Abstract
The invention discloses an autoclave test powder coal ash garbage brick with building garbage, which comprises the following steps: choosing building garbage, powder coal ash, lime (or carbide slag) and additive as main raw material; bruising building garbage (waste concrete, sand pulp, brick, tile and stone) to continuous grading particle with particle size smaller than 10mm; using as skeletal material of autoclave fly ash bricks; using powder coal ash and lime material as cementing agent; adopting hydrothermal synthesis craft; making usage of building garbage at 15%-55% and optimum range at 20%-35%. The hydrothermal synthesis craft is placing the product in the saturated steam with temperature higher 100 deg.c.
Description
Technical field
The present invention relates to a kind of technology of producing autoclaved fly ash brick, especially utilize building waste to produce the technology of autoclaved fly ash brick.
Background technology
Along with the propelling of urbanization process in all parts of the country, the building waste that the old housing reform in the urban construction is made, building removal, reconstruction, extension project bring has become the problem that various places construction sector and department of municipal administration extremely have a headache.Except needs are paid a large amount of land expropriation cost and trucking costs, also pollute the environment and destroy the places of cultural interest.Building waste is as a kind of novel source of pollution, and its improvement work is subject to people's attention just day by day.In addition, in the time of industrial high development, how the deterioration that has also brought urban environment effectively administers source of pollution such as building waste, carbide slag, flyash, has been very urgent problem.Utilizing Calcareous material, flyash, building waste etc. is main raw material(s); the development and production construction material not only can make trade waste and building waste minimizing and resource utilization, but also have gather materials on the spot, on the spot digestion, refuse become precious, save the soil, the effect of protection environment.Being the needs of materials for wall reform, also is simultaneously the needs of construction industry, national economy, social environment and resource coordination development.
Summary of the invention
The present invention is a kind of technology of utilizing building waste to produce autoclaved fly ash brick.This technology is broken into the continuous grading particle of granularity less than 10mm with building waste (discarded concrete, mortar, brick, watt and building stones), aggregate as autoclaved fly ash brick, and be agglutinate with flyash, Calcareous material etc., adopt hydro-thermal synthesis process to produce the building waste autoclaved fly ash brick.The consumption of building waste is 15% ~ 55%, and optimum range is 20% ~ 35%.Hydro-thermal synthesis process is to place the saturation steam more than 100 ℃ to handle in goods.Main component is as follows:
Aggregate: 15%～55%
Flyash: 35%～55%
Lime: 12%～25%
Admixture: 1%～4%
Water: 15%～25%
Embodiment
Embodiment 1
Gravel-concrete aggregate: 35%
Flyash: 35%

At first building waste is carried out artificial go-no-go, then it is broken into the aggregate of particle diameter less than 8mm.Prepare burden according to above-mentioned proportioning, material carries out the standard square that high-pressure molding (pressure is 25MPa) is made 240mm * 15mm * 53mm after rolling, stirring.Brick is placed in the autoclave, and the steam constant voltage of employing 0.8MPa 6 hours goes out autoclave after the cooling naturally and is finished product.
Embodiment 2
Brickbat, waste mortar aggregate: 30%
Flyash: 36%
Lime: 13%
Admixture: 3%
Water: 18%
At first building waste is carried out artificial go-no-go, then it is broken into the aggregate of particle diameter less than 5mm.Prepare burden according to above-mentioned proportioning, material carries out the standard square that high-pressure molding (pressure is 25MPa) is made 240mm * 15mm * 53mm after rolling, stirring.Brick is placed in the autoclave, and the steam constant voltage of employing 0.8MPa 6 hours goes out autoclave after the cooling naturally and is finished product.
