提高碾压混凝土抗裂能力的试验研究

The experiment studies to increase the resist-craze capability of rolled concrete

通过试验分析了外掺单矿C2S和C4AF矿物成分和用活性掺合料(粉煤灰F、硅灰SF、氧化镁MgO)等量取代水泥(C)和用非活性掺合料(橡胶粉X)等体积取代部分标准砂(S)对水泥脆性系数的影响。

Generally,the brittleness index of cement is affected by accessory ingredient,such as C2S,C4AF.In this thesis,the influence factors upon brittleness index of cement are investigated by experiments.
