摘　　要：以广东省内某大型供水工程为背景,通过碳化深度测试、回弹法检测混凝土性能,并结合各种微观组成与结构表征方法(TG/DSC、XRD、SEM和EDS)对现场钻芯所取样品进行分析,从而综合评价现场混凝土表面碳化现状,以准确把握现场建筑物混凝土表面碳化情况,同时为国内同类工程混凝土表面碳化调查提供科学的参考依据。On the background of the large hydraulic project in Guangdong Province, carbonation degree test and kick - back compressive strength test are carried out to check the performance of concrete in the paper. Besides, all kinds of microanalysis methods（TG/DSC, XRD, SEM and EDS） are taken for the coresample to comprehensively analyze and evaluate the condition of concrete surface carbonation in the engineering. All the tests above not only exactly evaluate the condition of concrete surface Carbonation but also provide scientific lesson and reference for the similar project.
