Abstract
The invention relates to the technical field of producing building materials by utilizing industrial waste, in particular to a high-strength autoclaved flyash-lime brick and a production method thereof. The weight ratio flyash to carbide slurry to furnace slag is 70:20:10. The production method comprises the following steps of: by metering according to the weight ratio, sending the raw materials to a stirrer for mixing the materials and adding water to compulsively stir the materials; sending the stirred mixed materials to two wheel mills for grinding; sending the ground raw materials to a wall brick press for molding; and sending molded adobes to a still kettle for stilling to obtain finish product bricks. The raw material formula of the high-strength autoclaved flyash-lime brick is simple, and the dosage of the flyash reaches up to 70 percent. Raw materials such as quicklime or gypsum, and the like do not need to be added, thus resources are saved, and the raw material cost is reduced. The dosage of carbide slurry which is a high-pollution material reaches up to 20 percent, thus the problem that the high-pollution material pollutes the environment is solved. The properties of compressive strength, breaking strength, volume density, and the like of the finished product brick all reach the equivalent technical standard of like products.
Description
Technical field:
The invention belongs to and utilize trade waste production building material technical field, particularly a kind of high-strength autoclaved flyash-lime brick and production method thereof.
Background technology:
At present,, all must contain during its raw material constitutes, also must add the quicklime of cementation or gypsum etc. simultaneously as the material of aggregate element such as middle fine sand etc. though utilize fly ash in electric power plant a lot of for the technology of main material production constructional materials.Composition of raw materials is too complicated, has inevitably reduced the addition of flyash, and the cost of raw material is too high.
Summary of the invention:
The present invention is intended to solve the above-mentioned drawback that prior art exists, and provides a kind of composition of raw materials simple, can improve the flyash addition, and especially adopting high pollution discarded object calcium carbide mud is the high-strength autoclaved flyash-lime brick and the production method thereof of raw material.
The technical scheme that the present invention solves this technical problem employing is:
A kind of high-strength autoclaved flyash-lime brick is made up of flyash, calcium carbide mud, slag, and the weight proportion of each component raw material is:
Flyash: calcium carbide mud: slag=70: 20: 10
The production method of this high-strength autoclaved flyash-lime brick is: accurately measure the each component raw material by composition of raw materials, deliver to dual horizontal axle forced mixer batch mixing and add water and force to stir; Compound through forcing stirring to be made is delivered to the first road edge runner by belt conveyor and rolls; Raw material after the first road edge runner rolls is delivered to the second road edge runner by belt conveyor and rolls; Raw material after the second road edge runner rolls is delivered to fully automatic hydraulic wall body brick press-molding by belt conveyor, and briquetting pressure is 240kg/cm
2, molding cycle 12～15 seconds; It is steam-cured that formed green brick is delivered to still kettle, steam-cured pressure≤13kg/cm
2, steam-cured temperature is no more than 200 ℃, and the steam-cured time is 8～9 hours; Brick after still kettle is steam-cured is the finished product high-strength autoclaved flyash-lime brick.
Compared with prior art, technical advantage of the present invention is:
1. composition of raw materials is simple, and three kinds of raw materials are trade waste, and especially the flyash consumption is up to 70%.
2. need not in the raw material to add raw materials such as quicklime or gypsum, when economizing on resources, also reduced cost of material.
3. added the calcium carbide mud up to 20% in the raw material, and calcium carbide mud is the high pollution thing, therefore can solve the high pollution thing influences problem of environment.
4. finished bricks resistance to compression, rupture strength height, bulk density is big.After testing, compressive strength 〉=15.0Mp, rupture strength 〉=3.3Mp, bulk density is 1348kg/m
3, reached like product equivalent technology standard.
The specific embodiment:
Below in conjunction with embodiment in detail the present invention is described in detail.
The described high-strength autoclaved flyash-lime brick of present embodiment is made up of flyash, calcium carbide mud, slag, and the weight proportion of each material component is:
