低廉胶凝剂及其掺用外加剂强度试验

STRENGTH TEST OF CHEAPER CEMENTING MATERIALS AND ADDING ADMIXTURES

试验证明 :应用炉渣、黄土、石灰开发的低廉胶凝剂 ,可实现无水泥或少水泥胶结充填 ,保证胶充体强度 ;掺用外加剂对水泥有活化作用 ,可降低水泥用量 。

The test had proved that cheaper cementing materials,which is primarily made of slag,loess and lime,could realize cement filling with a bit or no cement,and ensure sthength of cement filling body.It also proved the adding admixtures could improve activity of cement,reduce amount of cement,and cut down costs of cement filling.
