Fly ash brick unbaking shaping method

Abstract

A non-calcine method for preparing the flyash brick includes such steps as proportionally mixing flyash slags, calcium carbide dregs, ardealite and cement, and activating by overheat steam, homogenizing, adding atomized water, stirring, moulding, and curing.

Description

technical field [0001] The invention relates to a manufacturing process of fly ash building materials, in particular to a high-volume fly ash brick-free molding method, which is also suitable for processing non-burning fly ash blocks and fly ash silicon-calcium boards, etc. . Background technique [0002] At present, the use of fly ash building materials to replace traditional sintered solid clay bricks is not only because clay bricks consume more energy, seriously occupy land and destroy fields, and have been strictly restricted in production and use, but also because of The amount is increasing day by day, which not only pollutes the environment, but also takes up a lot of land, and becomes a big public hazard. Therefore, in order to eradicate the pollution of fly ash, make full use of the potential activity and other properties of fly ash, and use it as a resource-rich and cheap raw material for comprehensive utilization to produce building materials, it has been widely ...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to provide a kind of non-burning molding method of fly ash brick, which effectively overcomes the defects of large equipment investment, high operating cost and low production efficiency in the prior art, and has the advantages of simplified process flow and short production cycle. Energy saving, reasonable equipment matching design, easy operation, high control precision, less floor space, low investment, low operating cost, remarkable effect of material activation and activation, effectively improving product quality and production efficiency
