Abstract :In Northwest ,groundwater and subsoil of many projects are highly corrosive ,moreover ,the annual
temperature is largely different due to the climate. So the higher requirements are put forward to the corrosion
resistance of concrete. A series of corrosion resistance experiments were made to study the corrosion resistance of five
kinds of concretes. The results indicated that the corrosion resistance of concrete C30 and C40 with ordinary Portland
cement P ·O 42. 5 and mineral admixtures was better than that of concrete C25 with high su
