Goaf grouting filling material and preparation method thereof
The invention relates to a goaf grouting and filling material and a preparation method thereof, and relates to the technical field of grouting and filling. The grouting filling material is mainly composed of industrial solid wastes such as slag, carbide slag and desulfurized gypsum, compared with cement, high-temperature calcination is not needed, the low-carbon and energy-saving effect advantages are obvious, the raw material components can react to generate a large number of expansive substances such as ettringite, and the problem that a traditional grouting material is large in shrinkage after being hardened is solved.
本发明涉及一种采空区注浆充填材料及其制备方法，涉及注浆充填技术领域。本发明的注浆充填材料主要由炉渣、电石渣、脱硫石膏等工业固废构成，与水泥相比，不需要高温煅烧，低碳节能效果优势明显，且原料组分可以反应生成大量钙矾石等膨胀性物质，解决了传统注浆材料硬化后收缩较大的问题。
