However, their tensile strength is quite low, usually only 10−15% of their compressive strength, which leads to the fact that cement-based materials need to work in conjunction with steel bars with excellent tensile properties when they are utilized in the engineering construction. In terms of mechanical properties, the compressive strength of cement-based materials is quite high. Mechanical properties affect the safety of building structures, and durability is associated with the service life of buildings. The mechanical properties and durability of cement-based materials are of great significance. Finally, there is a discussion of the durability of C-S-H, with special reference to the carbonization and chloride/sulfate attacks. An evaluation of the mechanical properties of C-S-H has also been included in this review. The progress related to C-S-H microstructure is explored from the theoretical and computational point of view. The preparation method of C-S-H gels has been well documented, but the quality of the prepared C-S-H affects experimental results therefore, this review studies the preparation method of C-S-H under different conditions and materials. C-S-H gels in Portland cement paste account for 60–70% of hydrated products by volume, which has profound influence on the mechanical properties and durability of cement-based materials. The main product of hydrated products of cement-based materials is calcium silicate hydrate (C-S-H) gels that are considered as the binding phase of cement paste. Cement-based materials are widely utilized in infrastructure.
