| Abstract: | Since the 1990s,cracking of concrete bridge has being a clearly trend,which directly threatening to the durability and security of bridge structures.This article collected relevant documents,then analyzed effects of fineness and composition of cement on the performance of concrete,and pointed out the differences between the current national cement standard and the performance requirements of concrete bridge.It also puts forward preliminary proposal for some parameters on fineness and composition of cement in bridge structures. |
