| 中文摘要: |
| 在混凝土中分别单掺钢渣微粉、复掺钢渣微粉和矿渣粉，研究了其对混凝土工作性能、力学性能的影响，并通过X射线衍射（XRD）、扫描电镜(SEM)等现代测试手段分析了其对水泥水化影响的机理。实验确定了钢渣微粉、矿渣粉用做混凝土掺合料的最佳掺量：单掺钢渣微粉，其掺量不宜超过15%；钢渣微粉与矿渣粉具有很好的“互补效应”，当两者在胶凝材料中的总掺量达到30%，其中钢渣微粉掺量为15%时，能表现出较好的后期强度。 |

| In this experiment, steel slag micro-powder and slag were added respectively and together into concrete ,researches the influence on working performance of concrete, mechanical property and analyses cement hydration mechanism by X-ray diffraction (XRD), scanning electron microscope (SEM) and other modern phase testing means. It determined the optimum ratio of the steel slag micro-powder, slag used in concrete admixtures: The content of mixed steel slag micro-powder only should not be more than 15%; Steel slag powder and slag have good "complementary effect". When the total content in gelled material reaches 30% and the content of steel slag micro-powder is 15%，it can show good later strength. |
