Pressure grouting material and application thereof
The invention provides a pressure grouting material as well as a preparation method and application thereof, and the grouting material comprises the following raw material components in parts by weight: 97.0-98.5 parts of a composite mineral material, 0.2-0.3 part of a powder water reducing agent, 0.2-0.4 part of a plastic expanding agent, 0.1-0.3 part of a defoaming agent and 1.0-2.0 parts of an early strength agent. The composite mineral material comprises the following raw material components in parts by weight: 25-30 parts of semicoke slag, 40-45 parts of blast furnace slag, 8-10 parts of desulfurized gypsum and 20-25 parts of Portland cement clinker, and the total parts by weight of all the components is 100. The pressure grouting material has excellent flow characteristics, good gelling characteristics and sulfate absorption characteristics, and can absorb free sulfate ions in the environment before and after hardening and participate in self hydration reaction, so that the content of sulfate in the environment is effectively reduced, and the damage of sulfate to an original base layer is reduced. The pressure grouting material is suitable for grouting repair of highway base cracks and other grouting projects, and is especially suitable for repair of soluble salt enriched base cracks in salinized soil areas.
本发明提供一种压力注浆材料、制备方法及应用，注浆材料包括以下原料组分：以重量份数计，复合矿物材料97.0～98.5份、粉体减水剂0.2～0.3份、塑性膨胀剂0.2～0.4份、消泡剂0.1～0.3份、早强剂1.0～2.0份。复合矿物材料包括以下原料组分，以重量份数计半焦渣25～30份，高炉矿渣40～45份，脱硫石膏8～10份，硅酸盐水泥熟料20～25份，各组分的合计重量份数为100份。压力注浆材料具有优异的流动特性和良好胶凝特性，并具有吸收硫酸盐的特性，压力注浆材料在硬化前后均可吸收环境中的游离态硫酸根离子，参与自身水化反应，有效降低环境硫酸盐含量，减少硫酸盐对原基层的损伤。压力注浆材料适用于公路基层裂缝注浆修复以及其他的注浆工程，尤其适用于盐渍土地区易溶盐富集基层裂缝修复。
