Composite pile premixed flow-state solidified soil slurry and preparation method thereof
The invention discloses premixed fluid-state solidified soil slurry for a composite pile and a preparation method of the premixed fluid-state solidified soil slurry. The premixed fluid-state solidified soil slurry for the composite pile is prepared from the following raw materials in parts by weight: 100-150 parts of cement; 200 to 220 parts by weight of fine sand; 20-30 parts by weight of red mud; 5-10 parts by weight of calcium oxide; 0.5 to 1.2 parts by weight of nano zinc oxide modified epoxy resin; and 70-90 parts by weight of water. The expansion degree of the premixed fluid-state solidified soil slurry of the composite pile is 170 mm or above, the 28d unconfined compressive strength can reach 10 MPa or above, and the strength loss rate of five freezing and thawing cycles can reach 16% or below.
本申请公开了一种复合桩预拌流态固化土浆及其制备方法，所述复合桩预拌流态固化土浆由包括以下重量份的原料制备得到：水泥100‑150重量份；细砂200‑220重量份；赤泥20‑30重量份；氧化钙5‑10重量份；纳米氧化锌改性环氧树脂0.5‑1.2重量份；水70‑90重量份。该复合桩预拌流态固化土浆扩展度在170mm及以上，28d无侧限抗压强度可以达到10MPa以上，5次冻融循环强度损失率可以达到16%以下。
