Micro-nano bubble-containing grouting material for red-layer soft rock roadbed grouting
The invention relates to a grouting material containing micro-nano bubbles for grouting a red-layer soft rock roadbed. The grouting material comprises Portland cement, carbon fibers, gamma-propyltrimethoxysilane, octadecyl primary amine, silicon dioxide, potassium methyl silicate, glass fibers and water. The content of the micro-nano bubbles in the grouting material is 0.1%-5.0%. According to the grouting material, the initial setting time and the final setting time of the grouting material are rapidly shortened, and the 28-day compressive strength is greatly improved. According to the grouting material disclosed by the invention, the viscosity of the grouting slurry is reduced by utilizing the micro-nano bubbles, so that the grouting resistance is reduced, the fluidity of the grouting slurry is favorably improved, and the grouting slurry is more easily injected into rock soil.
一种红层软岩路基注浆用含有微纳米气泡的注浆材料，所述注浆材料包括有硅酸盐水泥、碳纤维、γ‑丙基三甲氧基硅烷、十八烷基伯胺、二氧化硅、甲基硅酸钾、玻璃纤维、水；注浆材料中微纳米气泡含量为0.1%‑5.0%。本发明注浆材料，注浆材料的初凝时间和终凝时间快速的缩短，28天抗压强度较大幅度的提高。本发明注浆材料，利用微纳米气泡减少注浆浆液的粘性，从而降低了注浆的阻力，有助于提高注浆浆液的流动性，使其更容易注入岩土中。
