Summary

This paper evaluates the high and low temperature performance of bricks made with lunar regolith simulant HUST-2 under three temperature cycling modes. It reports changes in porosity, pore size, specific heat capacity, and thermal conductivity, highlighting the impact of temperature cycling on microstructure and thermal properties. The paper discusses the evaluation of bricks made from lunar regolith simulants under thermal cycling conditions. It outlines the methodology, results, and implications for future lunar construction. The study investigates the effects of different thermal cycling modes on samples, including high-temperature, low-temperature, and combined high-low temperature cycling. The samples are labeled HUST-2-H, HUST-2-L, HUST-2-C, and HUST-2-B. The study includes analysis of mass change, density change, XRD patterns, scanning electron microscope observations, and various thermal properties such as thermal diffusion coefficient, specific heat capacity, and thermal conductivity. The results show that the samples experience changes in dimensions and properties under thermal cycling, with cracks forming during high-temperature cycling and pores remaining largely unchan
