Summary

The paper discusses the development and testing of an alkali-resistant fiber-reinforced concrete (ARFRC) using basalt fiber and polypropylene fiber. The study focuses on the mechanical properties of the composite material under different curing conditions and loading scenarios. The results indicate that the addition of fibers significantly improves the flexural and compressive strength of the concrete. The study also highlights the importance of fiber orientation and distribution in enhancing the overall performance of the material. The findings suggest that ARFRC can be a viable alternative for applications requiring high durability and resistance to environmental degradation. This paper investigates the influence of vacuum and high-temperature environments on the mechanical strength and microstructure evolution of alkali-activated lunar regolith simulant (AALRS). It details experimental methods, including flow tests, compressive strength tests, SEM-EDS analysis, and mercury intrusion porosimetry (MIP). The study explores the evolution of pore structure, chemical composition, and mechanical properties under simulated lunar conditions. The paper discusses the importance of in situ
