Abstract

The invention discloses a quick-setting early-strength grouting material, and belongs to the technical field of grouting materials. The quick-setting early-strength grouting material comprises the following raw materials in percentage by mass: 75 to 90 parts of potland clinker, 3 to 10 parts of mineral slag, 5 to 15 parts of sulphate aluminium cement, 1 to 5 parts of silica fume, 0.5 to 4 parts of bentonite, 0.05 to 0.2 part of hydroxyethyl cellulose, 0.25 to 0.5 part of water reducing agent, 0.005 to 0.1 part of lithium carbonate, and 0.05 to 0.5 part of defoaming agent. The grouting material disclosed by the invention is mainly applied to grouting leakage plugging of a rock-soil layer, and in particular to the grouting leakage plugging engineering of water burst at the positions of a dam foundation and the like, and has the advantages of short setting time, high early strength, high construction performance, and good plugging performance.

Description

technical field

[0001] The invention relates to a fast-setting early-strength grouting material, which belongs to the technical field of grouting materials. Background technique

[0002] The grouting material is for the purpose of improving the foundation, and plays the role of filling the cracks and pores of the formation in the foundation and consolidating it. It is a solid formed by grout after a certain chemical or physical reaction. During the grouting process, it changes from liquid phase to solid phase and then to stone body, and is used to fill the cracks or pores in the formation.

[0003] During the construction of the dam foundation of the hydropower station, piping often occurs, and the water inflow is large, so the dam foundation needs to be blocked in time. The direct plugging effect of the commonly used cement slurry is not obvious, which is mainly because the cement solidification time is long, and the cement slurry is diluted by the water flow, which affect...
