The invention relates to a high-strength anti-settling cement paste, which is composed of the following raw materials: 200-300 parts of cement, 150-200 parts of fine sand, 100-150 parts of fly ash, 10-30 parts of an anti-settling agent, 5-15 parts of a retarder, 5-10 parts of a fluid loss agent, 2-5 parts of glass fibers, 2-5 parts of a water reducing agent, 1-3 parts of a stabilizer, and 150-200parts of water. The anti-settling cement paste effectively prevents fine sand particles from aggregating with cement particles too early, the surface activity of the components is reduced, the relative distance between the components is adjusted to enable the components to be uniformly distributed in water, the components are not prone to layering in the curing process, fine sand is promoted to beuniformly dispersed in cement paste, fine sand particles and cement are dispersed and supported, the fine sand particles can be in a suspended state at the high temperature; and the technical effectof regulating the sedimentation stability of the cement paste at high temperature is achieved.
一种高强度抗沉降水泥浆，由以下各原料组成：水泥200‑300份，细砂150‑200份，粉煤灰100‑150份，抗沉降剂10‑30份，缓凝剂5‑15份，降失水剂5‑10份，玻璃纤维2‑5份，减水剂2‑5份，稳定剂1‑3份，水150‑200份，本发明抗沉降剂有效地防止了水泥浆细沙颗粒与水泥颗粒的过早聚集，降低他们表面活性，调整他们之间的相对间距使得其在水中均匀分布，在固化过程不易分层，促进细砂均匀分散在水泥浆中，对细沙颗粒和水泥起到分散和支撑作用，能够让细砂颗粒在高温下处于悬浮状态，达到了高温下调节水泥浆的沉降稳定性的技术效果。
