摘　　要：本文介绍了磨细矿渣高性能混凝土在工程实际应用中的施工状况和性能检测结果。磨细矿渣高性能混凝土适宜配制C30～C60强度等级的海工混凝土 ,具备优越的抗氯离子侵蚀能力 ,与普通混凝土相比 ,最少可延长使用寿命 3～ 4倍以上。? In this paper,the laboratory researches on GGS high performance concrete have been successfully applied to the new coal quay project in the south of Tianjin port.The showcase's completion and its properties results in site show that GGS high performance concrete is a marine concrete with superior properties,and applicable to mixing marine concrete of strength C30～C60.GGS high performance concrete has superior capability of resistance to chloride ion attack,which diffusion coefficient of chloride ion is only 25% of that of ordinary concrete,and life span should be extended more than 3～4 times.Whereas,its price of 1m\+3 is only increased 35～40 RMB yuan than that of ordinary concrete,but the cost of resistance to concrete surface erosion should be saved.The tests in site indicate that GGS high performance concrete is valuable in marine constructions.
