Description
Technical field
The present invention relates to materials processing technology field, a kind of method utilizing aggregate to prepare new material.
Background technology
Along with the quickening of the Development of Urban process of China's modernization construction, large-scale new town construction and reconstruction of the old city town
Cause the increasing of building castoff.Building castoff refers to produced garbage when construction, repairerment and demolition of buildings,
Generally there is useless tile block, barren rock material, concrete block, sand-lime soil.Major part waste concrete is all unprocessed direct stacking at present
Or landfill, not only occupy a large amount of soil, pollute environment, and cause a large amount of wastes of resource.Due to China in the last few years
Build the most on a large scale, consume the construction materials such as substantial amounts of sand, stone and cement.Exploit the natural money such as sand, stone in a large number
Source, causes resource nervous, ecological deterioration.People inquire into waste concrete recycle, be mainly prepared as regeneration aggregate or
Building element.Owing to the physical property of waste concrete Yu natural building material has larger difference, as waste concrete water absorption rate is relatively big,
It is usually 3.6～8%, and the water absorption rate of natural aggregate is less than 3%, as used usual method will not ensure that construction quality and make
Use the life-span.Energy consumption is big, product cost is higher, product mechanical property is on the low side, use process in the regeneration aggregate process the most generally existed
The technical problems such as poor durability.
Summary of the invention
Present invention aim at a kind of method utilizing aggregate to prepare new material provided, for achieving the above object: this
The invention following technical scheme of offer:
A kind of method utilizing aggregate to prepare new material, comprises the following steps: by aggregate and dispensing after pretreatment, with
Additive mixes, then through subsequent treatment, counts aggregate by weight proportion: dispensing: be=48-96: 3-with additive ratio
50∶0.01-2。
Described pretreatment is when dispensing is cement, is weighed by metering by cement, when dispensing is waste plastics film, and will be useless
After plastic sheeting is carried out crushing, metering weighs, and the pretreatment of aggregate is to utilize water or dust arrester to make its surface active, when
When preparing colored brick, can add pigment in dispensing, addition is calculated as 30-50% by brick quality.

Additive be retarder；Described when preparing composite, additive is multiple auxiliary agent, and auxiliary agent A is iron powder, and auxiliary agent B is glass
Glass fiber, auxiliary agent C is resin, and auxiliary agent D is auxiliary small powder.
Described aggregate is divided into big aggregate, coarse aggregate, middle aggregate and fine aggregate.
Described subsequent treatment is when preparing materials for wall, will note after middle aggregate, fine aggregate, additive and cement mixing
Water, starts stirring, after stirring 3-5 minute, is transported to pressing section, and curing system is sent in molding, and maintenance is taken out after 8 hours, transported
To fall trigger, i.e. enter palletizing system；
When preparing pavement material, by coarse aggregate, middle aggregate, fine aggregate, additive and cement by water filling after metering mixing,
Discharging after stirring 3-5 minute；
When preparing composite, fine aggregate and auxiliary agent A are carried out activation processing, by the fine aggregate after activation and auxiliary agent A
Delivering to synthesize storehouse with plastic sheeting, auxiliary agent B, auxiliary agent C and auxiliary agent D, after heating compressive reaction, pulp enters mould cooling molding
The pressing section of described materials for wall is that the material after stirring is transported to block machine, by extruded for building
Block or adobe body, then served chain scraper conveyor by the Plate-stacking apparatus that send of forming machine, through sweeper by building block or adobe surface
Scum silica frost clean up, be delivered to Lift-slab machine, i.e. enter curing system；
Described curing system is rise one layer after building block or full three plates of adobe body entrance Lift-slab machine, until rising full nine layers,
When lowermost layer enters Lift-slab machine, multilamellar fork truck transfer car(buggy) starts to drive in Lift-slab machine, and after last layer of rise puts in place, multilamellar is pitched
Building block or brick are once all taken out from Lift-slab machine by car transfer car(buggy), drive in curing kilns, place in curing kilns, utilize solar energy
Curing system, is automatically adjusted humidity by spray system.Maintenance was taken out after 8 hours, was transported to drop in trigger, i.e. entered piling system
System.
Described palletizing system is that block or fragment of brick are successively dropped to by fall trigger after the building block or brick feeding fall trigger of maintenance
On conveyer, conveyer delivering to block-pushing machine, building block or brick are pushed away base plate, building block or brick and are pulled to turn over block row's brick machine by block-pushing machine
On, it is turned into level by turning over block assembly, roller-way delivers to agate stack machine, building block or brick and become six layers by agate stack machine code, every layer
18 pieces, totally 108 piece of one buttress, after through sending buttress roller-way to send workshop, fork truck deliver to maintenance stockyard, height is piled up in maintenance stockyard
2.6m, can dispatch from the factory after 7 days.
Described preparing materials for wall, adding gauge ratio in material is cement: fine aggregate: middle aggregate: additive: water=
14-17∶28-30∶53-55∶0.03-0.04∶0.01-0.02；
Described preparing pavement material, adding gauge ratio in material is cement: fine aggregate: middle aggregate: coarse aggregate: big aggregate
: additive: water=4-5: 30-32: 18-20: 18-20: 18-20: 0.005-0.01: 8-10.Described when preparing composite, outward
Adding agent is multiple auxiliary agent, and adding gauge ratio in material is plastic sheeting: fine aggregate: auxiliary agent A: auxiliary agent B: auxiliary agent C: auxiliary agent D=
48-52∶45-50∶0.3-0.8∶0.3-0.8∶0.3-0.8∶0.3-0.8。
The invention has the beneficial effects as follows:
The aggregate of regeneration can be got a lot of applications by this method, produces the new material purposes obtained big simultaneously, can
Using as construction material, materials for wall, the industry of the many places such as composite is applied.Improve the market value of product.System
Standby technique is simple, convenient.One aspect of the present invention solves a large amount of building castoff difficult treatment, and the ecological ring caused by it
The problems such as border goes from bad to worse；On the other hand, manufacture regeneration aggregate with building castoff and substitute natural aggregate, it is possible to reduce building industry
To natural resources consumption, thus reduce exploitation to natural sandstone, decrease the deficientest and a large amount of sandstone of natural aggregate
It is produced the destructiveness that ecological environment is caused, protects the living environment of the mankind, it is ensured that the sustainable development of human society
Exhibition, meets the requirement of sustainable development.
