Summary: The study evaluated the flexural performance of macro-synthetic fiber-reinforced concrete in structural deck plates, finding that the use of macro synthetic fibers can effectively enhance the flexural strength and crack load capacity of the deck plates. Additionally, a flexural strength model incorporating macro synthetic fibers showed greater accuracy compared with standard models. Further research is needed to quantitatively evaluate the impact of MFRC on the effective flexural stiffness of steel decking.

Summary: This study investigates the feasibility of reusing granite waste from natural stone processing factories in the production of foamed concrete. It is found that the foamed concrete made with granite waste exhibits similar performance to that made with fine sand, with higher compressive and flexural strength. However, it also has higher water absorption. Additionally, the use of granite waste instead of fine sand improves the life cycle assessment indicators of the specimens.

Summary: In analyzing the global waste management sector, it is evident that certain types of waste, such as rubber waste and sewage sludge, present significant challenges in terms of their management. The solidification process, by utilizing these wastes as substrates in concrete production, appears to be a potential solution. This study aimed to investigate the impact of incorporating waste materials, specifically hydrated sewage sludge and rubber granulate, into cement. The results indicated that while rubber granulate enhanced the compressive strength of the concrete, the addition of hydrated sewage sludge led to a deterioration in the mechanical properties.

Summary: The utilization of industrial waste and byproducts as alternatives to removal has become attractive due to landfill scarcity and high disposal costs. This research aims to develop systematic multiscale models to predict the compressive, tensile, and flexural strengths of concrete containing waste foundry sand (WFS) without theoretical constraints. Artificial neural networks (ANN) are found to be the most efficient model for predicting the strengths of concrete with WFS.

Summary: This study investigates the use of GFRP rebars and polypropylene fibers as sustainable materials replacements for steel rebars in high-performance concrete (HPC). By using micro silica and waste glass powder as additives, the strength of the concrete is increased. The simultaneous usage of 1.5% polypropylene fibers and GFRP rebars achieves the same flexural strength as steel rebars while reducing the weight of the concrete beam by about 4% and minimizing costs and CO2 emissions.

Summary: By incorporating aramid fiber and carbon fiber into concrete in a hybrid manner, this study aimed to enhance the static and impact mechanical properties of the material. The test results showed that the presence of a coupling agent on carbon fibers affected the mechanical strength of the reinforced concrete, with a 50-50% mix proportion of Kevlar/carbon fiber significantly improving compressive, flexural, and splitting tensile strengths. Additionally, the hybrid fiber-reinforced concrete exhibited better performance in mechanical strength and impact resistance compared to concrete with only Kevlar or carbon fibers.

Summary: This paper investigated the interfacial bond performance of macro-synthetic fiber (MSF) and evaluated its effects on the compressive and flexural performance of iron ore tailing (IOT) concrete. The results showed that the increase in IOT replacement ratio led to a deterioration in compressive strength, but the incorporation of MSF compensated for this reduction. The post-cracking performance of IOT concrete increased with the increase in fiber volume fraction, and higher fiber aspect ratios were more effective in improving post-cracking performance. New empirical equations were proposed to accurately predict the residual and equivalent flexural tensile strengths. These findings have important implications for enhancing the strength and toughness of IOT concrete.

Summary: Foam concrete is a lightweight material with excellent thermal insulation and energy absorption capacity. However, its high porosity and pore connectivity lead to low physico-mechanical and durability performance. This study used basalt fibers and calcium aluminate cement to improve the properties of foam concrete, and evaluated its mechanical performance, thermal conductivity, and durability under various conditions.

Summary: The paper presents the analysis results of regeneration possibilities for a damaged slider repaired by additive manufacturing technology. The study demonstrates the high quality of the connection zone between the original part and the regenerated zone. Hardness measurements reveal a significant increase, 35%, in the interface between the two materials when using M300 maraging steel for regeneration. Furthermore, digital image correlation technology is utilized to identify the area with the largest deformation during the tensile test, which is outside the connection zone between the two materials.

Summary: This study introduces a cement-glass composite brick (CGCB) with a printed PET-G internal scaffolding, providing an alternative to traditional masonry materials. Made from 86% waste (78% glass waste and 8% recycled PET-G), it offers a cheaper option in the construction market. Tests demonstrated improved thermal properties with the use of the internal grate, including increased thermal conductivity (5%), decreased thermal diffusivity (8%), and decreased specific heat (10%). The CGCB showed lower anisotropy in mechanical properties compared to non-scaffolded parts, indicating the positive effect of using this type of scaffolding in CGCB bricks.

Summary: This study aimed to investigate the morphology, swelling, degradation rate, and biological properties of collagen-based scaffolds modified with caffeic acid, ferulic acid, and gallic acid. The results showed that scaffolds with phenolic acid had higher swelling rate and enzymatic stability compared to pure collagen scaffolds, and exhibited radical scavenging activity in the range of 85-91%. All scaffolds were non-hemolytic and compatible with surrounding tissues. However, collagen modified with ferulic acid had potentially negative effects on hFOB cells, as evidenced by significantly increased LDH release. Nevertheless, all tested materials showed antimicrobial activity against Staphylococcus aureus and Escherichia coli.

Summary: This study investigates the mechanisms of acid corrosion on concrete tanks used on farms. Unusual test methods, such as surface morphology tests and SEM microstructural analysis, were used for preliminary detection of the problem. The experiment exposed ordinary concrete samples with different W/C ratios to 10% acetic acid for 270 days. The results show that the compressive strength of the samples stored in acetic acid decreased by 38-51% compared to the control samples, with the best results obtained for concrete samples with a W/C ratio of 0.45.

Summary: The building industry contributes greatly to climate change through the emission of large amounts of greenhouse gases. A cement composite brick with partial cement substitutes and waste material was developed through research. The physical, mechanical, and thermal properties of the fresh formula mixture and hardened concrete were tested to verify assumptions. The study investigated the role of different proportions of zeolite, metakaolinite, and micrometakaolinite, as well as recycled fibers (glass, polypropylene, and steel), in the production of cement composites. The compressive strength of the modified formula brick increased by 22% compared to the reference sample, and higher values were obtained for splitting and flexural strength. Incorporating fibers into the mixture changed the thermal properties of the concrete, and the composite matrix showed an even distribution of fibers without cracks. The new composite brick has the potential to replace traditional concrete masonry in civil engineering projects.

Summary: Foam concrete, as a typical lightweight material, has advantages such as lightweight, high fluidity, excellent thermal insulation, fire resistance, and energy absorption capacity. However, its high porosity leads to poor physico-mechanical and durability performance. This study improved foam concrete by incorporating eco-friendly fiber (basalt fibers) and aluminous cement (calcium aluminate cement) with aggregates of waste marble powder. The experimental results showed that the modified foam concrete exhibited enhanced compressive strength, low thermal conductivity, and improved resistance against magnesium sulfate and hydrochloric acid.
