AB  - This study compared the performance of self-compacting concrete (SCC) based on fly ash addition and limestone filler. A SCC prepared with Portland cement, river sand, and limestone filler was used as a reference sample. Additional experimental self-compacting concretes with different types of fine aggregates, fillers, and special additives for increasing freeze-thaw resistance were prepared and optimized. The correlation between mix design, i.e., percentage of barite sand and additives, and properties of fresh SCC (slump-flow test, V-funnel test, and L-box test), as well as properties of hardened SCC (compressive strengths), were investigated and discussed.

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.

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.

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.

AB  - Self-compacting concrete (SCC) exhibits increased flowability in comparison with the conventional vibrated concrete. This is most often achieved through the incorporation of high amounts of extra-fine particles (i.e. mineral fillers) in the composition of self-compacting concrete. The purpose is to limit the share of cement while reaching the required large paste content. The components and their proportions, as well as type and particle size of filler, casting, manufacturing and curing conditions of SCC, significantly influence the concrete’s fresh and hardened properties. Among fillers employed in SCC, fly ash is one of the most frequent due to its availability and the low cost. Fly as is an industrial by-product and a highly efficient mineral additive whose role is reflected in improvements of microstructure packing, strength and durability of non-shaped composite building materials such as self-compacting concrete. A comparative study of performances of SCC with different quantities of fly ash and standard SCC with limestone filler was conducted in this study. The experimental program included the production of reference self-compacting concrete based on Portland cement and limestone filler (P1) and additional three experimental self-compacting concrete mixtures (P2, P3, P4) with different quantities of fly ash addition. Behaviour of self-compacting concrete in the fresh state is primarily influenced by type of mineral additive used. The effect that fly ash addition has on the physical behaviour and mechanical properties of fresh experimental SCC concrete samples was discussed. The properties and technology of self-compacting concretes in their fresh state in regard to the alternations in water/cement (w/c) ratios are monitored and explained in this paper. Concrete mixtures with fly ash had lower density in comparisons with the referent concrete. For the same class of consistency, higher amount of water was needed for preparation of SCC mixture with fly ash. Increasing w/c ratio induced more favourable properties of self-compacting concrete in its fresh state.

AB  - Phyllosilicate mineral pyrophyllite possesses talc’s characteristic softness and crystalline structure, but it also exhibits high refractoriness. Pyrophyllite is predominantly being used in the ceramic materials (tiles, porcelain) as a replacement of quartz, clay or feldspar. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures. Its ion-exchanging properties are crucial for stabilization of the toxic elements in building materials. In this study pyrophyllite is used as a mineral additive for two types of construction products: traditional ceramic materials and refractory mortars. The experimental samples were prepared using 50 % of pyrophyllite and 50 % of refractory clay, ceramic clay, and carbonate brick clay, respectively. The samples were formed into discs or tiles using the compression method. The following characteristics have been investigated: resistance to firing (900 – 1300°C), carbonate content, plasticity coefficient, dimensional changes after drying at 105°C and upon firing, water absorption, and mechanical strength. Refractory samples were prepared using andalusite as aggregate, ordinary Portland cement and/or high aluminate cement as binder, and pyrophyllite as an additive (10 %, 20 %, and 30 %). Compressive and flexural strength both at normal and at elevated temperature were tested on the samples, along with the refractoriness. The changes that pyrophyllite addition brings to the material’s mineral composition, microstructure, as well as to bonding/sintering mechanisms were monitored using instrumental techniques (DTA, TGA, XRD). The aim of the investigation was to prove potential suitability of pyrophyllite as efficient and sustainable resource for the production of ceramic and refractory materials.

abstract = "Phyllosilicate mineral pyrophyllite possesses talc’s characteristic softness and crystalline structure, but it also exhibits high refractoriness. Pyrophyllite is predominantly being used in the ceramic materials (tiles, porcelain) as a replacement of quartz, clay or feldspar. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures. Its ion-exchanging properties are crucial for stabilization of the toxic elements in building materials. In this study pyrophyllite is used as a mineral additive for two types of construction products: traditional ceramic materials and refractory mortars. The experimental samples were prepared using 50 % of pyrophyllite and 50 % of refractory clay, ceramic clay, and carbonate brick clay, respectively. The samples were formed into discs or tiles using the compression method. The following characteristics have been investigated: resistance to firing (900 – 1300°C), carbonate content, plasticity coefficient, dimensional changes after drying at 105°C and upon firing, water absorption, and mechanical strength. Refractory samples were prepared using andalusite as aggregate, ordinary Portland cement and/or high aluminate cement as binder, and pyrophyllite as an additive (10 %, 20 %, and 30 %).

