Heat-resisting and thermal-insulation cement infrastructure mortar and production method thereof

Abstract

The invention discloses heat-resisting and thermal-insulation cement infrastructure mortar. The mortar is prepared from the following raw materials in parts by weight: 50 to 70 parts of cementing material, 10 to 20 parts of heat-resisting and thermal-insulation aggregate, 0.5 to 1.5 parts of lignosulphonate water reducer, 1 to 3 parts of corrosion inhibitor, 2 to 4 parts of preservative, 0.3 to 0.5 part of polyacrylate emulsion and 0.3 to 0.5 part of low viscosity cellulose ether. The cementing material is prepared from the following raw materials in parts by weight: 30 to 50 parts of Portlandcement, 5 to 10 parts of aluminoferic cement clinker, 5 to 15 parts of active mineral admixture, 0.2 to 0.4 part of compound activator. The heat-resisting and thermal-insulation aggregate is preparedfrom the following raw materials in parts by weight: 100 to 120 parts of quartz sand, 8 to 10 parts of brucite fiber, 8 to 10 parts of polypropylene fiber and 40 to 60 parts of steel slag micropowder. A product of the heat-resisting and thermal-insulation cement infrastructure mortar disclosed by the invention has the advantages of excellent water resistance, waterproofness, impermeability, thermal-insulation property, chemical resistance, heat resistance, weather resistance, high strength and strong adhesive force.

Description

technical field [0001] The invention relates to the technical field of slurry, in particular to a heat-resistant and heat-preserving cement infrastructure mortar and its production method, which can effectively solve the problems of low tension-compression ratio, large drying shrinkage deformation, impermeability, and water resistance of traditional cement infrastructure mortar. cracking, poor corrosion resistance and other issues. Background technique [0002] Mortar is one of the most widely used building materials in construction engineering, and it is widely used in masonry and plastering of buildings. In my country's current construction projects, more than 60% of buildings still use wall materials such as bricks and blocks, and the construction mortar used in masonry and plastering construction is still mainly cement mortar or mixed mortar. [0003] The main way to save energy in buildings is to use thermal insulation materials. In recent years, with the proposal of ...
