摘要
以纯熟料水泥胶砂为基准,将矿渣粉与粉煤灰分别按照3种设计掺量以等质量替代水泥,研究了矿渣粉和粉煤灰对水泥胶砂力学性能的影响。试验结果表明,掺入矿渣粉可以提高胶砂的中、后期强度,掺入粉煤灰可以提高胶砂的早期抗裂性。
By using the cement binding sand of pure clinker as basic stuff and mixing slag and fly - ash with three equal designed amount instead of cement, research on the effect of slag and fly - ash on the mechanical property of the cement binding sand. The testing result indicates that adding slag powder can improve the early and late strengths of the binding sand and mixing fly - ash can improve the early crack resistance.
