Abstract
The invention relates to a fly ash sintered brick and a production process thereof. The brick comprises components in percentage by mass as follows: 25% of yellow sand, 15% of calcium carbide slurry, 10% of fly ash, 30% of furnace slag and 20% of stone powder. The production process comprises steps as follows: settling, decomposition, brick making, primary curing, high-temperature curing and pressure maintaining. Common industrial waste or sand resources are taken as raw materials, and the environment-friendly fly ash brick is manufactured in cooperation of a scientific curing technology, has the characteristics of high strength, high compactness, small water absorption, high impermeability, lightweight, high pressure resistance, moisture prevention, sound insulation, thermal insulation and the like, can be used for a load bearing wall, can be used for a filling material of a framework structure due to lightweight, is applicable to wall engineering of industrial and civil construction and meets the strict requirements of people for the living environment.
Description
Technical field
The present invention relates to building brick material field, is a kind of flyash brick material and production technique thereof specifically.
Background technology
In recent years, improving constantly of people's living standard, environmental consciousness constantly strengthens, the industrial production means of much traditional low output high energy consumption and product all gradually by the free of contamination new technique of environmental protection and product innovation replace, and building trade is in recent years developed gradually, vigorous based on the material of construction demand of brick material.
Brick material generally adopts unburned mode to make now, reduce the generation of pollutent, improve brick material amount and production efficiency, along with the requirement of people to living environment is more and more higher, the over-all properties of brick material is also subject to people and pays close attention to greatly, light weight, and mechanical property is good, moistureproof damp proof brick material is standby to be received by the market, and people need a kind of production technique that can improve brick material over-all properties for this reason.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of flyash brick material and production technique thereof.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of flyash brick material, described brick material comprises yellow sand, carbide slurry, electric coal ash, slag and stone flour, and the mass percent of described each composition is: yellow sand 25%, carbide slurry 15%, electric coal ash 10%, slag 30%, stone flour 20%.
A production technique for flyash brick material, comprises the following steps:
(1) precipitation is cleared up: the mixture of described batching is left standstill 30 hours;
(2) brickmaking: the batching after precipitation being cleared up utilizes brick press to make brick material after adding water and stirring;
(3) just maintenance: brick material is put into the pressurize of concrete autoclave, temperature in concrete autoclave is increased to 70 DEG C to 100 DEG C, pressurize 60 minutes;
(4) High Temperature Curing: temperature in concrete autoclave is increased to 180 DEG C, the pressure of maintenance 12MPa 80 minutes;
(5) pressurize: brick material is continued pressurize 6 hours in concrete autoclave, and concrete autoclave internal gas pressure is down to 6MPa to 7MPa, take out brick material afterwards.
The invention has the beneficial effects as follows: the present invention with common industrial waste or sandstone resource for raw material coordinates the maintaining process of science to make environment-friendly type flyash brick, have that intensity is high, degree of compactness is large, water-intake rate is little, impermeability is strong, brick light weight, compressive resistance are high, damp proof, sound insulation, the feature such as heat insulation, can be used for bearing wall, because of its light weight, also can be used for the packing material of skeleton construction, be applicable to industry and the walling work of covil construction, meet the strict demand of people to living environment.
Embodiment
The technique means realized to make the present invention and creation characteristic are easy to understand, and set forth further below to the present invention.
A kind of flyash brick material, described brick material comprises yellow sand, carbide slurry, electric coal ash, slag and stone flour, and the mass percent of described each composition is: yellow sand 25%, carbide slurry 15%, electric coal ash 10%, slag 30%, stone flour 20%.
A production technique for flyash brick material, comprises the following steps:
(1) precipitation is cleared up: added water by the mixture of described batching after stirring and leave standstill 30 hours, precipitation is exactly the process allowing crystal grow up, after precipitation, particle is uneven, precipitation is exactly that each particle is balanced through resolution of precipitate by aqueous phase (sedimentary saturated solution), make precipitate size even, structural integrity;
(2) brickmaking: the batching after precipitation being cleared up utilizes brick press to make brick material;
(3) just maintenance: brick material is put into the pressurize of concrete autoclave, temperature in concrete autoclave is increased to 70 DEG C to 100 DEG C, pressurize 60 minutes;
(4) High Temperature Curing: get off through the Stability Analysis of Structures of first maintenance by brick material, then temperature in concrete autoclave is increased to 180 DEG C, the pressure of maintenance 12MPa 80 minutes, thoroughly by the compacting of brick material, evaporate to dryness;
(5) pressurize: brick material is continued pressurize 6 hours in concrete autoclave, and concrete autoclave internal gas pressure is down to 6MPa to 7MPa, take out brick material afterwards.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and specification sheets; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
