Embodiment Construction

[0007] A production method of fly ash bricks, comprising the steps of material selection, crushing, batching, mixing, injection of cross-linking agent, compression molding, health care treatment and the like. in:

[0008] Fly ash is selected as the base material; slag, gypsum, and lime are used as fillers; the mixture of concrete admixture and water is used as a crosslinking agent, and the weight ratio of each material in the unit weight is 55-70% for the base material and 28% for the filler. -43%, the crosslinker is 1-3%. The weight ratio of slag, gypsum and lime in the filler is: 2-3:0.1-0.4:1.0-2.0. The weight preparation ratio of concrete admixture and water in the crosslinking agent is: 0.5-1.5: 1-2. Fly ash, slag, gypsum, and lime are crushed into particles with a diameter of 100-800 microns. Mix well according to the amount prepared by the above parameters, inject the glue until uniform, send it to the mold for compression molding, and cure it in a kiln at 50°C-90°C ...

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...
