Description
Technical field
The invention belongs to solid waste technical field of comprehensive utilization, and the permeable paving of building waste system is utilized more particularly to a kind of
The method of package material.
Background technology
With the continuous quickening of urbanization process, the generation of building waste and discharge quantity are also in rapid growth in city.
While enjoying urban civilization, also by worry caused by municipal refuse, wherein building waste just occupies quite people
Big ratio accounts for about the 30%-40% of rubbish total amount, therefore how to handle and utilize more and more building wastes, has become
The important topic that government agencies at all levels and building waste processing unit are faced.
Many wastes in building waste are sorted, reject or crush after, be that can be used as regenerated resources again mostly
Utilize, discarded building concrete and discarded masonry are mainly used to production building aggregate at present, prepare such as building block, wallboard,
The building materials such as brick.Dregs can be used for road construction, pile foundation filler, foundation etc..Waste and old brick and tile are burnedc lay class material, warp
It is broken to there is pozzolanic activity, be used as concrete admixture when being milled into powder body material, replacement flyash, slag
Powder, mountain flour etc..But these product market capacitys are limited, added value of product is low, can be with using building waste production seepy material
Meet the permeable pavement material that China " sponge city " is badly in need of, and preferable product profit can be obtained, is conducive to building waste
The expansion of comprehensive utilization scale improves the utilization rate of building waste.
Invention content
The purpose of the present invention is to provide a kind of methods using building waste permeable pavement material, promote building waste
Comprehensive utilization, reduce permeable pavement material manufacture cost.
The present invention is achieved by the following technical solutions：
The present invention is a kind of method using building waste permeable pavement material, it is characterised in that：The method includes following
Several steps：
Step 1: first, sorted to building waste, using multistage building waste sorting machine, by various materials from it is multiple go out
Material mouth is discharged and collects, and removes plastics, metal and timber etc. in building waste, only retains brick and tile, coagulation great soil group solid waste；
Step 2: solid waste passes through crusher in crushing, then screened, is obtained after screening twice by different size sieve
The bulky grain material and granularity of granularity 1-5mm is less than the little particulate material of 1mm；
Step 3: little particulate material and basifier are according to 100：（5-10）Ratio mixing after through ball mill ball milling 6-12h, lived
Material, basifier include one or both of sodium hydroxide, sodium sulphate, sodium metasilicate, calcium hydroxide；
Step 4: then by bulky grain material, activated material, high-strength cement and water according to 50-70%, 5-20%, 10-20%, 8-12%
Weight ratio is uniformly mixed through mixed machine by force, and the high-strength cement refers to the Portland cement water for being not less than 42.5 with label
Mud；
Step 5: mixed material is sent into mold, suppressed by oscillatory type forcing press, vibration frequency 4000-10000r/
Min, time of vibration 30s-90s, then demoulds, and stands maintenance 2-8 days at 10 DEG C -40 DEG C in storehouse, obtains permeable pavement
Material；
Step 6: measuring the permeability rate and compression strength of permeable pavement material, measured using laboratory varying head test method(s) permeable
Rate when experiment, glass tube is filled with water to after needing height, starts stopwatch, and survey is remembered beginning head difference △ h1, after time t, then surveyed
End of a period head difference △ h2 are remembered, by establishing instantaneous Darcy's law, you can the expression formula of osmotic coefficient k is released, if during experiment
The head difference that any time t acts on two sections is △ h, and after time dt, water level decreasing dh in pipe then flows into examination in the dt times
The water of sample is：DVe=- adh,
A is glass tube basal area in formula；The negative sign of right end indicates that water increases with the reduction of △ h, according to Darcy's law, when dt
The seepage discharge of interior effluent test sample is：dVo = k*i*A*dt = k*（△h/L）* A*dt,
In formula, A accumulates for sample section；L is specimen length.
According to the flow principle of continuity, should have dVe=dVo to get to：
k=（a*L/A*t）㏑（△h1/△h2）
Or indicated with common logarithm, then above formula can be written as：
k = 2.3*（a*L/A*t）lg（△h1/△h2）
Permeability rate k criterion of acceptability ranges are maintained at 1.0 × 10-2cm/s-3.5×10-2The range of cm/s；Pass through compression test again
Machine tests compression strength, compression strength criterion of acceptability ranging from 30-40MPa.
The invention has the advantages that：
1, the present invention by brick and tile in building waste and concrete block all of having the high advantage of solid waste utilization rate；
2, process of producing product of the present invention is environmentally protective, non-secondary pollution；
3, the present invention obtains permeable pavement material solid waste content height, and at low cost, added value is high；
4, permeable pavement strength of materials height, the permeability rate that the present invention produces are high；
5, permeable pavement material product produced by the invention market future is preferable, is conducive to the synthesis for further increasing building waste
Utilization rate.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
