Description
Technical field
The present invention relates to environment-friendly production process technical field, specifically a kind of building castoff recycled aggregate and its construction party
Method.
Background technique
Building waste can be understood as the obsolete material generated during construction of buildings, and remove old building
The waste of generation, building waste can be divided into four kinds: foundation pit waste soil is removed waste, building castoff and is fitted up discarded
Object.Foundation pit waste soil, the waste soil exactly generated in excavation of foundation pit, if processing is bad to generate a large amount of dust.It removes
Waste, the inside mainly include cement products, discarded stone material, steel scrap muscle, discarded pipeline, waste plastic etc., these remove useless
Some can be recycled in gurry.Building castoff, mainly some sandstones, concrete, metal, wooden unit and builds
Material etc., these are all the wastes generated in process of construction.Fit up waste, the building materials waste material generated during finishing
With discarded packaging etc., contain more chemical component inside finishing waste, therefore it is required that needing higher processing level.
It stacks and burial is the main processing ways of building castoff, this processing can generate very big harm to environment.
(1) building castoff, the trade waste stacked and buried can generate serious pollution to earth's surface and underground, because
Rainwash, rainwater bring pollutant in building waste into river, polluted surface water；Contaminated surface water permeate the ground and
It polluted underground water.
(2) building castoff, the trade waste stacked and buried can also pollute atmosphere, the building waste arbitrarily stacked,
If having a large amount of dust without processing to generate, powder also can be inevitably generated during transporting building waste
Dirt, this can all produce into dust pollution.In addition, some building wastes due to stacking for a long time, by exposing to the weather, can generate one
In air, this also results in the pollution of atmosphere for a little solid granule floatings.
(3) building castoff, the trade waste stacked and buried occupy a large amount of soil, while stacking and burying
It in the process also can inevitable contaminated soil.Some harmful substances are had in building waste, they enter meeting after soil
A series of physical, chemistry and biological respinse occur in the soil, so that the pollution of soil is caused, the reduction of soil quality.
Building castoff, trade waste prepare ceramic tile bond, the market demand of ceramic tile bond as aggregate
Greatly, a large amount of building castoff can be consumed, while with good economic efficiency.Resource of this research to building castoff
Change the added value and consumption for being conducive to improve building castoff using having important directive function, there is important economy
Meaning and environment protection significance, therefore, it is proposed that a kind of building castoff recycled aggregate and its construction method.
Summary of the invention
The purpose of the present invention is to provide a kind of building castoff recycled aggregate and its construction methods, stack and cover to solve
The problem of burying building castoff pollution environment.
To achieve the above object, the invention provides the following technical scheme:
A kind of building castoff recycled aggregate, including below according to the raw material of parts by weight: 300-400 parts of cement, building are useless
600-700 parts of gurry, 5-15 parts of redispersable latex powder, 0.1-2 parts of starch ether, 1-10 parts of hydroxypropyl methyl cellulose, calcium powder
1-10 parts, 10-30 parts of calcium formate.
As a further solution of the present invention: including below according to the raw material of parts by weight: 345 parts of cement, building castoff
640 parts, 10 parts of redispersable latex powder, 1 part of starch ether, 4 parts of hydroxypropyl methyl cellulose, 5 parts of calcium powder, 20 parts of calcium formate.
As the present invention further scheme: building castoff is the mixture of concrete, brick, ceramic tile, concrete,
Brick, ceramic tile mixture mass ratio be 5:2.4:1.
The construction method of the building castoff recycled aggregate, steps are as follows:
S1, building castoff is carried out to sort out depositary management reason, building castoff will be sieved, after screening, using clear
Water cleans building castoff, first dries building castoff, and the building castoff after drying is then sent into crusher；
S2, crusher is opened, the building castoff after drying is crushed by crusher, the broken grains of sand is obtained, then by broken
Storage sand net slot in broken machine takes the grains of sand out of, and the waste water in crusher is by the mesh outflow of storage sand net slot, and then the grains of sand are from washing
The blanking groove of sand machine is discharged；
S3, by cement, building castoff, redispersable latex powder, starch ether, hydroxypropyl methyl cellulose, calcium powder and first
Sour calcium uniformly mixes, and water is then added, and uniform stirring to paste stands 10min and obtains aggregate mortar, for use；
S4, mortar will be coated uniformly on the ceramic tile of well cutting, mortar coating thickness is 4mm, then will be coated
Sample conserves 28 days；
S5, thermal cycle, Frozen-thawed cycled, immersion processing；
S501, sample is placed in 4h in 80 DEG C of baking ovens, then takes out sample, be cooled to room temperature, then 80 DEG C of processing 4h, are followed
Ring 5 times；
S502, sample is placed in 4h in -18 DEG C of jelly casees, then takes out sample, is warming up to room temperature naturally, then at -18 DEG C
4h is managed, is recycled 5 times；
S503, sample is immersed in pond, Immersion time is 7 days, then dries sample, is placed in 50 DEG C of baking ovens and does
Dry 28h.
As further scheme of the invention: in step S2, crusher is oscillating feeder jaw crusher.
Compared with prior art, the beneficial effects of the present invention are: building castoff recycled aggregate conduct prepared by the present invention
Ceramic tile bond has good product workability, is able to satisfy the requirement of bonding ceramic tile, and extend ceramic tile uses the longevity
Life is conducive to promote the use of.