AB  - A comparative study of performances of self compacting concrete (SCC) with fly ash and limestone filler was conducted. The experimental program included the production of reference SCC designed with Portland cement, river sand and limestone filler and four experimental self compacting concretes with different types of fine aggregates, fillers and special additive to increase freeze-thaw resistance. The effects that different sand and additions have on the properties of fresh SCC (slump-flow test, V-funnel test, and L-box test) and compressive strengths in early ages (3 and 7 days) were investigated and discussed.

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  - Micro-silica is a highly efficient mineral additive whose role is reflected in improvements of microstructure packing, strength and durability of non-shaped composite building materials such as concrete and mortar. A comparative study of performances of rendering mortars with different quantities of micro silica was conducted. The experimental program included production of reference mortar based on Portland cement and quartz sand (CM) and three mortars with 5, 10, and 15 % addition of micro silica (SCM-5, SCM-10, and SCM-15). The effect that micro silica addition has on the thermal behavior and mechanical properties of mortars was discussed. Hydration mechanisms and thermally induced reactions were studied at temperatures ranging from ambient to 1100 degrees C by differential thermal analysis. The results were supported by X-ray diffraction analysis. The cementing efficiency of micro silica was assessed by cavitation erosion test. The changes in the morphology of mortar samples prior and upon cavitation testing were monitored by means of the scanning electron microscope imagining. It was found that 5 % of superfine micro silica (SCM-5 mortar) has positive effects on mechanical strengths (15 % increase in compressive strength) due to microstructure densification arising from the successive filling of voids by the micro silica. Addition of micro silica also improved the cavitation erosion resistance in comparison with reference cement mortar (SCM-5 showed cavitation velocity as low as 0.09 mg/min). This qualifies mortars with micro silica addition as building materials which can be safely employed in potential hydro-demolition environment.

AB  - Rare earth elements (REE) are frequently referred to as ingredients for enhancements in modem industry, as they are extensively applied in many industrial branches due to their accented electro-magnetic and optical properties. REE have end-utilizations as catalysts, magnets, and as dopants for ceramic materials. Rare earth minerals are scarce therefore the unconventional REE-containing resources such as waste materials and industrial byproducts are continuously being investigated. Coal combustion products comprise REE concentrations varying between 200 ppm and 1500 ppm. This quantity can be isolated though the extraction procedure. In this study, the five stages extraction was conducted on the coal combustion ash from the selected landfill site. The extractions of 32 elements (As, Ga, Ce, Be, Ge, Nd, Cr, Zr, Eu, Cu, Nb, Gd, Co, Mo, Dy, Li, Ag, W, Mn, Cd, Au, Ni, In, Hg, Pb, Sn, Ti, V, Sb, Th, Zn, and La) were conveyed. Chemical analyses were conducted via XRF, ICP-OES, ICP-MS, and MS techniques. The complexity of the obtained data was examined by Principal component analysis and Cluster analysis in order to derive interconnections between quantity of elements and landfill characteristics, as well as mutual relationships among the elements of interest, and to assess the accomplishment of REE recovery from the coal ash.

AB  - The numerical model of the granular flow within an aggregate mixture, conducted in the vertical static and/or the conveyor blender, was explored using the discrete element method (DEM) approach. The blending quality of limestone fine aggregate fractions binary mixture for application in self-compacting concrete was studied. The potential of augmenting the conveyor mixer working efficiency by joining its operation to a Komax-type vertical static mixer, to increase the blending conduct was investigated. In addition the impact of the feed height on the flow field in the cone-shaped conveyor mixer was examined using the DEM simulation. Applying the numerical approach enabled a deeper insight into the quality of blending actions, while the relative standard deviation criteria ranked the uniformity of the mixture. The primary objective of this investigation was to examine the behavior of mixture for two types of blenders and to estimate the combined blending action of these two mixers, to explore the potential to augment the homogeneity of the aggregate fractions binary mixture, i.e., mixing quality, reduce the blending time and to abbreviate the energy-consuming.
