Emery wear-resistant floor

Abstract

The invention discloses an emery wear-resisting floor which is prepared from the following components in percentage by weight: 50-70 percent of emery, 5-15 percent of sands, 0-3 percent of an admixture, 0-5 percent of mineral powder, 20-30 percent of cement, 0-1 percent of inorganic salts, 0-0.20 percent of a water reducing agent, 0-1.5 percent of re-dispersible glue powder and the balance of water. The emery wear-resisting floor has the advantages of high strength and compactness, good adhesion, skid resistance and constructability, excellent durability, low shrinkage and small water absorption and is very low in alkali return possibility.

Description

technical field [0001] The invention relates to the field of floors, in particular to an emery wear-resistant floor. Background technique [0002] Ordinary ground concrete is mainly low-strength concrete with a strength of C20-C30, which cannot be directly used as a parking lot floor. With the development of my country's economy and society, the demand for parking lots is increasing. Therefore, it is necessary to make a wear-resistant layer on ordinary concrete. At present, the commonly used processes for wear-resistant floors include epoxy resin floors and emery wear-resistant floors. Epoxy resin flooring has the advantages of beauty, dustproof, and chemical corrosion resistance, and is widely used; however, the cost of raw materials and construction is high, the hardness is poor, and it is easy to be damaged by vehicles, mechanical equipment, etc. Generally, it needs maintenance after 3-5 years. The cost is high, and the weather resistance is poor, so it is not suitable ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the highly active mineral admixtures in emery wear-resistant floors use silica fume. After using silica fume, the floor not only shrinks greatly, but also absorbs a large amount of water, which is likely to cause problems in the durability of the floor.
