Description
Technical field
The invention belongs to field of road is and in particular to a kind of material containing building waste discarded object and its application.
Background technology
According to《Highway road surface construction technique normalizing》In definition, roadbase is in asphalt surface course or concrete
Layer under, with the main supporting course of high-quality material making, road subbase course is under basic unit, with quality more secondary material making time
Want supporting course.In prior art, for roadbase and underlayment paver include cement stabilized soil, lime stabilized soil and
The stable soil of lime industrial residue.Wherein, lime industrial residue is stablized soil and is referred to a number of lime and flyash and other collection
Material (soil, sand, rubble, gravel) matches, and adds appropriate water, the compound obtaining after mix, compacting and health, when it is anti-
When Compressive Strength reaches regulation requirement, the referred to as stable soil of lime industrial residue.The flyash that the stable soil of lime industrial residue adopts, be
The fine ash that coal-burning power plant collects from flue gas.Because fire coal is the second largest pollution sources of urban atmospheric pollution, dirty to air
Dye " contribution " accounts for 16.7%, is only second to the 22.2% of motor vehicle.For administering haze, cut down coal-fired particularly significant.According to
Clean air plan, is closed down coal-burning power plant to Beijing in 2017 comprehensively, and according to this plan, Beijing will not have powder within 2017
Coal ash resource, all flyash repaired the roads rely on outward transport to go to the capital by whole, and cost of repairing the roads will be significantly increased.
Building waste is in the solid waste that building is implemented to produce in newly-built, renovating and enlarging or demolishing process
Thing.Building waste by constituent can be divided into dregs, concrete block, crushed stone, brick and tile fragment, waste mortar, mud, asphalt blocks,
Waste plastics, old metal etc..Building waste has widely corrosion function to our living environment, for building waste such as fruit
No matter the long-term attitude of row, then for urban environmental hygiene, condition of living, land quality assessment etc. has severe shadow
Ring.After building waste is stacked in substantial amounts of first soil, the quality of soil can be reduced, reduce the production capacity of soil；Building waste
It is stacked in the air, affects air quality, some dust granules can be suspended in the air, harmful health；Building waste exists
In stacking process, long-term accumulation is that the harmful substance of building waste penetrates into underground water basin, pollutes water environment；If building rubbish
If rubbish is stacked in city, to urban environment, aesthetics is all unfavorable；It is hidden that the stacking of building waste there may be some safety
Suffer from, at any time it may happen that some accidents.
Content of the invention
The weak point existing for this area, it is an object of the invention to provide a kind of building waste pulverized powder.This is built
Building refuse pulverized powder replaces the road foundation compound that flyash produces to have low cost, and compression strength is high, and impermeability waits well special
Point.
It is another object of the present invention to proposing the application of described building waste pulverized powder.
The concrete technical scheme realizing the object of the invention is：
A kind of building waste pulverized powder, including one or more levigate in waste concrete, useless brick and tile and useless foamed bricks
Powder.
Further, part by weight shared by useless brick and tile pulverized powder in described building waste pulverized powder is (40-70) %, gives up
Part by weight shared by concrete pulverized powder is (20-30) %, and part by weight shared by useless foamed bricks pulverized powder is (10-30) %.
Wherein said waste concrete, useless brick and tile and useless foamed bricks mix in proportion and jointly levigate pass through 0.075mm to 70%
Sieve aperture, must not contain the debris such as wood chip, plastics, metal in powder.
All containing potential active ingredient in useless brick and tile and useless foamed bricks, by the alkali of lime in the stable soil of lime industrial residue
Property excite, can produce certain cementation increases entire compression intensity.The water of not hydration reaction completely is contained in waste concrete
The alkaline matters such as mud particle, can replace part lime, improve the intensity of stable soil, can excite useless brick and tile and useless foamed bricks simultaneously
Activity increases stable soil bulk strength and density further, improves water-resistance.
Wherein, described building waste pulverized powder be waste concrete, useless brick and tile and useless foamed bricks are mixed in proportion after through Hubei Province
Formula crusher in crushing is to particle diameter (30-50) mm, then is crushed to after 0-5mm through cone crusher or sand making machine, then is ground by grinding machine
Thin obtained by 0.075mm sieve aperture to the 70% of product.Described grinding machine is ball mill, vertical mill, column mill, in DMC grinding machine
A kind of.
Application in road construction for the building waste pulverized powder of the present invention.
Specifically, described application, is to replace flyash with building waste pulverized powder, for laying road basic unit and/or
Underlayment.
Further, described application, is with lime or quick lime, gathering materials mixes by described building waste pulverized powder, is used for
Laying road basic unit and/or underlayment；Described building waste pulverized powder, lime or quick lime, the mass ratio gathering materials are 12-
16：3-4：800-900.
The maximum particle size wherein gathering materials is less than 37.5mm.
The beneficial effects of the present invention is：
The present invention proposes the stable soil building waste pulverized powder of roadbase underlayment lime industrial residue, and it is by giving up
Brick and tile, waste concrete and useless foamed bricks are crushed to particle diameter (30-50) mm through jaw crusher after mixing by a certain percentage, then through cone
After formula disintegrating machine or sand making machine are crushed to 0-5mm, then the active powder being finely ground to by grinding machines such as ball milling, Vertical Mills, can 100% generation
It is used for the production of the stable soil of roadbase underlayment lime industrial residue for flyash, and performance is better than flyash in proportion and stablizes
Soil.
The roadbase underlayment lime industrial residue that this building waste pulverized powder replacement flyash produces is stablized soil and is had
Low cost, compression strength is high, the features such as impervious good.Be particularly well-suited to Beijing so will have the high fire coal that limits to send out to air quality
Electricity or the city popularization and application of fly ash shortage.The invention of this building waste pulverized powder for improve roads engineering quality,
Reduce construction costs, reduce environmental pollution, promote the smooth enforcement of China's strategy of sustainable development to have important economy with now
Sincere justice.
Compared with stablizing soil with tradition, the stable soil of present invention preparation has following features：Bulk strength and density increase,
It is applied to high-grade highway construction.It is suitable for promoting the use of in the city of reduction coal fired power generation and can highlight cost advantage.
