【Abstract】 Studying the adherence performance and engineering application of new on old concre e has been the key problem of repairing concrete structure. The research of new and old concrete both at home and abroad has been summarized in this paper. And the present research situation of adherence of rew -to - old concrete is introduced from four aspects: interfacial treatment, roughness, binder and nev concrete . The self - compact concrete used in repairing structure as new concrete is also presented in this paper.更多还原
