摘要
粉煤灰作为水泥混合材料已普遍使用,它不仅可以降低水泥的生产成本,而且改善水泥的使用和施工性能;本试验采用掺加50%以上的粉煤灰作为混合材料,掺加少量矿渣微粉和其他组分的外加剂,开发具有低水化热和微膨胀等特性的水泥,该水泥可用于公路基层,也可用于水利基本建设,改善工程施工性能和制品的使用寿命。
Fly ash, as mixing material of cement, has been widely used. It can not only reduce the production cost of cement, but also improve the using and construction performance of cement. The cement of low hydration heat and expansion is developed which over 50% fly ash as mixing material has been mixed, as well as small amount of slag powder and other additives. This kind of cement may be used in highway base and water conservancy, which can change the construction performance of project and lifetime.
