| Abstract: | Through controlling raw materials quality strictly and optimizing the mix proportion of the manufactured-sand concrete,C50 high strength concrete with manufactured-sand is made on the basis of the projection of the Hu-Rong West Expressway.The manufactured-sand concrete is successfully used in T-type prestressed concrete girder.The results of the loading test show that T-type girder made of manufactured-sand concrete has high load-carrying ability and anti-deformability. |
