Expansive slurry for rock mass grouting reinforcement and preparation method thereof
The invention relates to expansive slurry for rock mass grouting reinforcement, a formula of the expansive slurry for rock mass grouting reinforcement and a preparation method of the expansive slurry. The expansive slurry for rock mass grouting reinforcement is characterized by comprising Portland cement, an expanding agent, water glass, a defoaming agent, an accelerator and water. The concrete is prepared from the following components in parts by mass: 50 to 75 parts of Portland cement, 4.5 to 13.5 parts of expanding agent, 5 to 15 parts of water glass, 0.07 to 0.105 part of defoaming agent, 1.5 to 2.25 parts of accelerator and 35 to 52.5 parts of water. The preparation method comprises the following steps of: mixing the components in parts by mass: 50 to 75 parts of Portland cement, 4.5 to 13.5 parts of expanding agent, 5 to 15 parts of water glass, 0.07 to 0.105 part of defoaming agent, 1.5 to 2.25 parts of accelerator and 35 to 52.5 parts of water. Slurry is prepared according to the formula, and the slurry is high in compactness, high in strength, short in setting time, short in expansion development time, high in volume expansion rate and high in expansion stress. The slurry is injected into the weak surface of the rock mass, so that the friction force and the binding power of the weak surface can be well improved, and the overall strength and the stability of the broken rock mass are further improved.
本发明涉及一种岩体注浆加固用膨胀型浆体及一种岩体注浆加固用膨胀型浆体配方及其制备方法，其特征在于包括：硅酸盐水泥、膨胀剂、水玻璃、消泡剂、速凝剂、水。所述硅酸盐水泥、膨胀剂、水玻璃、消泡剂、速凝剂、水的配比质量份为：硅酸盐水泥50～75份、膨胀剂4.5～13.5份、水玻璃5～15份、消泡剂0.07～0.105份、速凝剂1.5～2.25份、水35～52.5份。本发明通过其配方制作成浆体，浆体密实度高、强度大、凝结时间短、膨胀发育时间短、体积膨胀率大、膨胀应力强。通过向岩体弱面内注入此浆体，能很好地提高弱面的摩擦力和粘结力，进而提升破碎岩体的整体强度和稳定性。
