Hollow fly ash brick and manufacturing method thereof

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...

AI Technical Summary

Problems solved by technology

But its disadvantage is that the brick body is not only a solid structure, but also has a large weight, and it is difficult to align the grooves and convex parts in the actual wall-building process. Moreover, the formula of the fly ash brick is unreasonable, so its formula and structure are both needs to be improved
