Abstract

The invention discloses a hollow fly ash brick. The formula of the hollow fly ash brick comprises, 4%-9% of dry powder calcium carbide sludge, 50%-60% of rock flour, 25%-30% of fly ash, 10%-15% of sand and 1%-8% of water. By adoption of the formula, the raw material source is wide, cost is low, waste can be recycled, and environment friendliness is achieved. Meanwhile, the hollow fly ash brick can be repeatedly utilized, in other words, if a brick body of the brick made into a finished product is damaged in the transporting process or under other accidental situations, the brick body can be pulverized while regeneration raw materials for making a new brick can be achieved, and pulverizing of the brick body and making the brick body into the regeneration raw materials for the new brick are the innovative characteristic of the hollow fly ash brick. The brick or the hollow brick made by adopting the formula has the beneficial effects that water is not absorbed, so that damp resistance is achieved, heat insulation, heat isolation and sound isolation effects are good, and strength is high. The hollow fly ash brick is taken out from a still kettle and then can be used. The invention further provides a manufacturing method stable in technology.

Description

technical field

[0001] The invention relates to a building material, in particular to a hollow fly ash brick and a manufacturing method thereof. Background technique

[0002] An existing Chinese utility model patent with the application number CN201020245226.5 and the name "fly ash brick" discloses a structure, which includes a brick body, and the upper surface of the brick body is provided with a plurality of concave holes arranged in parallel with each other. groove. A plurality of protrusions arranged in parallel and spaced apart are arranged at corresponding positions on the lower surface of the brick body, and the shape and size of the protrusions correspond to the grooves. The upper surface of the brick body is provided with a plurality of grooves arranged parallel to each other at intervals, which has anti-slip function, and is light in weight and can reduce costs; the lower surface of the brick body is provided with a plurality of protrusions arranged in parallel at...

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1 to Figure 5 As shown, the formula of the hollow fly ash brick of the present embodiment is composed of the following components: 4-9% of dry powdered calcium carbide sludge, 50-60% of stone powder, 25-30% of fly ash, 10-15% of sand, and 1-30% of water 8%.

[0025] The hollow fly ash brick includes a brick body 1, on which a cavity 11 that can save material and reduce weight is distributed. On the left side of the brick body 1, there are 2 to 9 left Protrusions 12, between the left protrusions 12 is formed a left groove 13 in which the adhesive can be embedded when building a wall, and there are 2 to 9 right protrusions 14 distributed on the right side of the brick body 1 A right groove 15 is formed between the right convex part 14 and can also be embedded with a bonding agent when building a wall. The relative positi...
