Title:
PREPARATION METHOD FOR GROUTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/015509
Kind Code:
A1
Abstract:
A preparation method for a grouting material, wherein 80-12 parts of magnesium phosphate cement, 4-15 parts of an additive, 10-15 parts of an admixture and 50-100 parts of an aggregate are used as a grouting material; by means of reasonable proportional design, the amount of magnesium phosphate cement may be effectively reduced so that the powder content in the aggregate is controlled and costs are reduced. The grouting material is suitable for geological conditions in which engineering is complex, such as tunnel engineering, slope treatment engineering, mining engineering, and urban underground spaces, and the effect of the grouting material on surrounding rock reinforcement and anti-seepage and plugging in the geological conditions in which engineering is complex is improved.
