Coal gangue roadway spraying material and preparation method thereof
The invention relates to the technical field of roadway spraying materials, and provides a coal gangue roadway spraying material and a preparation method thereof. Sequentially mixing the powder-removed coal gangue, sand, slag powder, fly ash, silica fume, gypsum, cement, calcium chloride, copper oxide, barium sulfate, fibers and an additive to obtain a solid raw material; and mixing the solid raw material with an alkaline activator, a polycarboxylate superplasticizer and water, and curing to obtain the coal gangue roadway spraying material. The preparation technology is simple, the production efficiency is high, operation is easy and stable, control is convenient, and automatic operation is easy to achieve. The obtained coal gangue roadway spraying material is low in cost, carbon emission is reduced, the problem of accumulation of a large amount of industrial solid waste is solved, the resource utilization rate is increased, and the current green and low-carbon call is met; the coal gangue and the cementing material are tightly combined, the 3d strength of the coal gangue roadway spraying material reaches 22.9 MPa, the 7d strength reaches 35.5 MPa, and the 28d strength reaches 50.1 MPa.
本发明涉及巷道喷料技术领域，本发明提供了一种煤矸石巷道喷料及其制备方法。将去粉煤矸石、砂子、矿渣粉、粉煤灰、硅灰、石膏、水泥、氯化钙、氧化铜、硫酸钡、纤维和添加剂依次混合，得到固体原料；将固体原料与碱性激发剂、聚羧酸减水剂和水混合，养护后得到所述的煤矸石巷道喷料。本发明的制备工艺简单，生产效率高，操作简单稳定，控制方便，容易实现自动化作业。本发明得到的煤矸石巷道喷料成本低，减少了碳排放量，解决了大量工业固废堆积问题，提升了资源利用率，符合当前绿色低碳的号召；煤矸石和胶凝材料结合紧密，煤矸石巷道喷料3d强度达到22.9MPa，7d强度达到35.5MPa，28d强度达到50.1MPa。
