using this waste in concrete mixes. However, the use of these waste materials in concrete is still not popular due to the lack of knowledge of the properties that can be obtained with this material. Hence, the aim is to use waste material in the production of concrete, and that concrete mixes with this material have satisfactory performance. The paper presents the results of research on concrete in which volume replacement of fine aggregate with crumb rubber was performed in the amount of 5%, and this concrete was compared with the control concrete mix and aerated concrete. All concrete are made with a water-cement factor of 0.45. The performance of fresh concrete was monitored for 10, 30 and 60 min. In the case of concrete with the addition of crumb rubber, after 60 min, higher values of air content were obtained, and lower values of volume mass of fresh concrete compared to the initial measurements. The obtained test results of hardened concrete indicate that concrete with crumb rubber has a lower compressive strength compared to the control concrete mix, while compared to aerated concrete, they obtain approximate compressive strength values.

AB  - Following the emergence and establishment of performance-based design as a widely recognized
and applied practice, numerous significant advances in computational techniques have been
made. Arguably, nonlinear methods of analysis – static or dynamic – provide the most detailed
and accurate insight into behavior of the structure which is designed or assessed. While the
current codes of practice permit their use, provisions are vague in some aspects, leaving many
decisions and assumptions up to the engineer. This paper aims to expand the relatively limited
experience with implementation of different distributed plasticity modeling approaches through
a case study based on experimental data. Some particulars of the behavior of structural elements
made of strain-softening materials, and of their corresponding numerical models, are briefly
introduced. Case study is conducted to provide an overview on the procedures for inelastic
analysis of reinforced concrete frames through a side-by-side comparison of four alternative
approaches for modeling of RC beams and columns with one-dimensional distributed plasticity
finite elements with fiber-discretized cross sections. The analyzed structure consists of a
reinforced concrete column with a fixed base, which is, under varying axial loads, subjected to
monotonic and cyclic lateral displacements applied at its top. Models comprised of force-based
elements with different arrangements of integration points, as well as of displacement-based
elements, are compared. Advantages, limitations and special considerations which need to be
taken into account for each of the approaches are demonstrated through the example. Influence
of concrete confinement is studied by analyzing another column with a different arrangement of
transverse reinforcement. Global structural response is evaluated by comparison of pushover and
cyclic curves for different models. Influence of modeling approach on objectivity of the local
response and the corrections which need to be made for certain approaches are showcased by
moment-rotation curves of the yielded section at the column base. Considerations and findings
presented in the paper, along with other published case studies, can be used for reference when
preparing a computational model for inelastic analysis of a reinforced concrete structure.

AB  - The performance of thermo-insulation rendering mortars with alternations in ratios of powdered cordierite and talc was examined. The goal was to confirm that recycled kilnware cordierite can be reapplied in the mortar design without significant deterioration in performance in comparison with OPC mortar. Differential thermal analysis was employed for examining thermally induced reactions. The cavitation erosion, in testing sequences ranging from 30 to 120 minutes, was used to assess the compactness of the mortar structure. The physico-mechanical properties of experimental mortars were investigated. The morphologies of the mortar tablets upon cavitation were studied using a scanning electron microscope. It was established that cordierite and talc filler in amounts up to 20% enhance microstructural packing and mechanical strengths due to improved cementation and therefore contribute to cavitation erosion resistance. Higher amounts of talc cause structural degradation and mass loss during cavitation tests. Reducing manufacturing costs, energy consumption, and greenhouse gas emissions are the main objectives of the production of this waste-based construction composite, as the reuse of waste materials can help achieve a number of Sustainable Development Goals.

AB  - Smelting used to be less efficient; therefore, wastes obtained from historical processing at smelter plants usually contain certain quantities of valuable metals. Upon the extraction of useful metal elements, metallurgical slag can be repurposed as an alternative mineral raw material in the building sector. A case study was conducted, which included an investigation of the physico-chemical, mineralogical, and microstructural properties of Pb–Zn slag found at the historic landfill near the Topilnica Veles smelter in North Macedonia. The slag was sampled using drill holes. The mineralogical and microstructural analysis revealed that Pb–Zn slag is a very complex and inhomogeneous alternative raw material with utilizable levels of metals, specifically Pb (2.3 wt.%), Zn (7.1 wt.%), and Ag (27.5 ppm). Crystalline mineral phases of wurtzite, sphalerite, galena, cerussite, akermanite, wüstite, monticellite, franklinite, and zincite were identified in the analyzed samples. The slag’s matrix consisted of alumino-silicates, amorphous silicates, and mixtures of spinel and silicates. Due to the economic potential of Pb, Zn, and Ag extraction, the first stage of reutilization will be to transform metal concentrates into their collective concentrate, from which the maximum amount of these crucial components can be extracted. This procedure will include combination of gravity concentration and separation techniques. The next step is to assess the Pb–Zn slag’s potential applications in civil engineering, based on its mineralogical and physico-mechanical properties. Alumino-silicates present in Pb–Zn slag, which contain high concentrations of SiO2, Al2O3, CaO, and Fe2O3, are suitable for use in cementitious building composites. The goal of this research is to suggest a solution by which to close the circle of slag’s reutilization in terms of zero waste principles. It is therefore critical to thoroughly investigate the material, the established methods and preparation processes, and the ways of concentrating useful components into commercial products.

