用硅质粉化岩做水泥混合材的试验

Study on using aged sandstone as an admixture of blended cement

采用化验室和生产试验,探讨用硅质粉化岩作水泥混合材对水泥物理性能的影响,结果表明:硅质粉化岩属于非活性混合材,其活性次于矿渣,优于石灰石和粉煤灰。

The effect of using aged sandstone as one of cement admixture on cement physical properties was discussed by laboratory and production test. The results showed that the aged sandstone was an inactive admixture; its activity was higher than limestone and fly ash, but less than slag.
