Grouting material for reinforcing silty-fine sand layer and preparation method thereof
The invention relates to the technical field of building materials, in particular to a grouting material for reinforcing a silty-fine sand layer and a preparation method thereof.The grouting material is prepared by mixing 35-45 parts of water glass and 10-30 parts of ethyl acetate emulsion, the viscosity of the ethyl acetate emulsion is 7-15 mPa.s, and the particle size of ethyl acetate is smaller than or equal to 0.75 micron. The grouting material prepared by mixing the ethyl acetate emulsion with specific viscosity and specific particle size and a specific amount of water glass has the characteristics of low initial viscosity, high fluidity and stable diffusion radius, the curing time is proper, and the solidified grouting material has excellent mechanical properties and can meet the requirements of the silty-fine sand layer reinforcement construction process on the grouting material.
本发明涉及建筑材料技术领域，尤其涉及一种粉细砂层加固用注浆材料及其制备方法，该注浆材料由35～45份水玻璃和10～30份乙酸乙酯乳液混合制成，其中乙酸乙酯乳液的粘度为7～15mPa·s，乙酸乙酯粒度≤0.75μm。特定粘度、特定粒度的乙酸乙酯乳液与特定用量的水玻璃混合制成的注浆材料，具有初始粘度低、流动性强、扩散半径稳定的特点，并且固化时间适宜，凝固后的注浆材料力学性能优良，能契合粉细砂层加固施工过程对注浆材料的需求。
