| Abstract: | This paper expresses a kind of CWP composite cement grout made up of water, cement, water glass as accelerant and phosphate as retarder. Among the phosphate used as retarder in CWP composite cement grout, ammonium dihydrogen phosphate (NH 4H 2PO 4) is the best one. In addition, CWP composite grout has unique performance in rheological property, plastic strength, stability and set strength. |
