Summary: This study investigates the impact of concrete pavement surface characteristics on ice-pavement adhesion. The results indicate that improving hydrophobicity and raising the freezing temperature were effective approaches for reducing ice-concrete adhesion. Different texture parameters had different effects on the adhesion of hydrophilic and hydrophobic concrete. The order of influence on ice-concrete adhesion was identified as surface area, water contact angle, mean texture depth, freezing temperature, and skewness.

Summary: This study investigates the activation effect of Na2SO4, Na2CO3, and Na2SiO3 on the GBFS-SS composite pavement concrete. The results show that Na2SO4 and Na2SiO3 can promote the strength development of the GBFS-SS composite cementitious system, while Na2CO3 has limited improvement. The combined activation of Na2SiO3 and Na2SO4 is more effective in improving the performance of pavement concrete.

Summary: This study compares the abrasion characteristics of concrete pavements with exposed aggregates and transverse tining textures. Dressing wheel abrasion tests show that the abrasion depths in concrete with exposed aggregate textures are significantly lower than those with transverse tining surfaces. The long-term durability of the exposed aggregate texture can ensure resistance against abrasion and surface deterioration during the pavement service life.

Summary: Compared to OPC, CSA displays very early-age strength and faster heat-releasing rate during hydration, with three exothermic peaks identified during the process. The addition of SF affects the timing of reaction peaks, while decreasing w/c significantly reduces heat release peaks. An optimal use of SCMs in CSA pastes under different w/c can greatly decrease heat releasing while maintaining the required strength.

Summary: Due to its low carbon footprint, calcium sulfoaluminate (CSA) cement has gained attention from cement chemists. Relevant studies have explored the use of supplementary cementitious materials (SCMs) to improve CSA cement properties. However, the low alkalinity of SCMs limits their full exploitation in CSA cement. This study investigates the impact of different alkalis on the hydration of CSA-fly ash (CSA-FA), finding that calcium hydroxide (Ca(OH)2) promotes hydration and sodium hydroxide (NaOH) inhibits hydration of CSA.

Summary: The influence of industrial-grade heavy calcium carbonate powder (IHCP) on the performance of white high-strength concrete (WHSC) was systematically studied. IHCP was found to improve the workability, whiteness, and mechanical properties of WHSC. However, it reduced the impermeability and carbonation resistance, and increased the drying shrinkage. Increasing the fineness of IHCP had limited effect on WHSC performance but increased the grinding and raw material costs. WHSC with 15% of 850 m2/kg IHCP had the best cost performance.

Summary: This study investigated the effect of internal curing on shrinkage of calcium sulfoaluminate cement (CSA) concrete under sealed condition and dry/wet cycles. The results showed that higher autogenous shrinkage and total shrinkage occurred in CSA100 with lower water-to-binder ratio (w/b) compared to CSA30. Internal curing effectively reduced both autogenous shrinkage and deformation amplitude during dry/wet cycles, especially for concrete with lower w/b. The internally cured CSA100 exhibited reduced total shrinkage and deformation amplitude compared to its normally cured counterpart. Moreover, the shrinkage stress of the internally cured CSA100 was significantly lower than that of the normally cured CSA100.

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: 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.
