摘　　要：分析了风冷高炉渣和水淬高炉渣的矿物组成和玻璃体含量。在此基础上,对比研究了风冷高炉渣复合体系水泥和水淬高炉渣复合体系水泥的净浆强度、水化产物的矿物相组成和微观形貌。结果表明,风冷高炉渣的主要组成为玻璃体和α'L-C2S,玻璃体含量为83.34%;水淬高炉渣的主要组成为玻璃体,玻璃体含量为96.79%。水化28d时,风冷高炉渣复合体系水泥与水淬高炉渣复合体系水泥相比,净浆抗压强度接近,水化产物的主要矿物相组成无明显差别。The mineral composition and noncrystal material content of air cooling blast furnace slag and water quenching blast furnace slag were analyzed. Based on this, the differences of the strength, mineral compositions and morphology of hydration production between two blended cement pastes, that mixed with air cooling blast furnace slag and water quenching blast furnace slag respectively, were studied. The results showed that the main compositions of air cooling blast furnace slag were noncrystal material and α＇L-C2S, and the noncrystal material content was 83.34%. The main composition of water quenching blast furnace slag was noncrystal material, and the noncrystal material content was 96.79%. At 28 days, the compressive strength of blended cement paste mixed with air cooling blast furnace slag was almost same with the blended cement paste mixed with water quenching blast furnace slag. And there were no obvious differences between the main mineral compositions of hydration production in the two blended cements.
