摘要
研究了细粉煤灰对低品质水泥性能的改善效果。结果显示,利用细粉煤灰与低品质水泥组成的复合胶凝材料能够较容易地配制出满足设计要求的混凝土。由复合胶凝材料配制的混凝土在满足抗压强度的同时,还具有较高的劈裂抗拉强度及密实度,后期性能改善的幅度更加明显。
The improving influence of fine fly ash on the properties of low-quality cement is investigated. The results show that concrete which meets the design requirement can be easily produced by complex binder material of low-quality cement and fine fly ash. The concrete produced by complex binder material can meet the design compressive strength, and it also has higher splitting tensile strength and higher density. Meanwhile, the late-age performance of concrete produced by complex binder material is significantly improved.
