Abstract

The invention provides a sprayable, waterproof, anticorrosive and erosion-resistant high-strength mortar and a using method thereof, and belongs to the technical field of building materials. The sprayable, waterproof, anticorrosive and erosion-resistant high-strength mortar comprises, by mass, 300-380 parts of a Portland cement clinker, 22-45 parts of silica fume, 20-50 parts of ultrafine mineralslag powder, 450-600 parts of active steel slag, 0.2-0.6 part of a dispersant, 0.5-1.2 parts of an antifoaming agent, 1-2 parts of a stable thickening agent, 0.01-0.05 part of hydroxyethyl cellulose ether, 5-20 parts of waterproof rubber powder and 1-3 parts of a water repellent. The sprayable, waterproof, anticorrosive and erosion-resistant high-strength mortar has the advantages of high impermeability, high compressive strength and bonding strength, excellent alkali resistance, excellent sulfate corrosion resistance, excellent hydrophobicity, low shrinkage rate and good volume stability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sprayable waterproof, anti-corrosion, and erosion-resistant high-strength mortar and a method for using the same. Background technique [0002] With the improvement of people's requirements for the quality of construction projects, the waterproofing of wall facades and wet base surfaces has attracted more and more attention from the construction industry. On the other hand, since the leakage directly affects the life of the building, the leakage of some older concrete structures has also attracted widespread attention. Most of the traditional waterproof materials are flexible materials, such as waterproof coiled materials and waterproof coatings. Flexible waterproof materials are spread or sprinkled on the surface of the base of the structure to form a waterproof isolation layer, which is suitable for flat construction and parts with low moisture content of the base....
