摘　　要：混凝土表层特性对混凝土结构耐久性有重要意义。文中从强度和耐久性两方面对表层混凝土性能评价方式进行阐述,论述了常见的检测方法的优缺点。表层混凝土的质量和耐久性息息相关,需要利用多种检测手段综合评价。应关注养护进程中表层混凝土性能的改变,实时监测构筑物从而有效预测结构物的耐久性。This paper expounds the evaluation methods of surface concrete performance from strength and durability,and the advantages and disadvantages of common detection methods were discussed.The quality of surface concrete is closely related to its durability,so it needs to be evaluated comprehensively by a variety of testing methods.The research of surface concrete performance should be paid more attention to the change of the structures along the period of curing,so as to improve the quality and effectively estimate the remaining life of existing structure.
