Problems solved by technology

At present, most of the existing thermal insulation exterior wall panels for buildings are made of ordinary portland cement concrete. Portland cement has a high modulus of elasticity and is a typical brittle material. The freezing and thawing performance is extremely poor, which cannot meet the requirements of building insulation engineering
For this reason, technicians add a foaming agent to the Portland cement concrete, and foam the room to make cement foam concrete. The cement foam concrete also has important problems such as long setting time, difficulty in forming and demoulding the test piece, etc.
As a result, the building exterior wall insulation construction period is longer and the production efficiency is low

Abstract

The invention provides foamed concrete and a production process thereof. The foamed concrete is prepared from, by weight, 95-98% of aluminum sulfate cement, 0.05-0.2% of sodium metaaluminate, 0.05-0.2% of aluminum sulfate and 2-5% of hydrogen peroxide. The production process of the foamed concrete includes steps: 1, raw material preparation; 2, stirring and mixing; 3, adding hydrogen peroxide into a stirrer, and continuing mixing and stirring; 4, performing foam forming; 5, demoulding. The aluminum sulfate cement is used as a main material, a foaming agent, an accelerator and a set control agent are added, and then adding into a mould for foam forming is performed after well mixing. The foamed concrete has advantages of great thermal preservation effects, low cost and short set time, and accordingly foam concrete production efficiency can be effectively improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of production and manufacture of foamed concrete and its products, and in particular relates to a foamed concrete and its production process. Background technique [0002] With the continuous improvement of people's living standards, the voice for the improvement of living conditions is also getting higher and higher, thus greatly promoting the rapid development of the construction industry. Building exterior wall insulation and energy saving has also gradually entered the public's field of vision. At present, most of the existing thermal insulation exterior wall panels for buildings are made of ordinary portland cement concrete. Portland cement has a high modulus of elasticity and is a typical brittle material. The freeze-thaw performance is extremely poor and cannot meet the requirements of building insulation engineering. For this reason, technicians add a foaming agent to Portland cement concrete, and ...
