Composite additive for grouting material and grouting material
The invention provides a composite additive for a grouting material and a grouting material. The composite additive comprises the following components in parts by weight: 1-3 parts of a polycarboxylate water reducer, 2-5 parts of bentonite, 2-4 parts of magnesium dihydrogen phosphate, 0.5-2 parts of polymeric aluminum sulfate, 2-6 parts of calcium sulfoaluminate, 0.5-1 part of cellulose ether and0.2-0.8 part of polyacrylonitrile fibers. The composite additive is added into cement slurry (especially silicate cement), so that the physical and mechanical properties of the cement slurry can be adjusted and changed, and effects of cement slurry such as rock surrounding, reinforcing, water intercepting, leakage stopping, geologic structure processing, and the like, are obviously improved.
本发明提供了一种用于注浆材料的复合添加剂及注浆材料，所述复合添加剂按重量份计包括如下组分：聚羧酸减水剂1份～3份、膨润土2份～5份、磷酸二氢镁2份～4份、聚合硫酸铝0.5份～2份、硫铝酸钙2份～6份、纤维素醚0.5份～1份和聚丙烯腈纤维0.2份～0.8份。本发明所述的复合添加剂加入到水泥类浆液(尤其是硅酸盐类水泥)中，能够调整和改变水泥浆液的物理力学性质，明显提高水泥类浆液围岩加固截水堵漏、地质构造治理工程等效果。
