The glass fiber reinforced cement GRC has several advantages such as good tensile strength, good bending strength, good shock strength and light weight. Its usable range is restricted by reducing performance for a long time. There are many theories for that mechanism in China and abroad. Several measures for improving its durability are put forward such as changing the chemical composition of glass fibers, changing performance of its matrix, treating the surface coating of glass fibers, improving the interface, etc. At present, the study of its durability is facing how to determine the testing method and standard of accelerated ageing, to understand the mechanism of reducing GRC performance under wet envornment for a long time, to reduce the high cost of low alkalinity cement, and to further improve the earlier stage strength reduction of the common silicate cement with admixtures after changing performance, and the galss fiber performance.
