Abstract:A high speed railway construction unit requires C50 and the above concrete,must use the river sand as the fine aggregate to prepare the beam concrete.In this paper,the C55 continuous beam concrete is prepared by using the mechanism sand and river sand separately,and the durability of the concrete is detected,and then the feasibility of preparing C50 and the above concrete is discussed.
