水泥强度对矿渣微粉活性的影响

The effect of cement of different strength on activity behavior of grounded furnace slay

采用不同强度值的水泥,用不同生产厂家的不同比表面积的矿渣微粉,等量取代水泥,研究矿渣微粉的活性指数,通过在水泥砂浆和混凝土中的强度及其它性能的研究表明,水泥的早期强度值越高,矿渣微粉的活性指数越大。另外,可使混凝土的强度和耐久性能明显提高。

Adopting cement of different strength and grounded furnace slay with different specific surface areas, the index of activity of grounded furnace slay is studied when they institute cement in equal quantity. It is indicated that the index of activity of grounded furnace slay is raised with increasing of early strength of cement, and the strength and durability of concrete are increased remarkably.
