摘　　要：以钢渣、脱硫石膏为主要原料,掺入适量矿渣和复掺少量激发剂,配制了无熟料钢渣水泥。试验结果表明所配制的无熟料钢渣水泥达到了42.5标号水泥的技术要求。探讨了矿渣掺量、激发剂复掺比例和脱硫石膏掺量对无熟料钢渣水泥强度和安定性的影响,以及配料的不同粉磨方式对无熟料钢渣水泥力学性能影响,通过微观分析进一步探究水化产物的结构和组成。With steel slag and FGD gypsum as the main raw material,adding appropriate amount slag and a little amount of of activator,a kind of clinker-free cement was made.The experimental results show that the clinkerfree cement reached the requirement of 42.5 grade cement.The slag dosage,activator mixed ratio and the desulfurization gypsum admixture on the effect of clinker-free cement strength and stability are discussed,as well as the impact of different grinding methods on the mechanical properties of steel slag clinker-free cement.The structure and composition of hydration products were further explored by microscopic analysis.X-ray and SEM were used to investigate the microcosmic mechanism of clinker-free cement.
