The invention discloses an inorganic two-component grouting reinforcement material which comprises a group A material and a group B material; the material group A comprises the following components inparts by weight: 40-80 parts of sulphoaluminate cement, 5-20 parts of gypsum and 0.1-5 parts of additive group A; and the material group B comprises the following components: 60-90 parts of ordinaryPortland cement and 0.1-10 parts of additive group B. Compared with cement, the curing period is shorter, the mining efficiency is not delayed, polyurethane is not contained, the inorganic two-component grouting reinforcement material is mainly composed of inorganic materials, heat accumulation is not likely to be generated in the using process, safety is better, the solidified material is excellent in fracture resistance and compression resistance, and the filling and reinforcing requirements of coal seam gaps can be completely met.
本发明公开了一种无机双组份注浆加固材料，包括A组材料和B组材料；按重量份，所述A组材料的组分包括：硫铝酸盐水泥40～80、石膏5～20、A组外加剂0.1～5；所述B组材料的组分包括：普通硅酸盐水泥60～90、B组外加剂0.1～10。本发明比水泥的固化周期短，不会耽误开采效率，而且不含聚氨酯，主要由无机材料组成，在使用过程中，不易产生热量积聚，安全性更好，并且凝固后的材料抗折和抗压性能优良，完全能够满足煤层间隙的充填加固需要。
