Summary: This study investigates the flame retardancy of flax fiber reinforced phenolic composites (FFRPCs) by applying a phosphorus-containing flame retardant (FR) DMMP and modifying the phenolic resin with nano-sized MMTs. The water absorption performance, flammability, and interlaminar properties of the composites were evaluated. The results show that using DMMP to pretreat flax fiber and adding MMTs to the phenolic resin can significantly improve the flame retardancy of FFRPCs.

Summary: An effective approach to achieve sustainable development and environmental protection is to use shale ceramsite (SC) to produce high-strength lightweight concrete (HSLWC). This study investigated the effect of graphene oxide (GO) on the mechanical properties and durability of HSLWC manufactured from SC. The experimental results showed that the optimal addition level of 0.05% GO enhanced the compressive strength, flexural strength, splitting tensile strength, chloride penetration resistance, freezing-thawing resistance, and sulfate attack resistance of HSLWC.

Summary: Wool derived keratin is a potential biopolymer that can serve as a cheap, sustainable, renewable material source for specialized biomedicine products. Utilizing eco-friendly, recyclable ionic liquids as solvents opens up new possibilities for processing natural materials from livestock industries. This study developed a technique for rapidly dissolving keratin in ionic liquid using probe sonication without external heating. The optimized extraction process included considerations such as the type of ionic liquid, sonication time, sample loading, and acoustic power. The properties of the regenerated keratin were analyzed using various techniques, showing improved thermal properties and specific protein structures. Further efforts are needed to implement this economical, quick, and environmentally friendly technique at a larger industrial scale.

Summary: Basalt fiber-reinforced concrete (BFRC) has excellent mechanical properties and durability. The addition of basalt fiber with specific dimensions can effectively improve the mechanical properties of concrete and enhance its resistance to chloride erosion and sulfate attack, while also increasing impermeability. Future research should focus on the mechanical properties and durability of BFRC under high temperatures and after damage, as well as the toughening mechanism of basalt fiber in hydraulic concrete.

Summary: After 15 years of exploitation, numerous instances of damage were observed on the concrete pavement motorway located in northern Germany. Detailed analysis on collected cores revealed that the cracks in the aggregate were a result of advanced alkali-silica reaction. The study also found no impact from de-icing agents on the destruction of the concrete pavement. These findings offer a valuable supplement to German research in the previously unanalyzed region of Rostock.

Summary: The durability of concrete pavements in wet-freeze climate is affected by deicing salts and the development of alkali-silica reaction (ASR). The performance of different aggregate mixtures in concrete was studied using RILEM test procedure. Air-entrained concrete exposed to temperature changes, wetting-drying, and NaCl solution immersion showed expansion and changes in elastic modulus. Micro- and cryptocrystalline silica in aggregates greatly influenced the expansive behavior, and the replacement of nonreactive limestone sand with moderately reactive quartz sand enhanced concrete expansion.

Summary: Diagnostic tests were conducted on a section of jointed, unreinforced highway pavement that had been in service for 15 years. The tests revealed that premature pavement damage, mainly in the form of visible cracking, was caused by the presence of reactive quartz in the quartzite aggregate. Other factors such as heavy vehicle traffic and freeze-thaw aggression also played a role in the damage. The findings highlight the importance of understanding and managing the detrimental effects of reactive quartz and external factors on highway pavement performance.

Summary: This study presents the experimental results of using low-grade calcined clay to mitigate alkali-silica reaction (ASR). Domestic clay with certain compositions was calcined at different temperatures. The pozzolanity of the clay was determined, and the performance of calcined clay in mitigating ASR was evaluated using reactive aggregates. The results showed that replacing cement with calcined clay reduced the expansion of mortar bars, and a higher replacement percentage resulted in better ASR mitigation. The influence of calcination temperature was less clear, with opposite trends observed when using 10% or 20% calcined clay.
