大理石粉对水泥物理力学性质影响试验研究

The Influence on Physical and Mechanical Properties of Marble Powder for Cement

大理石粉是一种重要的矿物掺合料,通过在水泥中掺加不同比例和粒径的大理石粉,来研究其对水泥强度、流动度、凝结时间和需水量的影响,发现大理石粉对水泥具有一定的减水效果、颗粒越细小其减水效果越明显,对凝结时间影响最敏感的指标为水粉比(W/P),对强度的影响比较明显。

Marble powder is an important mineral admixture.Adding marble powder to cement to produce various cement-based materials,which can not only improve the properties of cement-based materials,but also save cost,and become an important mineral admixture.By mixing the marble powder to cement,the marble powder cement setting time,water demand,fluidity and strength was studied.
