摘　　要：该文针对机制砂生产过程中产生的石粉和肯尼亚水泥价格较高的问题,研究采用石粉替代部分水泥配制砌筑砂浆,从岩石粉和粉煤灰复合比例、岩石粉掺量、纤维素醚掺量和掺加减水剂的角度,研究了采用石粉替代部分水泥配制砌筑砂浆。In this article,in view of stone powder produced in the production of manufactured sand and the high price of Kenya cement,the masonry mortar is prepared by using stone powder instead of part of cement.From the perspectives of the composite ratio of rock powder and fly ash,the mixing content of rock powder and cellulose ether and the addition of water reducer,this paper studied the masonry mortar prepared by using stone powder instead of part of cement.

关 键 词：岩石粉 砌筑砂浆 纤维素醚 减水剂
