Summary: This study presents four high-workability concrete mix designs incorporating steelmaking slags with metallic and polymeric fibers. The addition of metallic fibers and ladle furnace slag (LFS) was found to reduce shrinkage and improve dimensional stability of the concrete, while the use of ground granulated blast furnace slag (GGBFS) and LFS helped to mitigate internal damage and enhance the compliance of the cementitious matrix.

Summary: This study investigated the effects of electric arc furnace ladle slag (EAFLS) on the engineering properties of cementitious mortars, specifically Ordinary Portland Cement (OPC) and alkali-activated slag (AAS) mortars. It found that EAFLS significantly reduced the compressive strength of OPC mortars and caused expansion problems after autoclaving, but had no such negative effects on AAS mortars. Furthermore, AAS mortars exhibited higher residual strength at high temperatures, thanks to the accelerated hydration process from alkali-activated technology.

Summary: This research proposes the use of industrial by-products to create bituminous mixtures which are more resistant and durable than traditional ones. By characterizing these by-products and comparing the physical and mechanical properties of the mixtures, it was found that the use of cellulose fibers can absorb a greater percentage of bitumen, while electric arc furnace slag and ladle furnace slag create mixtures with greater Marshall stability. Sustainable, durable, resistant, and high waste mixtures were developed in this investigation.

Summary: LFS, a by-product of the steel industry, is difficult to reuse due to its weak cementitious property and potential leaching of heavy metals. This study aimed to use CO2 to immobilize heavy metals in LFS and enhance its strength. Results showed that LFS had carbonation reactivity and could sequester CO2 up to 9.6% of its own mass, effectively reducing leaching of heavy metals and increasing strength.

Summary: The study investigates the carbonation technique to improve ladle furnace slag (LFS) and compares the performance and characteristics of original LFS-based geopolymer (OLFGP) and carbonated LFS-based geopolymer (CLFGP) in terms of setting time, high-temperature resistance, and chemical resistance. The results show that carbonation improves the structure of LFS and the carbonation products consist mainly of calcite. CLFGP exhibits significantly higher compressive strength, prolonged setting time, and superior chemical resistance compared to OLFGP.

Summary: This study demonstrated that ladle furnace slag (LFS) can be used as a filler to improve the compactness and maintain the compressive strength of fly ash (FA) geopolymer. The addition of LFS led to an increase in crystalline content in the FA/LFS geopolymer, which resulted in different mechanical performance compared to the pure FA geopolymer.

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.
