To enhance the durability of the cement concrete of the bridge, C40 and C50 concretes with different raw materials have been made. A method of optimal selection method for raw materials has been put forward. For different raw materials from different plant, based on the orthogonal experimental design, certain raw materials groups are gained. By the same C40 and C50 concrete mix proportion but different raw materials groups, the specimens have been made for testing the performance of the compressive strength, carbonization and anti-chloride penetration. By range analysis, the best raw material group of the concrete with higher compressive strength, lower chloride penetration coefficient and lower carbonization depth has been selected.
