A coal ash-cement mortar grouting material
A coal ash-cement mortar grouting material is disclosed. The grouting material comprises coal ash, cement and water, wherein the weight ratio of the coal ash to the cement is 10-50:90-50, and the water cement ratio is 1:0.5-1:0.75. When the doping percent of the coal ash is less than 30% and the water cement ratio is 0.5-0.75, the grouting effects of the grouting material are good. In grouting processes, coal ash doping amounts of different ratios can be selected according to the size of water inflow of drill holes and rock stratum groutability differences to achieve corresponding grouting effects.
