摘要
把不同的石膏加入同种熟料中,在不同的粉磨设备中磨制成比表面积不同的水泥,再在不同温度下将水泥配制成同等级泵送混凝土,测定其初始、1h、2h的坍落度和扩展度,以及3d、7d和28d抗压强度,以此来探讨不同水泥对流动混凝土性能的影响。
The cement with different specific surface area were prepared in dif ferent grinding device by adding variable gypsum into the same kind of clinker, then the cement was grinded to prepare the same class pumped concrete under diff erent temperature. The slump and extension of concrete of initial, 1h, 2h and it s compressive strength of 3d, 7d , 28d were determined, so the effect of cement admixed with different gypsum on performance of concrete was discussed based on above.
