This research is carried out under the instruction of pump concrete,mixing with recycled coarse aggregate,to get a conclusion from the durability test against the port corrosion environment.The experiment shows that it is possible to improve the durability of C30～C40 concrete after cement is partly replaced by fly-ash and mixed with specified admixture,so as to fulfill the basic requirement of commercial concrete.It could bring a reasonable orientation to use recycled aggregate concrete for civil structure in port environment,and to provide conditions for the sustainable development of economy and environment.
