Description
Technical field
The present invention relates to a kind of building waste prefabricated component and its manufacturing methods, in particular with floor tile made of building waste
And building block, belong to green building material manufacturing field.
Background technology
With the quickening of China's modernization construction paces, building waste increasingly increases.Relative to house refuse, China
The recycling of building waste do not cause much attention, the overwhelming majority without any processing be just transported to countryside air storage or
Landfill, and stack and landfill then needs to consume the construction funds such as a large amount of expropriation of land, refuse collection, at the same clear in stacking process
It drops and has aggravated environmental pollution again with airborne dust.The quantity of China's building waste has accounted for the 30%-40% of municipal refuse total amount.With
500-600 tons/ten thousand square metres of standard calculates, arrives the year two thousand twenty, and China is new to produce also by about 30,000,000,000 square metres of newly-increased construction area
Raw building waste will be a shocking number.However, most building wastes are just constructed without any processing
Unit transports countryside or rural area, air storage or landfill to, consumes the pork barrels such as a large amount of land acquisition expense, refuse collection expense,
Meanwhile it clearing and causing serious environmental pollution again with the problems such as being flown upward with dust, sand-lime of dropping in stacking process.
And the building waste overwhelming majority of the such flood tide in China just transports countryside or rural area to, adopts without any processing at present
It is handled with random air storage or the mode directly filled, has not only taken up an area but also polluted environment, form that rubbish encloses village, besieged city shows
As seriously affecting town and country image.With the reinforcement protected farmland with environmental protection, the processing mode of traditional building waste,
Through the major issue as enterprise in charge of construction and environmental protection administration's facing.
Therefore, the purpose of the present invention is to provide a kind of building waste prefabricated component manufactured using building waste, raw materials
Including the high pollution solid rubbish such as a large amount of building waste and flyash, produce a kind of it is cheap, have excellent performance, quality it is steady
The green construction materials such as fixed building-block, floor tile and kerbstone.
Invention content
The object of the present invention is to provide a kind of it is cheap, have excellent performance, the building-block of stable quality, floor tile and road
The green construction materials such as kerb.
The invention is realized in this way：
Building waste is mixed with slag micropowder and water, controls moulding process appropriate and in conjunction with a certain amount of auxiliary material and outside
Agent is added to be made with green building materials such as excellent compression strength, freeze proof and anti-permeability performance floor tile, building block and kerbstones.
Not up to above-mentioned purpose, the present invention provides a kind of building waste prefabricated component, raw material includes consisting of：
Building waste：50-80%
Cement：5-10%

Building waste of the present invention can be removed and build from soil excavation, road excavation, old building
Site construction etc. carries out sorting removal, and will by sorting equipment by being output to sorting equipment to the sundries in building waste
Building waste after sorting is output to concentration equipment and carries out magnetic separation, the building waste after magnetic separation is output to vibrating screen, with vibration
Sieve building waste is sieved after, into be crushed, sand processed, drying process, obtain meeting necessarily required building waste.Example
If the granularity of building waste is less than 10mm, the binding performance of building waste and other raw materials can be improved in this way, makes manufacture
Building waste prefabricated component has the mechanical performance indexs such as higher intensity.
Building waste prefabricated component provided by the invention is removed using soil excavation, road excavation, old building and building work
The building wastes such as ground construction are primary raw material, and using slag micropowder as aggregate, to achieve the purpose that have excellent performance.
The present invention using slag micropowder as admixture, can not only reduce the production cost of building waste prefabricated component and
Economic value is considerable；Slag resource can be utilized to solve environmental issue simultaneously, comply fully with the strategy and policy of China's sustainable development
With require.It is wide since blending slag micropowder can make building waste prefabricated component have good mechanical property and stability
It is general to be used for public infrastructure development, indispensable role is played to economic construction.
The present invention also provides a kind of manufacturing methods of above-mentioned building waste prefabricated component, including following steps：
Batch mixing：Raw material is mixed evenly to obtain mixture；
Molding：Mixture is vibrated molding using prefabricated block forming machine, wherein it is 120-170KN to hit power of shaking,
Vibration frequency is 2880-3600 times per minute：
Maintenance：25 hours of maintenance are carried out according to the standard curing method of concrete, then conserve 10 in a natural environment
It, obtains the building waste prefabricated component of the present invention.
In the manufacturing method of building waste prefabricated component according to the present invention, soil excavation may be used, road excavation, old build
It builds the building wastes such as object is removed and construction site is constructed and sorting removal is carried out to the sundries in building waste by sorting equipment, and
Building waste after sorting is output to concentration equipment and carries out magnetic separation, the building waste after magnetic separation is output to vibrating screen, with shaking
After dynamic sieve sieves building waste, into be crushed, sand processed, drying process, obtain meeting necessarily required building rubbish, so
Afterwards according to formula rate carry out material mixing, molding, maintenance and etc..
The substantive point and significant progress of the present invention be：
