Silica fume modified double-liquid grouting material and preparation method thereof
The invention discloses a silica fume modified double-liquid grouting material which comprises a liquid A and a liquid B. The volume ratio of the liquid A to the liquid B is 1: 1-2.5: 1. The silica fume modified double-liquid grouting material comprises the following raw materials: ordinary Portland cement, water, water glass, silica fume and a water reducing agent. According to the silica fume modified double-liquid grouting material and the preparation method thereof, a certain amount of silica fume and a water reducing agent are introduced on the basis of a cement and water glass double-liquid grouting material to modify the cement and water glass double-liquid grouting material, an orthogonal experiment is carried out in combination with related influence factors of basic characteristics of grout to obtain a better proportion, and the silica fume modified double-liquid grouting material is prepared; therefore, the silica fume modified double-liquid grouting material has excellent mechanical properties and durability, the optimal mix proportion is determined through an orthogonal experiment and a trend chart of each factor on evaluation indexes, and the feasibility of the silica fume modified double-liquid grouting material is analyzed from a theoretical level. Therefore, the grouting material has the advantages of being environmentally friendly, good in stability, controllable in setting time, high in slurry stone body strength in different maintenance stages, and excellent in water corrosion resistance and impermeability, and has a good anti-seepage and leaking stoppage effect.
