摘　　要：无熟料水泥混凝土(NSC)是利用水淬高炉矿渣和激发剂在常温下经配料、研磨而成的新型水泥来配制的混凝土,其性能取决于水淬高炉矿渣的碱度、化学成分、玻璃化率以及激发剂的种类和数量,因而对Cl-的抗渗和固化有其独特的性能。为此,以石膏和石灰作为激发剂配制NSC后,用电通量法等科学手段进行了对Cl-离子的抗渗和固化实验。结果表明:NSC的效果远远超过普通混凝土和矿渣水泥。Non -clinker slag cement concrete （NSC） is prepared by water quench blast furnace slag and ex- citant by grinding and ingredients at room temperature. The performance of non - clinker slag cement concrete de- pends on the alkalinity of water quench blast furnace slag, the chemical composition, the rate of vitrification and the type and quantity of excitant, thus the impermeability and solidify characteristics for Cl^- of non - clinker slag cement concretes are different from ordinary concrete. After non -clinker slag cement concretes was prepared with phosphorus gypsum as the excitant, the impermeability and solidification experiments for Cl^- by the electric flux method was done. The results show that, NSC＇s solidification effect is far mote than ordinary concrete （OPC） and slag cement （BSC）.
