Description
Technical field
The present invention relates to materials processing technology field, specifically a kind of method for preparing material using aggregate.
Background technique
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
Lead to the increasing of building castoff.Building castoff refers to generated waste when construction, repairerment and demolition of buildings,
Usually there are useless tile block, barren rock material, concrete block, sand-lime soil.Major part waste concrete is all unprocessed direct stacking at present
Or landfill, a large amount of soils, pollution environment are not only occupied, but also cause a large amount of wastes of resource.In recent years due to China
It is built on a large scale always, consumes the construction materials such as a large amount of sand, stone and cement.The natural moneys such as a large amount of exploitation sand, stone
Source causes resource nervous, environmental degradation.People inquire into waste concrete recycle, be mainly prepared as recycled aggregate or
Building element.Since the physical property of waste concrete and natural building material has larger difference, if waste concrete water absorption rate is larger,
Usually 3.6~8%, and the water absorption rate of natural aggregate such as will not ensure that construction quality and made less than 3% using usual method
Use the service life.Energy consumption is high, product cost is higher, product mechanical property is relatively low, use process for also generally existing recycled aggregate processing
The technical problems such as durability difference.
Summary of the invention
It is an object of that present invention to provide a kind of method for preparing material using aggregate, to achieve the above object: the present invention
It provides the following technical solutions:
A method of material is prepared using aggregate, comprising the following steps: after pretreatment by aggregate and ingredient, and additional
Agent mixing, using subsequent processing, the aggregate is the recycled aggregate manufactured with building castoff, and the aggregate is divided into
Middle aggregate and fine aggregate, the ingredient are cement；The material is materials for wall；
The additive be concrete dense curing agent and diamond resin, the subsequent processing be middle aggregate, fine aggregate,
It being filled the water after additive and cement mixing, starts to stir, after stirring 3-5 minutes, be transported to pressing section, curing system is sent into molding,
Maintenance is taken out after 8 hours, is transported in drop trigger, that is, is entered palletizing system；It is cement: thin bone in material addition meter ratio
Material: middle aggregate: additive: water=14-17:28-30:53-55:0.03-0.04:0.01-0.02；
The pretreatment of the aggregate is to make its surface active using water or dust-extraction unit, when preparing colored brick, in ingredient
Pigment can be added, additive amount is calculated as 30-50% by brick quality；
The pressing section of the materials for wall is that the material after stirring is transported to block machine, is to build by extrusion forming
Block or adobe body, then send Plate-stacking apparatus to serve chain scraper conveyor by molding machine, by sweeper by building block or brick billet surface
Dross clean up, be delivered to Lift-slab machine, that is, enter curing system；
The curing system is that building block or adobe body enter Lift-slab machine and expire one layer of rise after three plates, nine layers full up to rising,
When lowermost layer enters Lift-slab machine, multilayer fork truck transfer car(buggy) starts to drive into Lift-slab machine, after the last layer rises in place, multilayer fork
Vehicle transfer car(buggy) once all takes out building block or adobe body from Lift-slab machine, drives into curing kilns, places in curing kilns, using too
Positive energy curing system, automatically adjusts humidity by spray system；Maintenance is taken out after 8 hours, is transported in drop trigger, that is, is entered code
Pile system；
The palletizing system be will after the building block of maintenance or adobe body are sent into drop trigger, drop trigger successively by building block or
Adobe body drops on conveyer, is sent by conveyer to block-pushing machine, building block or adobe body are pushed away bottom plate, building block or adobe by block-pushing machine
Body, which is pulled to, to be turned on block row's brick machine, is turned into level by turning over block assembly, is sent by roller-way to Ma stack machine, building block or adobe body are logical
Ma stack machine code is crossed into six layers, 18 pieces every layer, totally 108 piece of one pile, is most sent pile roller-way to send out workshop afterwards, is sent by fork truck to maintenance heap
, height 2.6m is piled up in maintenance stockyard, can be dispatched from the factory after 7 days.
The beneficial effects of the present invention are:
This method can get a lot of applications regenerated aggregate, while the material applications that production obtains are big, Ke Yizuo
Industry for construction material, materials for wall, many places such as composite material is applied.Improve the market value of product.Prepare work
Skill is simply, conveniently.One aspect of the present invention solves a large amount of building castoff processing difficulties, and ecological environment day as caused by it
The problems such as benefit deteriorates；On the other hand, recycled aggregate substitution natural aggregate is manufactured with building castoff, it is possible to reduce construction industry is to day
The consumption of right resource reduces natural aggregate increasingly scarcity and a large amount of sandstones and is opened to reduce the exploitation to natural sand stone
The extent of the destruction caused by ecological environment is adopted, the living environment of the mankind is protected, ensure that the sustainable development of human society, is accorded with
Close the requirement of sustainable development.
