High-strength sleeve grouting material
The invention is applicable to the field of grouting materials, and provides a high-strength sleeve grouting material, which is prepared from the following components in parts by weight: 400 to 500 parts of ordinary silicon 525 cement, 20 to 50 parts of sulfur aluminum cement, 10 to 30 parts of mineral admixture, 10 to 30 parts of microbeads, 400 to 500 parts of medium-fine sand, 4 to 8 parts of powder water reducing agent, 0.1 to 0.5 part of plastic expanding agent, 0.1 to 0.4 part of a powder defoaming agent, 0.1 to 0.5 part of lithium sulfate, 0.01 to 0.3 part of rheological agent and 0.2 to 1 part of a reinforcing agent. The product has the advantages of low viscosity, stable system, difficult bleeding, early strength and high strength, the 28-day compressive strength is higher than 100MPa, which is higher than the 85MPa technical index generally required by the standard, the application range is wider, the used raw materials are easy to obtain, and the production process is simple.
本发明适用于灌浆料领域，提供了一种高强度套筒灌浆料，各组分按重量份数包括：普硅525水泥400‑500份、硫铝水泥20‑50份、矿物掺合料10‑30份、微珠10‑30份、中细砂400‑500份、粉体减水剂4‑8份、塑性膨胀剂0.1‑0.5份、粉体消泡剂0.1‑0.4份、硫酸锂0.1‑0.5份、流变剂0.01‑0.3份和增强剂0.2‑1份。本发明产品粘度低，体系稳定不易泌水，早强高强，28天抗压强度高于100MPa，高于规范标准一般要求的85MPa技术指标，应用范围更广，且所用原料容易获得，生产工艺简单。
