摘　　要：在研究不同钢渣掺量胶凝体系稳定性的基础上,以40%的钢渣粉掺加15%矿渣粉、5%硅灰粉,采用自配复合激发剂成功地制备出早期抗折强度、抗压强度达到4.5MPa、18.8MPa且满足42.5强度等级的复合胶凝材料,通过其孔隙率及微观结构测试分析表明:钢渣复合胶凝材料水化产物致密,孔隙率低,后期抗压强度、抗折强度发展较好。Based on study of stability of cementitious system with different steel slag admixture, used steel slag40 %, slag 15 % and silica fume 5 %, added with self-made compound excitant the complex binding material was successfully prepared to meet the 42. 5 strength composite cementitious material,which flexural and compressive strengths attained 4.5MPa and 18. 8 MPa in the early stage. Test result of the porosity and the microcosmic structure showed that the compo- sition of complex binding material had compact structure of hydration products, a low porosity and compressive strength and flexural strength were developed better in later.
