High-flow-state high-strength anti-shrinkage type flow-state soil and preparation method thereof
The invention discloses high-flow-state high-strength shrinkage-resistant fluid-state soil and a preparation method thereof, and belongs to the technical field of slurry solidification. The high-flow-state high-strength shrinkage-resistant fluid-state soil is prepared from the following raw materials in percentage by mass: 80 to 95 percent of slurry, 5 to 20 percent of a curing agent and 0.05 to 0.1 percent of slow-release water replenishing microbeads, the curing agent comprises the following raw materials in percentage by mass: 40-70% of mineral powder, 6-15% of cement, 3-10% of lime, 4-10% of fly ash, 4-8% of red mud, 5-15% of anhydrous sodium sulphate, 4-8% of calcium chloride and 0.5-3% of expanded microspheres. The high-flow-state high-strength shrinkage-resistant fluid-state soil has the advantages of high fluidity, high strength, low shrinkage and the like, the technical problems that existing fluid-state solidified soil is large in shrinkage, the fluidity and the strength are not matched and the like are solved, and the practical engineering requirements of the current fluid-state solidified soil can be met.
本发明公开了一种高流态高强抗缩型流态土及其制备方法，属于泥浆固化技术领域。本发明的高流态高强抗缩型流态土，以质量百分比计，包括以下原料：泥浆80～95％、固化剂5～20％和缓释补水微珠0.05～0.1％；所述固化剂，以质量百分比计，包括以下原料：矿粉40～70％、水泥6～15％、石灰3～10％、粉煤灰4～10％、赤泥4～8％、元明粉5～15％、氯化钙4～8％和膨胀微珠0.5～3％。本发明的高流态高强抗缩型流态土具有高流动性、高强度、低收缩等优点，克服了现有流态固化土收缩大，流动性与强度不匹配等技术难题，可以满足当前流态固化土的工程实用需求。
