Cement base inorganic waterproof grouting material

Abstract

The invention discloses a cement base inorganic waterproof grouting material, which is prepared by uniformly mixing the following raw materials in percentage by weight: 30.0 percent of ordinary Portland cement, 20.0 percent of high-alumina cement, 12.0 percent of fly ash, 6.0 percent of gypsum powder, 2.0 percent of lime powder, 30.0 percent of quartz sand and 2.31 percent of functional additive, wherein the functional additive is prepared by mixing the following raw materials in percentage by weight: 0.7 percent of naphthalin water reducing agent, 0.75 percent of sodium aluminate, 0.25 percent of anhydrous sodium sulfate, 0.3 percent of sodium metasilicate, 0.3 percent of hydrophobic powder and 0.01 percent of HPMC; and the weight error for taking all the raw materials is controlled to be + / -5 percent. The inorganic waterproof grouting material is suitable for leak stoppage and solidification of waterproof work and reinforcement projects such as dame seepage, piping water leakage, road slab breaking, mile collapse, equipment base anchoring, column stabilization and the like, and has the advantages of high water resistance, convenient construction, simple manufacturing and low cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement-based inorganic waterproof grouting material. Background technique [0002] At present, the grouting materials used in the field of building waterproofing are mostly polymer resin materials such as epoxy resin and polyurethane. This material has high grade and good performance, but it is expensive and not easy to operate. Although cement-based inorganic grouting materials are used, they have different formulations and poor quality and performance, so they have not been popularized. Contents of the invention [0003] In view of this, the object of the present invention is to provide a cement-based inorganic waterproof grouting material, which can improve the waterproof performance of the waterproof grouting material, reduce the cost of the waterproof grouting material, and improve its construction operation convenience and construction efficiency.
