Embodiment 1

[0024] refer to figure 1 ,Such as figure 1 The shown aerated concrete block brick of the present invention is made of sea oyster shell powder 15%-25%, fly ash 35%-40%, construction waste 25%-35%, block lime 18% --25%, cement 5%--15%, aluminum powder 1%--5%.

[0025] figure 2 Show a kind of air-entrained concrete block brick production technology of the present invention, comprise the following steps:

[0026] S1, sea oyster shells are pulverized by a pulverizer, then go to the storage powder bin, then go to the ball mill for grinding, then go to the bucket elevator, then go to the storage bin, and then go to the screw mixer, and then weighed by the weighing scale. Then to pouring mixer;

[0027] S2, the fly ash is pulverized by a ball mill, then sent to the slurry tank, then transported to the slurry storage tank by the slurry pump, weighed by the measuring scale, and then sent to the pouring mixer;

[0028] S3, after the construction waste is crushed by the jaw crusher,...

Abstract

The invention discloses an aerated concrete block brick, which is made from 15-25% of oyster shell powder, 35-40% of coal ash, 25-35% of construction waste, 18-25% of lump lime, 5-15% of cement and 1-5% of aluminium powder. According to production technology, oyster shells or mussel shells are pulverized and ground, and the obtained oyster shell powder is taken as a principal material aggregate for producing aerated concrete block bricks according to a reasonable ratio. Due to features of the oyster shell powder, physical properties including lightweight, heat insulation, pressure resistance, fire resistance, sound absorption, endurance, water permeability resistance and workability can be improved by no less than 20%. No pollution is caused during a processing grinding process, and cementing materials, such as cement and gypsum, are saved. Oyster shell incineration for ash production causes pollution due to coal burning, and what's more, oyster shells or mussel shells cannot be degraded, so that pollution generated in the coastal region troubles the government a lot and greatly affects livable city construction. If the production technology is implemented, people's livelihood and environment are improved, and the production technology conforms to the cyclic utilization policy greatly advocated by the government. Therefore, the purpose of wastes to valuables conversion and energy conservation and emission reduction are really achieved.

Description

technical field [0001] The invention relates to an aerated concrete block brick, in particular to an aerated concrete block brick and a production process. Background technique [0002] Most of the existing aerated concrete block bricks use fly ash as the main raw material. During the production process, in order to improve the production performance of the brick floor and the physical and mechanical properties of the product, more mixed cementing materials (such as cement, gypsum, etc.) Because there is no thermal power plant in some areas, the supply of raw material fly ash is far away and the transportation cost is high (energy is wasted in the transportation process), and sand is often used as a substitute for raw materials. Affected, some products are missing edges and corners, and the fracture phenomenon is serious, which affects the qualified rate of finished brick floors, and also generates secondary garbage. [0003] Sea oyster shells are a by-product of aquacultur...