AB  - The primary objective of this study was to look into the role of titanium dioxide in the production of corundum-based mortars, with a focus on finding the optimal mortar composition for achieving improved mechanical and dielectric performances. Changes in the mix design (different binders, different additive dosages), as well as their effects on the hydration pathway, chemical bonds, phase modifications, and microstructure, were examined. These findings were then correlated to the designed mortars' mechanical strengths and dielectric properties. Experimental mortars were produced with binders made from ordinary Portland cement, high alumina cement, and their mixtures, and corundum as aggregate. Titanium dioxide was employed as an additive (3 and 5 wt%). Nine different mortars were submitted for comprehensive mineralogical and microstructural characterization upon curing and solidification. The compressive and flexural strengths were monitored throughout the 28-day period. The dielectric constant (εr), dielectric loss tangent (tan δ), and electrical resistivity (ρ) were measured over a frequency range of 100 Hz to 1 MHz. XRD analysis highlighted the appearance of mayenite as a dielectric-prone phase in the samples doped with titanium dioxide. Differential thermal analysis and FTIR spectroscopy identified a higher amount of extra-low crystalline phase in OPC and HAC mortars with TiO2 addition, which accelerated hydration mechanisms, created a surplus of hydration products and made a more compact cement matrix. TiO2 added in 3 wt% amount led to higher mechanical strengths in OPC-based mortars, while it improved the dielectric properties of HAC mortars.

AB  - Self-compacting concrete (SCC), a non-shaped composite building material, has
improved microstructure packing, strength, and durability thanks to the use of fly ash, a
highly effective mineral additive. Performances of SCC with fly ash and conventional
SCC with limestone filler were compared. Additional experimental self-compacting
concretes were made and adjusted with various types of fine aggregates, fillers, and
unique additives to increase freeze-thaw resistance. The relationship between the
proportion of barite sand and additives and the properties of SCC was investigated and
discussed. Tests of freeze-thaw resistance with and without de-icing salts are the main
focus of these articles.

AB  - Global warming and the emission of CO2 into the atmosphere is becoming a bigger
problem in the world every year. The desire for a global increase in production and the
ever-increasing development of industry are the cause of the increased amount of waste
in landfills and environmental pollution. Concrete is the most used construction material
in the world, and the production of its main ingredient, cement, is responsible for about
7% of CO2 emissions in the world. Application of waste materials and by-products that
end up as waste during some industrial process in production can find further
application in concrete. Such materials can be used as mineral additives or as aggregate
fillers, for partial or complete replacement of natural stone aggregate and/or cement. In
this work, volume replacement of the fine fraction with 2.5 and 7.5 % crushed rubber
was performed. Based on the test results of fresh concrete, in concrete with rubber
addition, the slump consistency and bulk density decrease, and the air content
increases. A drop in compressive strength of concrete was observed with an increase in
the rubber content of 7.5%.

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 phyllosilicate mineral pyrophyllite can be utilized in cementitious composites design to replace quartz powder and boost workability, early strengths, and refractoriness. Employed as a mineral additive or microfiller, pyrophyllite is stable at high temperatures owing to its thermal conversion into mullite.
In this study, mortar samples were prepared using andalusite as aggregate, high-alumina cement as a binder, and pyrophyllite as an additive (15%, 25%, and 35%). Compressive and flexural strengths, both at normal and elevated temperatures (samples were thermally treated at 1000°C) were tested on the samples, along with the refractoriness. The effects of pyrophyllite addition on the mineral composition, microstructure, and bonding and sintering mechanisms were studied using instrumental analytical techniques. Pyrophyllite acted as additional pozzolana during cement hydration as it formed microreinforcement
in the shape of crystalline folia within the microstructure, which improved the
compressive strengths of mortars. The differential thermal analysis highlighted that pyrophyllite did not negatively interfere with the cement hydration route; moreover, this mineral additive behaved as pozzolana. The investigation demonstrated that pyrophyllite additions of up to 25% can be used in cementitious composites without affecting their performance.

