Hollow brick

Abstract

The invention discloses a hollow brick. The hollow brick comprises a hollow brick body, which is formed by burning and moulding sludge. The hollow holes in the hollow brick body are in a blind hole structure, the hollow holes on the two sides of the hollow brick body are asymmetrically distributed, and the depth of each hollow hole is 4 to 6 mm. The hollow brick body is in a cubic shape, the length of the hollow brick body is 90-250 mm, the width is 85-125 mm, and the height is 55-120 mm. The hollow brick body is formed by burning sludge and moreover is provided with asymmetrical blind holes on the two sides of the brick body, so the hollow brick is environment-friendly, the waste material namely sludge generated in the households and factories is fully utilized, and furthermore the hollow brick has the advantages of solid structure, strong water penetration resistant performance, and good soundproof and heat insulation effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a hollow brick. Background technique [0002] As the country's policy of prohibiting the production and use of clay bricks continues to strengthen, clay bricks that seriously damage land resources and pollute the atmosphere will gradually be forced to withdraw from the building material market. At present, there are many kinds of bricks in the building materials market, but at the same time, there are few varieties that can use factory polluted and discarded sludge, incinerated chemical plant waste, industrial waste sludge and coal ash to make bricks. At the same time, the existing hollow bricks also have structural defects. For example, the holes on the main body of the bricks are in a through state, and the two brick surfaces that are connected to each other present a symmetrical structure, which is not only easy to seep water, but also has insufficient heat preservation effec...

At present, there are many kinds of bricks in the building materials market, but at the same time, there are few varieties that can use factory polluted and discarded sludge, incinerated chemical plant waste, industrial waste sludge and coal ash to make bricks.

At the same time, the existing hollow bricks also have structural defects. For example, the holes on the main body of the brick are in a through state, and the two brick surfaces that are connected to each other present a symmetrical structure, which is not only easy to seep water, but also has insufficient heat preservation effect.
