摘　　要：无熟料高炉矿渣水泥混凝土的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。为此,以磷石膏作为激发剂配制无熟料高炉矿渣水泥混凝土后,通过抗压强度及其微观结构的测试探讨了其强度特性。结果表明,早期强度取决于钙矾石的生成量及其所形成的网状空间结构,后期强度取决于C-S-H水化物的生成量及其填充孔隙所形成的密实程度。The performance of non-clinker slag cement concrete depends on the alkalinity of water quench blast furnace slag,the chemical composition,the rate of vitrification and the type and quantity of excitant.Non-clinker cement concretes was prepared with phosphorus gypsum as the excitant.Its intensity characteristic was studied by compressive strength and microscopic structure.The results show that the intensity of the early strength depands on the amount and reticular spatial structure of ettringite,while the later intensity rests with the amount of C-S-H hydrate and the dense texture of the pores it fills.