AB  - Many studies on techniques for diminishing the environmental impact, reducing greenhouse gas emissions, and decreasing industrial and biowaste have been conducted with the mutual goal of achieving sustainable development. The use of industrial byproducts as raw materials for cement clinker production is becoming more common in the Portland cement industry. Eggshell is a biowaste produced in huge quantities by households and the food industry. Eggshell powder has a trigonal-calcite structure and properties similar to limestone; therefore, it can substitute limestone in the cement clinker mix design. In this work, bio-waste cement was produced at temperatures below the standard 1470°C utilizing mechanically activated eggshell powder. Under the same conditions as bio-waste cement, limestone cement clinker was also synthesized. Instrumental tests (X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, and thermogravimetry analysis) were employed to analyze the mineral phases in the produced cements. The results showed that eggshell-cement had four major cement clinker phases (C3S, C2S, C3A, and C4AF) that were identical to those in ordinary commercial Portland cement. As a result, this study demonstrated that it is possible to recycle eggshell waste to partially substitute limestone as a raw material for cement clinker manufacturing.

AB  - According to earlier physical-chemical and mineralogical analysis, slag from "Topionica"- Veles (Northern Macedonia) represents a potentially important raw resource. It is an inhomogeneous raw material with considerable nonferrous metal content, particularly Pb, Zn, Cu, and Ag (considered as a precious metal). This technogenic resource's mineralogical analysis revealed a very complex composition: amorphous phase, lead alloys, zinc alloys, wüstite (FeO), sphalerite, galena, cerussite, elemental silver, elemental copper, elemental iron, magnetite, spinel, rutile, hematite, troilite (FeS). The most abundant phase is an amorphous phase (glassy matrix) composed of spinel, silicate, and mixed (spinel-silicate). The sample has substantially less wüstite, that appears as skeletal inclusions in the glassy matrix. SEM investigation revealed the presence of Fe-Mn-Zn spinels in the Pb-Zn slag, as well as Pb and Zn alloys. These alloys are primarily composed of Cu. The grains of these phases are up to 100μm appearing as inclusions (usually as complex inclusions with a glassy matrix of elemental iron and wüstite). Grains bigger than 100μm in length are typically free or have simple inclusions. The biggest grains in the aforementioned stages have diameters of up to 300μm. The mineralogical study revealed that the Pb-Zn slag is a very complex raw material. It is required to investigate it in detail and establish the methods in which it can be done in order to value it and eventually apply it. Every stage of the preparation process has to be accompanied by numerous analyzes that will indicate the relevance of the preparation process and ways of concentrating useful components into commercial products.

It is an inhomogeneous raw material with considerable nonferrous metal content, particularly Pb, Zn, Cu, and Ag (considered as a precious metal). This technogenic resource's mineralogical analysis revealed a very complex composition: amorphous phase, lead alloys, zinc alloys, wüstite (FeO), sphalerite, galena, cerussite, elemental silver, elemental copper, elemental iron, magnetite, spinel, rutile, hematite, troilite (FeS). The most abundant phase is an amorphous phase (glassy matrix) composed of spinel, silicate, and mixed (spinel-silicate). The sample has substantially less wüstite, that appears as skeletal inclusions in the glassy matrix. SEM investigation revealed the presence of Fe-Mn-Zn spinels in the Pb-Zn slag, as well as Pb and Zn alloys. These alloys are primarily composed of Cu. The grains of these phases are up to 100μm appearing as inclusions (usually as complex inclusions with a glassy matrix of elemental iron and wüstite). Grains bigger than 100μm in length are typically free or have simple inclusions. The biggest grains in the aforementioned stages have diameters of up to 300μm. The mineralogical study revealed that the Pb-Zn slag is a very complex raw material. It is required to investigate it in detail and establish the methods in which it can be done in order to value it and eventually apply it. Every stage of the preparation process has to be accompanied by numerous analyzes that will indicate the relevance of the preparation process and ways of concentrating useful components into commercial products.",

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  - 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 implementation of procedures for designing building barriers for protection against gamma and X radiation, the unavoidable question of choosing construction materials with appropriate mechanical and radiation characteristics for protective barriers arises. Based on engineering practice, it is necessary to compare different types of concrete used for the construction of facilities where there are sources of gamma and X radiation, such as in cases where radiation sources appear in medical facilities with linear accelerators, cyclotron installations for accelerating nuclear particles, in the environment of nuclear reactors, in radioactive waste storages, or in radiation sterilization unit s. In the cost-benefit analysis, several criteria are used to evaluate the characteristics of the concrete, so that in addition to the mechanical characteristics, the radiation characteristics of the construction material are also considered. One of the most important characteristics of concrete for radiation protection is its total mass attenuation coefficient. In this paper, computer code XCOM was used for the calculation of the total mass attenuation coefficients in energy range from 0.01MeV to 100 MeV for three types of concrete: ordinary concrete, concrete with barite and concrete with limonite and steel. Based on the comparison of calculation results, it was concluded that concrete with limonite and steel has greater protective power than other two concrete types for the gamma and X radiation energy less than 30 keV. The second important conclusion is that the concrete with barite has greater protective power than other two concrete types in the range of photon energy from 30 keV to 300 keV, and for photon energy greater than 6 MeV. A detailed analysis of the calculation results found that in the energy range of 400 keV to 6 MeV values for the total mass attenuation coefficients are approximately the same for three different types of concrete.

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.

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  - 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 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.
