Material for reinforcing mine
The invention relates to a material for reinforcing a mine. The material comprises a component A, a component B and a composition of cement, wherein the component A is a compound in a formula I; the component B is an assistant; cement is ordinary portland cement; the assistant is prepared from the following raw materials in parts by weight: 0.6-1.0 part of p-toluenesulfonic acid, 0.8-1.3 parts of phosphoric acid, 0.5-1.0 part of hydrochloric acid and 0.1 part of ethylene glycol; the mass percentage of the hydrochloric acid is 37%; the mass percentage of the phosphoric acid is 98%; the component A and the component B are mixed at the mass ratio of 1 to 1 when the material is used; and the portland cement is 100 parts by weight. The composition disclosed by the invention has good effects in seepage rate, shrinkage rate and hardness.
