Abstract

In order to utilize local materials and save project costs, sandstone gravel from Datong County of Qinghai Province was used as coarse concrete aggregate to prepare C40 bridge structural concrete in cold areas, and the durability of sandstone gravel concrete was studied. The results show that the sandstone gravel C40 concrete and basalt gravel C40 concrete are very dense, and the impermeability grade is higher than P30, which can meet the requirements of anti-impermeability of engineering projects. The electric flux of sandstone gravel concrete is less than 1 200 C, which can meet the requirement of a 100-year design life of the concrete structure. The 28 d carbonization depth of sandstone gravel concrete is not obvious, and it has good carbonization resistance. The evaluation grade of sulfate erosion resistance of sandstone gravel concrete is greater than KS120. It also meets the requirements of freezing resistance of concrete in a Class II environment. The sandstone gravel can be used to prepare C40 concrete for structures in cold areas.
