Summary: This paper investigates the feasibility of using recycled sand from crushed brick in self-compacting mortar. The results show that partial substitution of crushed limestone sand with recycled sand can reduce the compressive strength of the mortar, but it still falls within the European standard requirements. In addition, the incorporation of recycled sand also improves the resistance to chloride diffusion of the mortar.

Summary: Manufactured sand is an effective solution to the shortage of natural sand in the construction industry. This study investigates the influence of high fines content on the durability of high-strength manufactured sand concrete using granite and limestone manufactured sand, and analyzes the mechanism behind it through macro and micro tests. The findings indicate that the carbonation depth of manufactured sand concrete is minimized when the fines content is 10%. Additionally, a fines content of less than 15% effectively improves the chloride and sulfate impermeability of the concrete. It is observed through tests that the filling effect of fines is the primary reason for improving concrete durability, while excessive fines hinder cement hydration and adversely affect durability. Therefore, the fines content of high-strength manufactured sand concrete should be controlled within the range of 5% to 15%, with the optimal durability achieved at a fines content of 10%.

Summary: This paper examines the use of waste foundry sand (WFS) in concrete production and finds that partially replacing WFS can enhance the durability and mechanical strength of concrete, but it can also reduce the workability of fresh concrete. It is recommended to combine WFS with pozzolanic material or fiber reinforcement for future research.

Summary: This study investigates the effects of mineral additions on the physical, mechanical, and durability properties of mortars. Two local mineral additions, limestone fillers and natural dune sand, were incorporated into the mortars with different ratios. The results show that these additions have a positive effect on the compactness, mechanical resistance, and durability of the mortars, especially towards rising water table aggressiveness.

Summary: Geopolymer is an environmentally-friendly alternative to Portland Cement, which helps to reduce CO2 emissions. The use of different binders, such as bentonite and zeolite, in geopolymer manufacturing has been studied, and the substitution of river sand for metakaolin has also been investigated. The results showed that metazeolite had better performance due to its higher Si/Al ratio and more stable structure. The use of metakaolin improved the pozzolanic characteristic and enhanced the findings. Overall, the geopolymer samples showed resistance to durability effects, with the sample 50MZ50MB25MK yielding the best result.

Summary: This paper comprehensively reviews the research outcomes of the performance of concrete under various coupled aggressive actions, discusses the testing methods, interaction of two aggressive conditions, and strengthening measures, and concludes that the performance degradation under the coupled mechanical load and aggressive environments is much severer compared to the single aggressive environment. The properties of concrete are significantly affected by the severity of coupled aggressive actions, and can be improved at the early-age stage. Some enhancement methods, such as adding fly ash, silica fume, slag, fibers or air-entraining agents, are effective in improving the durability of concrete under coupled aggressive environments.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

Summary: Tailings dam break and leakage accidents pose a threat to the safety of people in mining areas and cause severe environmental pollution. This study focuses on solidifying tailing sand using microbial induced calcite precipitation (MICP) to improve strength and fix heavy metals. The curing time of MICP bio-cemented tailings is found to significantly impact the strength of tailings, while its effect on heavy metal fixation is minimal. The optimized MICP curing time is 10 days, resulting in improved strength and cementation of tailings particles.

Summary: Incorporation techniques of phase change materials in cementitious composites have a significant influence on thermal properties. This study investigated the thermal behavior of low-temperature PCM when subjected to varying temperature change rates and pore confinement inside the porous network of lightweight aggregates. The results showed that ramp rates affect the nucleation and crystallization growth process during the phase transition, and the pore structure of the aggregates affects the supercooling phenomenon and confinement pressure of the PCM.

Summary: This study investigates the fatigue behavior of concrete under different stress reversal conditions. The results indicate that stress reversal generally causes more severe damage and reduces the cycles to failure compared to tensile fatigue. Additionally, adding some level of compression contributes to the energy required for failure under stress reversal fatigue. Specimens with higher concentration of fractured aggregates achieve longer fatigue lives.

Summary: The susceptibility of building stones to fire and high temperature was investigated in this study by examining their physical and mechanical properties. The results show that both compressive and tensile properties of stones are affected by temperature changes. The tensile strength is particularly sensitive to temperature changes, requiring special attention to the components subjected to tensile stress in stone buildings. Principal component analysis was used to predict the mechanical properties of stones, providing a new method for calculating the residual mechanical properties after high temperature or fire.

Summary: This paper investigates the correlation between the friction coefficient and the surface roughness of concrete-to-concrete interfaces. Experimental tests were performed on specimens with different surface treatments, and the surface roughness parameters were analyzed and correlated with the shear strength and friction coefficient. The results showed that certain roughness parameters had a strong positive correlation with the friction coefficient, while others had little or no correlation. A novel combined roughness parameter with optimized correlation was proposed.
