摘　　要：研究了钢渣复合掺合料配制C100混凝土的工作性能与力学性能,并采用ASTM C1202直流电量法和NEL法研究掺合料对混凝土抗氯离子渗透性能的影响。试验结果表明:钢渣复合掺合料能配制出工作性能好、28 d强度达100 MPa的混凝土,且其28 d抗氯离子渗透性能达到"很低"的评价等级,而且随着龄期的延长混凝土抗氯离子渗透性能达到"极低"的评价等级。At studies the workability and mechanical properties of C100 concrete maded by adding steel slag,and research the performance of concrete to anti-chloride ion penetration mixed with admixture by using ASTM C1202 charge passed method and NEL method.Result indicates that concrete mixed with steel slag can be prepared a good workability performance,strength of concrete reached 100 MPa and the performance of anti-chloride ion penetration reached a＂very low＂ evaluation criteria at the age of 28 days.The performance of concrete to anti-chloride ion penetration reached a＂very low＂ evaluation criteria along with the extension of age.
