Description
Technical field
The present invention relates to a kind of fly ash autoclaved brick and preparation method thereof.
Background technology
Along with country's attention to energy-conserving and environment-protective, the application of flyash brick is more and more extensive.For using coal as fuel
Power plant or other industrial undertakings have processed a large amount of waste residue, decrease processing cost, produce for building materials industry the most again and open
New resource, turns waste into wealth, and has developed recycling economy.Save farmland, support agricultural.Build the fine coal producing 50000000 pieces per year
Ash brick field, can save 50 mu of farmland every year, produce more food about 40,000 jin, has effectively supported agricultural and industrial construction.But at present
Flyash brick weight relatively big, and production cost is higher, and proportioning unreasonable, and granule unreasonable allocation affects product matter
Amount.The consumption to greatest extent of stone powder and flyash can be replaced so that it is reducing into by other industrial waste a kind of
On the basis of Ben can not only rational proportioning, and do not reducing fly ash autoclaved brick intensity even by configuring rational granule
Alleviating the weight of flyash brick on the premise of being an up its intensity is current industry problem in the urgent need to address.
Summary of the invention
It is an object of the invention on the basis of existing, it is provided that the preparation method of a kind of new fly ash autoclaved brick, thus
Reduce the production cost of fly ash autoclaved brick, and play and economize on resources, reduce the pollution to environment, reduce fly ash autoclaved brick
Weight, alleviates the deadweight of building, can optimize building construction design, improve the economy built, promote fly ash autoclaved brick
The purpose of intensity.
The technical scheme is that and be achieved in that: a kind of fly ash autoclaved brick, described fly ash autoclaved brick composition
Including air-entrained concrete building block waste material, stone powder, carbide slurry, flyash, the most each component mass parts in fly ash autoclaved brick
Number is as follows: the air-entrained concrete building block waste material of 35-45 mass fraction, the stone powder of 20-30 mass fraction, 10-20 mass fraction
Carbide slurry, the flyash of 15-25 mass fraction.
Technical scheme can be achieved in that a kind of fly ash autoclaved brick, described fly ash autoclaved brick
Composition includes air-entrained concrete building block waste material, stone powder, carbide slurry, flyash, the most each component matter in fly ash autoclaved brick
Amount number is as follows: the air-entrained concrete building block waste material of 40 mass fractions, the stone powder of 25 mass fractions, the carbide of 15 mass fractions
Mud, the flyash of 20 mass fractions.
Further, described air-entrained concrete building block waste material be mainly composed of flyash, white lime, cement and aluminium powder.
A kind of fly ash autoclaved brick, its preparation method is:
(1) first mix after air-entrained concrete building block waste material, stone powder, carbide slurry, flyash metering proportion, stir
It is stand-by that trailing wheel is ground into compound；
(2) by above-mentioned compound entrance Full Automatic Liquid brick machine be pressed into adobe, put into park between resting stand-by；
(3) by above-mentioned adobe feeding vapor (steam) temperature more than 174.5 DEG C, operating pressure carries out height at the still kettle of more than 0.8MPa
Pressure steam curing, steam curing 10-12 hour is stand-by；
(4) after going out still, steam-pressing brisk is neatly deposited in stockyard and parks, park 1～2 week shrink stable after, detect intensity after parking 1 day
Qualified it is finished product.
Further, pulverized particles a diameter of 0.5-1.5 centimetre of described air-entrained concrete building block waste material.
Owing to stone powder and flyash are consumed relatively big by conventional technique, relatively costly.And utilize periphery air entrained concrete to build
Block factory produces substantial amounts of aerated blocks waste material in process of production and replaces stone powder and the use of flyash, has both solved these Industry Wastes
Material occupies a large amount of soil, the problem that environment causes serious pollution, the proportioning number that more can be found out by the application
According to being effectively improved fly ash autoclaved brick intensity.
In specific implementation process, the granule that air-entrained concrete building block waste material is pulverized is the biggest, the fly ash autoclaved brick made
Weight is the least, and the granule that air-entrained concrete building block waste material is pulverized is the least, and the fly ash autoclaved brick weight made is the biggest；Aerating mixes
Solidifying earth building blocks waste material uses the most, and steam-pressing brisk cost is the lowest, and air-entrained concrete building block waste material uses the fewest, and steam-pressing brisk cost is more
Height, but intensity increases accordingly.When air-entrained concrete building block waste granules diameter is less than 0.5 centimeter, the steam-pressing brisk weight of the present invention
Measure unchanged with existing steam-pressing brisk weight；When air-entrained concrete building block waste granules is between 0.5-1.5 centimetre, 240mm
The weight of standard brick can drop to about 2.2 kilograms from existing about 2.6 kilograms, and the weight of 200mm standard brick can be from existing
About 1.8 kilograms drop to about 1.25 kilograms, ensure brick every qualified in the case of, monolithic brick average weight reduce
0.5 kilogram, this is a quantum jump of building material industry；When air-entrained concrete building block waste granules is more than 1.5 centimeters, although steam pressure
Brick weight is greatly reduced, but now cannot ensure steam-pressing brisk quality.And air-entrained concrete building block waste material uses and accounts for total amount 40% left side
Best results time right, at least can reach 10MPa according to the steam-pressing brisk comprcssive strength made by above-described embodiment.Work as air entrained concrete
In the case of not affecting comprcssive strength, cost is declined, when air-entrained concrete building block waste material makes when building block waste material uses ratio to increase
When reducing by ratio, steam-pressing brisk comprcssive strength can reach 15MPa or 20MPa.
The present invention has the production cost reducing fly ash autoclaved brick, and plays and economize on resources, and reduces the pollution to environment,
Reduce the quality of fly ash autoclaved brick, alleviate the deadweight of building, building construction design can be optimized, improve the economy built
Property, promote the purpose of the intensity of fly ash autoclaved brick.
