Summary: The study investigates the sulfate and chloride resistance of cement composites manufactured using electrolyzed water, showing that the electrolyzed water-based specimens exhibit enhanced durability performance with reduced compressive strength losses and corrosion potential compared to control specimens. This improvement is attributed to the less porous and compact microstructure of the hardened composites, leading to lower ingress of deleterious agents.

Summary: The influences of Ca2+ on the early degradation process and mechanism of cast-in-situ structures subjected to sulfate, chloride and combined attack were investigated. Mortar specimens were prepared, immersed in different solutions for 28 days, and subjected to various tests. It was found that internal aggressive corrosion sources negatively affect the strength development of cement mortar, while premixed chlorides accelerate the degradation process. On the other hand, cement mortar with premixed Ca2+ shows better strength development and durability against corrosive conditions, suggesting a potential way to improve the durability performance of cast-in-situ concrete in sulfate-rich environments.

Summary: This paper explores the use of organic light-emitting diode glass (OLED) display waste as a partial replacement of cement binder in concrete. The study developed concrete materials with 10%, 20%, and 30% substitution of ordinary Portland cement (OPC) by OLED powder, and evaluated their mechanical properties and durability characteristics. The results showed that incorporating OLED powder led to an 8% increase in strength after 28 days, as well as improved resistance to chloride-ion penetration and sulfate attack. The addition of OLED waste in concrete also enhanced corrosion resistance and reduced environmental burden and concrete cost.

Summary: The study investigates the impact of sulfate environment on the mechanical properties of pretreated RCA concrete using a PVA agent. The use of 32% RCA in the concrete mix exhibited the best durability, while higher strength was observed in mixes with RCA pre-soaked in PVA. Increasing the amount of RCA pre-soaked in PVA led to increased hydration and decreased internal voids, impacting the absorption rates under different curing conditions.

Summary: In general, fly ash, slag, silica fume, and metakaolin can effectively mitigate sulfate attack, but the performance depends on replacement rate, sulfate cation exposure, and their chemical and physical properties. Performance was found to be improved with increased dosage rates for all SCMs except silica fume and Class C fly ash, and mixed for metakaolin and silica fume in magnesium sulfate at higher replacement rates.

Summary: This study proposed a nondestructive method using ultrasonic shear waves to detect steel-concrete interface debonding caused by the top-bar effect. Experiments were conducted by casting horizontal reinforcements at different heights in a concrete wall to create interfacial defects underneath the top bars, and the results showed that the signal amplitude increased with the height of the bars. Utilizing the increasing difference between the high-frequency component and the excitation frequency of the signal could be a way to monitor the top-bar effect nondestructively.

Summary: The use of bacterial cement and conventional cement slurry coating treatment on recycled coarse aggregates helps overcome shortcomings such as excessive water absorption, weak interfacial transition zone, and high porosity. Concrete with microbial carbonate precipitation (MCP) treated aggregate performs better than untreated recycled aggregate based concrete mixes, but marginally higher environmental impacts were observed due to additional emissions associated with the biocement treatment of RCA. Further environmental mitigation strategies are being considered to improve the environmental performance of concrete with MCP treated aggregates.

Summary: Biomediated soil improvement has emerged as a promising solution for enhancing soil engineering properties in the past decade. The efficacy of biocementation depends largely on the material properties of the precipitated crystals, which are influenced by the concentration of cementation reagents. In this study, specific microbes were investigated for their biocementation potential at different concentrations of cementation media (CM). The soil strength improvement was evaluated through a needle penetration test, and the biochemical properties of the microbes were analyzed to understand the reasons behind the variation in penetration resistance. The findings suggest that the concentration of CM plays a significant role in the response of microbes, and the morphology, texture, and quantity of precipitated CaCO3 crystals are important factors influencing the strength of the biocemented soil.

Summary: Bacterial biocementation has the ability to heal cracks in concrete, but there is a concern about the potential corrosion caused by the materials used. This paper examines the performance of bacterially healed reinforced concrete when exposed to chloride-induced corrosion. Different calcium sources were used for the healing process, and electrochemical techniques and ultrasonic-guided waves were used to assess the state of corrosion. The study found that the presence of electrolytes in the healing fluid affected the electrochemical measurements and gave misleading results, but the ultrasonic-guided waves method provided an accurate assessment of corrosion.

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.
