摘要
通过对木钙砂浆的试验研究，解决了高标号水泥配制低标号砂浆时，砂浆强度严重超强与水泥浪费的问题。
In this paper, the experimental research of the sand grout of ca－lignosulphonate orFDN anti－water is studied. When we make up low－grade sand grOut with high－grade cement, the problems that cement mortar seriously exceeds the strength limit and wastes alot of cement are solved.
