Description
Technical field
The present invention relates to solid waste recycling field, particularly relate to produce for after the heat treatment such as waste incineration, gasification
Raw bottom ash and building waste reutilization technology, a kind of water-permeable brick utilizing inorganic low slag and building waste to prepare and
Preparation method.
Background technology
The treatment technology such as waste incineration, gasification starts popularization and application on a large scale in China, but at the heat such as waste incineration, gasification
After reason, the inorganic bottom ash of 20% ~ 30% mass can be produced.Therefore, the generation of the inorganic bottom ash of a large amount of heat treatments, the most also can give day by day
Nervous landfill yard increases burden, in order to realize " zero padding is buried " of rubbish, and rubbish heat treatment inorganic bottom ash comprehensive utilization of resources
Become practical ways.
Nowadays the bottom ash recycling produced after the heat treatment such as waste incineration, gasification has been had deeply by countries in the world
Research, as Dutch, German utilization rate up to 99% or more than；Waste incineration bottom ash resource is classified as new weight by the U.S.
Point development scheme.The disposal of resources of waste incineration bottom ash, also from the beginning of 1985, is mentioned in main agenda by China, and
And in succession put into effect regulation and the related economic policy of part waste incineration bottom ash recycling.But on the whole, rubbish burns
The bottom ash utilization rate produced after the heat treatments such as burning, gasification is low, utilization obstacle is uneven, the scope inequality of utilization is still now or even
The significant problem that will solve from now on and research direction.
Along with industrialization, the acceleration of urbanization process, building industry is also the most fast-developing, the building waste produced together
Increasing, the quantity of Chinese architecture rubbish has accounted for more than the 1/3 of municipal refuse total amount.The quantity of China's building waste accounts for
30%-40% to municipal refuse total amount.Calculate, to building waste the year two thousand twenty, China with the standard of 500-600 ton/ten thousand square metre
Also by newly-increased construction area about 30,000,000,000 square metres, newly generated building waste will be a shocking numeral.But, absolutely
Major part building waste, without any process, is just transported to countryside or rural area, air storage or landfill by unit in charge of construction, consumes a large amount of
Land acquisition take, the pork barrel such as refuse collection expense, meanwhile, clear and fly upward with dust, sand-lime with dropping in stacking process
Serious environmental pollution is caused again etc. problem.
The Main Resources Land use systems utilizing present situation, bottom ash and building waste of comprehensive countries in the world has: (1) oil drips
The replacement aggregate on blue or green road surface；(2) the replacement aggregate of cement or concrete；(3) Landfill；(4) embankment, roadbed etc.
Packing material etc..If it is considered that it utilizes position, it is primarily used as land cement based and asphaltic base engineering (such as road, parking
Etc.) and marine building engineering (such as artificial submerged reef, shore protection etc.).
Along with China's ur-banization speed is accelerated, the level of economic development improves, and most cities occurs groundwater resources in succession
Shortage, tropical island effect etc..Causing the main reason of these phenomenons is the change of city underlying surface characteristic, is primarily referred to as manually repairing
The road built, runway, square etc. instead of original soil and vegetation.The structure that these are waterproof, density is big blocks
Water Cycle in city scope, decreases heat of gasification, exacerbates the tropical island effect in city, therefore, increases structure on ground
Porosity, to alleviate urban heat land effect play certain positive role.At present, countries in the world start to advocate permeable pavement
System, wherein water-permeable brick is as a kind of novel ecological product alleviating urban environment decay pressure, and development prospect receives people
Increasing concern.Water-permeable brick is for solving urban surface hardening, building high-quality natural living environment, safeguards that city is raw
The century environment-friendly building materials new product that state balances and is solemnly born.There is the holding water penetration on ground, moisture retention, anti-skidding, high intensity,
The features such as cold-resistant, weather resistance, noise reduction, sound-absorbing.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of utilize prepared by waste incineration bottom ash and building waste permeable
Brick and the preparation method of this water-permeable brick, utilize, the solid waste such as stone in building waste, queen closer, prepares and can be used for
The water-permeable brick that urban road is mated formation, not only solves the fixed-end forces difficult problem of puzzlement China, and can reduce building with the treatment of wastes with processes of wastes against one another
The landfill of rubbish and waste incineration bottom ash takes up an area, it is achieved that recycling.It is an object of the invention to by the following technical programs
Realize:
A kind of water-permeable brick, the raw material of described water-permeable brick includes: gather materials, cement, silicon ash, water reducer and water, the weight portion of each composition
Number ratio is: gather materials: 1350 ~ 1400, cement: 399 ~ 445, silicon ash: 25 ~ 29, water reducer: 3 ~ 4, water: 105 ~ 135；Described gather materials
By house refuse through burn or gasification after produce inorganic bottom ash and comprise stone, building waste two parts of queen closer form.
Further, described water reducer is powder polycarboxylic acids.
Further, of low quality in 30% shared by inorganic low slag in gathering materials described in.
Further, the ratio of weight and number of each composition is: gather materials 1398.68；Cement 444.54；Silicon ash 28.37；Subtract
Water preparation 3.84；Water 133.50；Described water reducer is powder polycarboxylic acids.
The preparation method of described water-permeable brick, including following preparation process:
A, pretreatment: be crushed to, after the inorganic low slag in described gathering materials and building waste being mixed, the bone that particle diameter is 5mm ~ 9.5mm
Material；
B, mixing infiltration: first rinse and gather materials with part washing and will gather materials moistening, the input blender that gathers materials of moistening stirs 25 ~
35s, more remaining water, cement, silicon ash and water reducer are put into stirring 55 ~ 65s in blender, discharging；
C, molding: by the material metage after stirring, add in grinding tool, and on stamping machine, the pressure with 2.5 ~ 3MPa is compressing,
Form removal after standing 1 day；
D, maintenance: after form removal test specimen put into temperature 20 ± 5 DEG C, humidity more than 90% curing box in maintenance, test specimen interval 10 ~
20mm。
The invention has the beneficial effects as follows:
1, the bottom ash after house refuse heat treatment and building waste is used to gather materials as water-permeable brick the basic composition of (aggregate), not only
Instead of the natural aggregate (stone and sand) of a part, decreasing the exploitation to natural resources even wastes；And can be same
Time dissolve large solid waste, allow city walk out the predicament of " garbage-surrounded city ", make rubbish obtain three changes and process, i.e. minimizing, innoxious,
Resource, this invention also reflects Advanced Idea and the developing direction of garbage disposal；
2, the bottom ash after house refuse heat treatment is prepared as water-permeable brick by the present invention, not only solves domestic garbage resources utilization rate
The problem at the end, also provides a kind of novel water permeable material for realization building environmental protection, it is achieved that turn waste into wealth, turn bane into boon；
