Solid waste green grouting material for reinforcing cracks of mining bottom plate and preparation method of solid waste green grouting material
The invention discloses a solid waste green grouting material for reinforcing cracks of a mining floor. The grouting material is prepared from cement, fly ash, clay, a foaming agent, a water reducing agent and water. The use amount of the foaming agent is 0.1-5% of the total mass of the cement, the fly ash and the clay; the use amount of the water reducing agent is 0.1-2% of the total mass of the cement, the fly ash and the clay; the ratio of the mass of the water to the total mass of the cement, the fly ash and the clay is 0.5-1. The solid waste green grouting material provided by the invention is a non-Newtonian fluid which is a grouting raw material with a small particle size, good applicability and a stable structure, and has good impermeability and viscosity time-varying property, after grout is injected into a crack of a bottom plate, internal pores in a grouting stone body within a grout diffusion range can be dense, the stone rate is high, the strength and the impermeability are remarkably improved, and the service life of the grouting stone body is prolonged. The anti-seepage reinforcing agent has a good anti-seepage reinforcing effect on fractures of a bottom plate containing confined water, is safe, pollution-free and low in cost, consumes the coal ash stock, and improves the utilization efficiency of solid waste products.
本发明公开一种矿用底板裂隙加固的固废绿色注浆材料，该注浆材料是由水泥、粉煤灰、黏土、发泡剂、减水剂和水制备而成；发泡剂的用量为水泥、粉煤灰和黏土总质量的0.1‑5％；减水剂的用量为水泥、粉煤灰和黏土总质量的0.1‑2％；水的质量与水泥、粉煤灰和黏土总质量的比值为0.5‑1。本发明提出的固废绿色注浆材料是一种注浆原料粒径微小、适用性好、结构稳定的非牛顿流体，具有良好的抗渗性和粘度时变性，浆液注入底板裂隙后可使浆液扩散范围内注浆结石体内部孔隙密实，结石率高，强度与抗渗性能显著提高，对含承压水底板裂隙具有良好的防渗加固效果，安全无污染，成本低，又消耗了粉煤灰存量，提高了固废产物的利用效率。
