Method for producing flyash brick

Abstract

A powdered coal ash brick with high compression strength and no shrinking and cracking is proportionally made up of powdered coal ash, slags, gypsum, lime, and the mixture of concrete additive and water through pulverizing, proportional mixing, adding said mixture as cross-linking agent, die pressing and curing.

Description

technical field [0001] The invention relates to a production method of bricks, in particular to a production method of making fly ash bricks with fly ash as the base material. Background technique [0002] At present, fly ash is used as the base material to produce building load-bearing blocks, and the method of building next door blocks is to use cement, ground ash, fly ash, lime, admixtures, and foaming agents as materials, and the input ratio is 2.5:1: 2∶0.2∶0.01∶0.038, the above materials are mixed according to the proportion, and then stirred. ) fast water absorption, low compressive strength, poor plastering effect, easy to produce shrinkage cracks, difficult to mechanical production, high production cost. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a fly ash brick with slow water absorption speed, high compressive strength, strong bonding force with mortar, no shrinkage, no cracks, light weight, sui...
