Building material with high toughness and good water resistance and having anti-cracking effect and preparation method of building material

Abstract

The invention relates to the technical field of building materials and discloses a building material with high toughness and good water resistance and having an anti-cracking effect. The building material is prepared from the following raw materials in parts by weight: 20-40 parts of composite fiber material, 30-50 parts of Portland cement, 10-15 parts of calcium carbonate, 5-10 parts of fly ash,3-7 parts of silica powder, 1-4 parts of copper stearate, 0.5-2 parts of polycarboxylate, 1-3 parts of methyl cellulose and 1-2 parts of ethylene-vinyl acetate copolymer. The building material with high toughness and good water resistance and having the anti-cracking effect and the preparation method of the building material have the advantages that by adding the composite fiber material, Portlandcement, calcium carbonate, fly ash, silica powder, copper stearate, polycarboxylate and methyl cellulose, the toughness and the anti-cracking effect of the material with high toughness and good waterresistance and having the anti-cracking effect are improved, the composite fiber is uniformly distributed through a dispersing agent, mechanical properties are changed, the deformation resistance ofthe material is obviously improved, and the concrete cracking and fracture probability is reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building material with high toughness, good water resistance and crack resistance and a preparation method thereof. Background technique [0002] Building is a structure that people use all available materials such as earth, stone, wood, steel, glass, reed, plastic and ice to build. The building itself is not the purpose. The purpose of building is to obtain the "space" formed by the building. In order to meet the needs of social life, people use the material and technological means they have mastered, and use certain scientific laws, Feng Shui concepts and aesthetic principles to create artificial environments, building materials, and materials used in buildings are collectively referred to as building materials. New types of buildings Materials include a wide range, including thermal insulation materials, heat insulation materials, high-strength materials and mater...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a building material with high toughness, good water resistance and crack resistance and a preparation method thereof, which has the advantages of good water resistance, etc., and solves the problem that a large amount of water is used when the building is in use. The materials used are generally soil, stone, wood, steel, glass, reed, plastic and ice, etc., and the effect is very general. Ordinary building materials cannot play a role in waterproofing. Prolonged exposure to rain may cause water leakage in the house. , it is very inconvenient to use, and the toughness is not good when used, cracking and breaking may occur, which is very dangerous to use
