Design on the concrete structure durability of the relocation of Shougang and the steel project construction of Caofeidian

The relocation of Shougang and the steel project construction of Caofeidian is a national major project, according to the working life of design, the environmental classification and their exposure classes, we must consider the concrete structural durability in various ways, such as the forms of concrete structures, texture measures, the concrete materials and so on. The paper has discussed the basic design regulations, the forms of concrete structures and texture measures as well as the technical requirement of concrete materials, it is example with the concrete structures of the major projects, has analyzed the effect of the durability design for the actual concrete material.
