摘要
为研究不同矿渣、粉煤灰和不同细度的混合料对水泥力学性能的影响,并分析不同混合材对水泥活性指数的影响,确定了混合材对水泥性能的影响机理。结果表明:矿渣中的CaO和MgO成分是导致矿渣对水泥性能及活性影响的直接原因;混合材主要起到填充作用,其细度对水泥的早期、后期强度没有明显的改善作用;较粗的活性混合材对提高水泥活性指数和抗压性能具有更明显的效果。
The mechanism of how admixture affects the mechanical properties of cement was determined by testing with different slag,fly ash and mixture with different fineness and analyzing the impact of admixture on the activity index of cement.The results show that CaO and MgO in the slag directly cause the impact on cement＇s properties and its activity index;the fineness of the admixture has little impact on the strength of cement;coarse active admixture improves the activity index and compressive strength more obviously.
