Abstract
The utility model discloses the building waste recycled aggregate of waste concrete of a kind of enhancing, belong to building material field.It includes regenerative bone material by concrete, outer surface at concrete regenerating granulated aggregate has the strengthening layer combined closely and penetrate in concrete regenerating granulated aggregate hole and micro-crack, is combine closely integral tack coat and cement shell on strengthening layer the most successively.By the strength ratio untreated concrete crushing strength raising 28 35% of concrete prepared by the building waste recycled aggregate of waste concrete strengthened with such scheme.Can be widely applied in the concrete workses such as municipal administration, building, water conservancy.Can turn waste into wealth, and a large amount of natural aggregate can be saved, bring significant society, economy and environmental benefit.
Description
Technical field
This utility model relates to building material field, the building waste discarded concrete regeneration of a kind of enhancing
Aggregate.
Background technology
Current China annual building waste discharge capacity reaches several hundred million ton, only discarded concrete one and is just up to about 100,000,000
Ton, conventional substantial amounts of building waste is substantially without any process, and simple landfill or outdoor store up, these build rubbish
Rubbish will pollute, and endangers ecological environment.China's significant period of time in future basic architecture engineering is the most very
Huge, the hugest to the quantity consumed of concrete and aggregate thereof, China produces concrete every year to be needed to exploit stone
Son has reached more than 2,000,000,000 tons, excavates rivers sand more than 1,000,000,000 tons.Owing to the most required aggregate is all to nature
Ask for, not only accelerate the exhaustion of natural resources, and heavy damage ecological environment.Construction refuse regenerated aggregate provides
It is the major action of environment of economizing on resources, protect that the research and development in source utilize, and is building materials field growth side
Formula changes, adjusts the important content of product mix and industry structure.Recycled concrete can fundamentally solve brick,
Watt and the problem of outlet of the building waste such as discarded concrete, it is also possible to save natural aggregate resources, alleviate aggregate and supply
Seek contradiction, meet the requirement of sustainable development, be one of main path developing green concrete.
It is reused for after the regeneration approach of building waste discarded concrete is the most broken at present preparing coagulation
Soil.Owing to building waste discarded concrete is through break process, regeneration aggregate self is made to there is many defect cracks,
Therefore common intensity is relatively low, water absorption rate is higher；So simply discarded concrete being added using effect as aggregate
The most highly desirable.Chinese patent 201648248 open a kind of " available building castoff ", it is discarded mixed
Solidifying soil particle surface sprinkling has layer of polyethylene alcoholic solution to form tack coat, wraps in polyvinyl alcohol tie layer surface again
Wrap up in one layer of cement and form cement shell, though recycled aggregate of waste concrete intensity can be made to obtain a certain degree of carrying
Height, but reinforced effects is limited.
Summary of the invention
For solving the technical problem of building waste recycled aggregate of waste concrete recycling, this utility model provides one
Plant intensity higher, the building waste recycled aggregate of waste concrete of the enhancing that water absorption rate is little, alternative natural sandstone
As aggregate.
For achieving the above object, the technical solution adopted in the utility model is: the building waste of a kind of enhancing is discarded
Regenerative bone material by concrete, including concrete regenerating granule, the outer surface at concrete regenerating granule is combined closely
And penetrate into the strengthening layer in concrete regenerating pellet pores and micro-crack, strengthening layer is the most successively
Combine closely integral tack coat and cement shell.
Preferably, described strengthening layer uses waterglass strengthening layer.
Preferably, described tack coat is polyvinyl alcohol tack coat.
The beneficial effects of the utility model are, by with the building waste discarded concrete of such scheme intensive treatment
The untreated concrete crushing strength of strength ratio of concrete prepared by regeneration aggregate improves 28-35%.Can be extensive
It is applied in the concrete workses such as municipal administration, building, water conservancy.Can turn waste into wealth, and a large amount of natural aggregate can be saved,
Significant society, economy and environmental benefit can be brought.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings with embodiment to structure of the present utility model, implementation and effect furtherly
Bright.
Fig. 1 is section structure schematic diagram of the present utility model.
In figure: 1, concrete regenerating granule, 2, waterglass strengthening layer, 3, tack coat, 4, cement shell.
Detailed description of the invention
As it is shown in figure 1, the building waste recycled aggregate of waste concrete of a kind of enhancing is four-layer structure, including mixing
Solidifying soil regeneration granulated aggregate 1, the outer surface at concrete regenerating granule 1 is combined closely and penetrates into concrete
Strengthening layer 2 in regeneration pellet pores and micro-crack, is to be closely integrated into one on strengthening layer the most successively
The tack coat 3 of body and cement shell 4.
Through experiment preferably, described strengthening layer uses waterglass strengthening layer to the present embodiment.Described tack coat is
Polyvinyl alcohol tack coat.
Concrete manufacture method is as follows: is put in water glass solution by building waste discarded concrete regeneration granule and soaks
After dry, form fine and close waterglass strengthening layer 2；Then one layer is sprayed again on fine and close waterglass strengthening layer surface
Poly-vinyl alcohol solution, until waterglass strengthening layer 2 surface suctions liquid and forms tack coat 3, afterwards will be through upper
The building waste discarded concrete regeneration granule stating process puts in blender, then adds cement in blender,
Make tack coat 3 be stained with cement, form one layer of cement shell 4,
Mechanism is: soaks by being put in water glass solution by building waste discarded concrete regeneration granule, dries,
Water glass solution penetrates in building waste discarded concrete regeneration pellet pores and micro-crack and carries out effective filling,
And form vitreous fine and close waterglass strengthening layer at building waste discarded concrete regeneration particle surface, improve
The intensity of building waste discarded concrete regeneration granule self；Poly-second is sprayed again on fine and close waterglass strengthening layer
After enolate solution, add the adhesion to cement, make cement be easy to be coated on building waste discarded concrete
Regeneration particle surface, forms a cement shell, enhances building waste recycled aggregate of waste concrete self
Intensity, also enhances building waste discarded concrete regeneration granule and the caking property of cement, finally improves coagulation
The intensity of soil.
After testing, mixed by prepare with the building waste recycled aggregate of waste concrete of such scheme intensive treatment
The untreated concrete crushing strength of strength ratio of solidifying soil averagely improves 28-35%.
