Lightweight foam concrete insulating brick and its manufacturing method

Abstract

The invention relates to a naturally maintained lightweight foam concrete insulating brick which is made of a lightweight insulating material and needs no sintering, autoclaving, and steam curing, and its manufacturing method. The lightweight foam concrete insulating brick comprises by mass: 35%-45% of fly ash, 5%-16% of aggregates, 8%-15% of cement, 2%-8% of slag, 8%-18% of quicklime powder, 4%-10% of plaster stone powder, 2%-5% of expanded perlite, 0.5%-3% of polystyrene foam, 0.5%-5% of an activator, 2%-5% of an early strength agent, and 15%-20% of water. The aggregates can be zeolite, or basalt tailling slag or an arbitrary combination thereof. The brick of the invention has the advantages of energy saving and environmental protection as well as low cost, and its manufacturing technology free of sintering, autoclaving, and steam curing can effectively reduce original ecological resource consumption. By comprehensive utilization of fly ash and polystyrene material wastes, zeolite, basalt tailling slag particles and other materials, the building cost can be effectively reduced.

Description

technical field [0001] The invention relates to a building wall masonry material, in particular to a light-weight foam concrete heat-insulation brick made of a light-weight heat-preservation material without sintering, autoclaving, steam-curing, and natural curing and a manufacturing method thereof. Background technique [0002] At present, there are many places where the building wall masonry materials in the vast areas of our country mainly use clay sintered bricks, coal gangue sintered bricks, non-sintered clay bricks, non-sintered garbage tailings bricks, and autoclaved and steam-cured fly ash bricks. Metallurgical industry waste slag bricks, coal gangue bricks, lightweight foam bricks, autoclaved lime-sand bricks, and small hollow blocks of light aggregate concrete without sintering, autoclaving, and steam curing. In recent years, the reinforced concrete shear wall and steel mesh frame concrete building system have been developed and applied. [0003] Clay sintered bri...

AI Technical Summary

Problems solved by technology

Metallurgical industry waste slag non-sintered bricks, tailings slag non-sintered bricks, and lightweight foamed non-sintered bricks all require autoclaving, and the secondary energy consumption of steam curing is still high. pressure, without steam curing, but still use the original ecological resource ordinary sand, resulting in heavy blocks, correspondingly increasing the amount of materials used for building foundations, beams, slabs, columns and construction costs

The cast-in-place reinforced concrete shear wall and steel mesh frame concrete building system need to be equipped with large-scale concrete pumping equipment, and the construction process is complicated. The wall material itself does not have thermal insulation, and the external wall sticky thermal insulation material needs to be used, and the construction process is correspondingly complicated. , the construction cost is high, and the thermal insulation material is flammable, easy to age and fall off after a long time, there are cold and thermal bridge effects and many unsafe hidden dangers
