| 中文摘要: |
| 研制了一种以无机聚合物（水玻璃）为速凝剂，以磷酸盐为缓凝剂配制而成的CWP水泥复合浆液。在该复合浆液中，用磷酸二氢铵作缓凝剂效果最好。CWP复合浆液在流变性，塑性强度，稳定性和结石强度上具有优良的性能。 |
| 英文摘要: |
| 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. |
