Description

The preparation method that hollow concrete is laid bricks is prepared using discarded concrete
Technical field
The present invention relates to hollow concrete lay bricks preparation method more particularly to it is a kind of using discarded concrete prepare it is hollow mix The preparation method that solidifying soil is laid bricks.
Background technique
With the development of economy and social progress, more and more concrete structures buildings are because reaching service life or not It is able to satisfy application demand and is removed, thereby produce a large amount of discarded concrete.According to statistics, China is produced because removing building every year Raw solid waste is at 200,000,000 tons or more, and wherein the overwhelming majority is discarded concrete；However having for these discarded concretes Effect processing method is few, and traditional processing method mainly transports countryside air storage or landfill to, and this method can bring height High processing cost simultaneously causes a series of environmental problems.On the one hand, the annual output of chinese concrete accounts for the 45% of world's total amount, gives up It is increasingly severe to abandon concrete bring problem of environmental pollution；On the other hand, production concrete needs a large amount of mineral aggregate, mine money Source needs to be protected as a kind of non-renewable resources.
Aggregate of traditional mineral aggregate as fresh concrete is replaced after discarded concrete is broken, both can be well solved discarded mixed Problem of environmental pollution caused by solidifying soil, and mine resources have been saved, and engineering cost can be reduced to a certain extent.And broken Aggregate cannot be come directly as construction material using each side's surface properties of discarded concrete aggregate are different from natural aggregate；I.e. Make to mix discarded concrete aggregate with cement mortar as concrete use, requires concrete strength is higher to answer some With in field, such as armored concrete, it is that cannot reach wanting for armored concrete with discarded concrete aggregate replacement natural aggregate It asks, this just can not effectively digest Chinese so huge discarded concrete, and the utilization of discarded concrete also just can not be a wide range of Ground is applied in building field, and how to efficiently use discarded concrete and broken discarded concrete aggregate is construction material The big technical problem of one faced in field, and studying the technical task of tackling key problem, contain in huge economic benefit.
Summary of the invention
Place in view of the shortcomings of the prior art is prepared the purpose of the present invention is to provide a kind of using discarded concrete Discarded concrete is crushed, screens and hybrid reaction produces regenerative gel in proportion by the preparation method that hollow concrete is laid bricks Material prepares hollow concrete and lays bricks, can be widely applied then in conjunction with regenerative gel material and other proportion components It utilizes, has a vast market foreground, and saved a large amount of mine resources, improve the economic value of discarded concrete.

Rod-toothed crusher B (4) is that 10~40mm discarded concrete particle carries out splitting break process, partial size 25mm or less to partial size Discarded concrete particle entered in screening machine B (6) by the material outlet B of rod-toothed crusher B (4), partial size is greater than 25mm Discarded concrete particle will continuation carry out splitting break process in rod-toothed crusher B (4)；Screening machine B (6) is by partial size 25mm Discarded concrete particle screening below is that 5~25mm discarded concrete particle and partial size are less than 5mm discarded concrete at partial size Particle, the discarded concrete particle that wherein partial size is 5~25mm are delivered to regenerated coarse aggregate storage bin by screening machine B (6) (7), the discarded concrete particle that partial size is 5~25mm is regenerated coarse aggregate；Partial size is less than 5mm discarded concrete particle and passes through sieve Extension set B (6) is delivered to recycled fine aggregate storage bin (8)；
Discarded concrete particle of the rod-toothed crusher C (5) to partial size less than 10mm carries out splitting break process, partial size 5mm or less Discarded concrete particle entered in recycled fine aggregate storage bin (8) by the material outlet C of rod-toothed crusher C (5)；Partial size Continuation is carried out splitting break process in rod-toothed crusher C (5) by the discarded concrete particle greater than 5mm；
Recycled fine aggregate storage bin (8) stores partial size 5mm discarded concrete particle below, and vibrating screening machine (81) will regenerate thin Partial size 0.5mm discarded concrete particulate emission below is transported in fine powder storage bin in aggregate storing case (8), partial size 0.5mm Discarded concrete particle below falls into the water of fine powder storage bin and would not fly again；Recycled fine aggregate storage bin (8) at this time It stores partial size to be greater than 0.5mm and be less than or equal to the discarded concrete particle of 5mm, which is recycled fine aggregate；
B, prepared by regenerative gel material: the regenerated coarse aggregate of regenerated coarse aggregate storage bin (7) in step A and recycled fine aggregate are stored up The recycled fine aggregate for depositing case (8) carries out proportion according to following mass fraction and regenerative gel mixed material is made:
Regenerated coarse aggregate: 275 parts；
Recycled fine aggregate: 140 parts；
Then by regenerative gel mixed material in 695 DEG C of temperature lower calcinations, 5 hours obtained regenerative gel materials；
C, it concrete building brick material mixture ratio: matches according to following mass fraction into concrete building brick material:
Regenerative gel material: 635 parts；
Polypropylene fibre: 4 parts；Its fibre length is 1.5~200.0mm；
Cement: 340 parts；
Silicon powder: 60 parts；Wherein the average grain diameter of silicon powder is 0.3~0.8 μm；
Haydite: 47 parts；Wherein haydite is the particle of 1.5~3.0mm of partial size；
Bonding agent: 54 parts；Bonding agent is epoxy resin；
Pore former: 6 parts；Pore former is the mixture of linear phenol-aldehyde resin, polyethylene glycol；
The stirring of concrete building brick material is sufficiently mixed, the water that mass fraction is 85 parts is then added into concrete building brick material Stirring 20~30 minutes for the first time；It is subsequently added into second of stirring of water that mass fraction is 115 parts and obtains coagulation in 30~45 minutes Soil is laid bricks slurry；The moisture content for controlling concrete building brick slurry is lower than 30wt%；
D, hollow concrete is laid bricks preparation: the concrete building brick slurry of step C being poured into hollow concrete and is laid bricks in molding die Molding, demoulding is made hollow concrete and lays bricks after being then allowed to stand 16 hours, lays bricks to the hollow concrete after demoulding and carries out dioxy Change carbon to conserve 7 hours, gas concentration lwevel when curing with carbon dioxide is 60%, and control hollow concrete lay bricks it is aqueous Rate is lower than 10wt%, finally obtains hollow concrete and lays bricks finished product.
