Problems solved by technology

At present, most of the foamed concrete self-insulating blocks are exterior wall blocks. Due to the low dry density and high compressive strength required by the industry standard for interior wall blocks, hydrogen peroxide is used as a foaming agent, which will affect the strength of the blocks. , so that the block performance index still cannot meet the standard requirements

Abstract

The invention discloses an interior wall self heat-insulation building block. According to specific steps, attapulgite is soaked in water for use; an SCQ animal protein cement concrete foaming agent and water are mixed and made into foam through a foam machine; silicate 425 cement, ultrafine fly ash, II-grade fly ash, I-grade fly ash, quick hardening cement, calcium stearate, an expanding agent, sodium chloride, triethanolamine, polypropylene fibers, basalt fibers and the soaked attapulgite are added into water, mixed and stirred for 2 minutes, then the prepared foam is added and stirred for 10s, then hydrogen peroxide with the mass concentration of 5% is added, after 10s, and the formed paste is poured into a mold and is foamed and shaped in the mold to form a building block; and the surface of the building block is covered with plastic cloth, and after curing and drying, the foamed concrete self heat-insulation interior wall building block is obtained. The building block has the advantages that the process is simple, material blending is scientific and reasonable, the foaming agent has a good foaming effect, pores are uniform, and the product has excellent compressive strength and is suitable for a thermal-insulating interior wall.

Description

technical field [0001] The invention relates to an inner wall self-insulating block, in particular to a foam concrete self-insulating inner wall block. Background technique [0002] Foam concrete self-insulating blocks have the characteristics of green energy saving, environmental protection, heat insulation, fire prevention, and light weight. It can better solve the safety and durability problems of the structural insulation system, maintain the same service life as the building, and greatly shorten the construction period. , also saves the project cost. Foam concrete self-insulating block refers to adding foaming agent to the slurry made of cement-based cementitious materials, admixtures, admixtures and water by physical foaming method, after mixing and pouring , from maintenance. At present, most of the foamed concrete self-insulating blocks are exterior wall blocks. Due to the low dry density and high compressive strength required by the industry standard for interior ...
