Mixed slurry for foundation treatment engineering, and preparation method thereof
The invention discloses mixed slurry for foundation treatment engineering, and a preparation method of the mixed slurry, wherein the mixed slurry comprises 30-40 parts of lightweight cement, 20-30 parts of modified slag powder, 15-20 parts of wollastonite powder, 10-15 parts of sodium silicate, 10-15 parts of potassium silicate, 8-12 parts of an additive, 6-8 parts of sawdust and the balance of clear water. According to the invention, the lightweight cement can enable slurry to meet the requirements of density, strength and fluidity, the modified slag powder can improve the grinding property and miscibility of the slag powder and improve the pressure resistance of the slurry, the wollastonite powder can improve the acid and alkali resistance and strength of the slurry and improve the hygroscopicity of the slurry after application, and the mixture of sodium silicate and potassium silicate is used as a coagulant to shorten the setting time of the mixed slurry during use and enhance the compressive strength, so that the mixed slurry for foundation treatment engineering can meet the requirements on density, strength and flowability on the basis of reducing self-weight load, and the compressive strength of the slurry is improved. The preparation method has the same advantages.
本发明公开了地基处理工程用混合浆液及其制备方法，该混合浆液包括轻质水泥30份至40份、改性矿渣粉20份至30份、硅灰石粉15份至20份、硅酸钠10份至15份、硅酸钾10份至15份、添加剂8份至12份、木屑6份至8份，余量为清水，这种轻质水泥能使浆液满足密度、强度和流动性的要求，改性矿渣粉能改善矿渣粉研磨性和混溶性能，提高浆液抗压性，硅灰石粉能提高浆液抗酸碱性和强度，改善浆液施用后的吸湿性，以硅酸钠和硅酸钾的混合物作为促凝剂，能缩短混合浆液在使用中的凝结时间，增强浆液抗压强度，因此上述地基处理工程用混合浆液能在减少自重荷载的基础上，满足密度、强度和流动性的要求，提高浆液的抗压强度。上述制备方法具有同样的优点。
