Description
Technical field
The present invention relates to building field, be specifically related to a kind of concrete mixed with useless brick and regeneration coarse aggregate and its
Preparation method.
Background technique
With the fast development of construction market, building waste gradually causes our attention.Building waste is to refer mainly to brick
Watt, the engineerings waste such as concrete.China is in high speed extensive capital construction period, in recent years China's housing construction
Area and completed floor space increase year by year, and up to 91.88 hundred million squares of wood, completed floor space is up to the construction area of building construction in 2011
21.98 hundred million square metres, the annual completed floor space of building construction in 2009 to 2011 is more than 2,000,000,000 square metres, furthermore city
The old building removed every year is transformed up to 400,000,000 square metres.It can be seen that building waste specific gravity shared in urban construction by
Year increases.The building waste generated during so large-scale building is removed this how to handle be that emphasis concerned by people is asked
Topic.
China mainly backfills and stacks to the processing mode of building waste at present, and the ratio that its recycling is recycled is not
Foot 1%.A large amount of landfills and the stacking of building waste cause serious influence to environment.First is that occupying damage to land, exacerbate
Shortage of land resource；Second is that pollution environment, pollutes atmosphere, soil and water body, to the ring of nearby residents and entire city
Border is safe and healthy to cause a hidden trouble.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of mixed with the mixed of useless brick and regeneration coarse aggregate
It is negative to alleviate environment so that the resource consumption during greatly reducing architecture construction, realizes the processing of building waste for solidifying soil
Load.
The technical scheme is that mixed with the concrete of useless brick and regeneration coarse aggregate, it is characterized in that: it be by with
Lower raw material is formed by following weight parts: 1-1.6 parts of cementitious material, 1-1.7 parts of fine aggregate and regeneration coarse aggregate 1.2-2.5
Part.
The cementitious material is made of following raw material by following weight parts: 300-600 parts of refuse clay brick powder, high-calcium powder
500-600 parts of coal ash, 5-20 parts of nanoclay, 3-7 parts of borax, 8-30 parts of water-reducing agent, 500-1260 parts of water.
The refuse clay brick powder is to be sieved to be made by broken crusher machine, screening plant by refuse clay brick, and partial size is
0.08~0.4mm, high-calcium fly ass are containing calcium oxide 15% or more；Nanoclay partial size is 30~200nm.
The water-reducing agent is made of following raw material by following weight parts: 25 parts of acetone, 18 parts of calcium lignosulfonate, urine
9 parts of element, 3 parts of formaldehyde, 6 parts of shale ashes, 2 parts of sodium hydrogensulfite, 3 parts of melamine and 4 parts of phenol.
The fine aggregate is partial size in 4.75mm sand below.
The regeneration coarse aggregate is sieved and is made by broken crusher machine, screening plant by barren rock, concrete block,
Partial size 5-31.5mm.
Mixed with the preparation method of useless brick and the concrete of regeneration coarse aggregate, it is characterized in that: the steps include:
1) block of the refuse clay brick and barren rock, concrete of the building rubbish of dismounting is separated；
2) refuse clay brick being sieved by broken crusher machine, screening plant and refuse clay brick powder is made, partial size is 0.08~
0.4mm；
3) barren rock, concrete block are sieved by broken crusher machine, screening plant and regeneration coarse aggregate, partial size is made
0.5-31.5m；
4) take 300-600 parts of the refuse clay brick powder of step 2) with high-calcium fly ass 500-600 parts, 5-20 parts of nanoclay,
3-7 parts of borax, 8-30 parts of water-reducing agent and 500-1260 parts of water are stirred to obtain cementitious material；
5) 1.2-2.5 parts of the regeneration coarse aggregate of step 3) and 1-1.6 parts of step 4) cementitious material and fine aggregate 1-1.7
Part mixing.
The regeneration coarse aggregate is divided into: I regeneration coarse aggregate and II regeneration coarse aggregate；Wherein, I regenerates
Partial size using coarse aggregate is 15-31.5mm；The partial size of II regeneration coarse aggregate is 5-15mm；
The preparation of regeneration coarse aggregate comprises the concrete steps that:
Step 1) is by barren rock, concrete block by broken at the beginning of I crusher, removing soil and light impurities；
Step 2) will just it is broken after barren rock, concrete block through deironing apparatus remove irony ingredient；
Step 3) removes the barren rock of irony ingredient, the partial size of concrete powder is greater than 31.5mm and is sent into II crusher progress wheat-middlings again
It is broken；Enter I screening plant of the partial size less than or equal to 31.5mm sieves, and it is that I regeneration is thick that partial size, which is greater than or equal to 15mm,
Aggregate；Partial size is less than 15mm and sieves into II screening plant, and it is II regeneration coarse aggregate that partial size, which is greater than or equal to 5mm,；Grain
The small 5mm of diameter is namely regenerated to utilize fine aggregate.
The I crusher, II crusher, I screening plant, II screening plant are provided with dust pelletizing system；The I sieve
Subset and II screening plant are screening machine；Deironing apparatus is magnetic separator；The dust pelletizing system is bag filter.
The invention has the advantages that concrete of the invention passes through using useless brick and regeneration coarse aggregate, to subtract significantly
The resource consumption during architecture construction is lacked, has realized the processing of building waste, alleviate environmental pressure.The present invention is using useless
The cementitious material of clay brick powder has sufficiently accomplished environmental protection, energy conservation；High-calcium fly ass self-hardening property is utilized simultaneously, and is received by addition
Rice clay and borax improve hardenite intensity, density and workability.Water-reducing agent of the present invention is bright to concrete reinforcing effect
Aobvious, little loss of slump, low temperature nodeless mesh phenomenon.The application of regeneration coarse aggregate, so that building waste handles adaptation range
Width, it is more environmentally friendly, while regeneration coarse aggregate is during the preparation process, the regeneration fine aggregate screened out can also pass through place
Reason does filling materials for wall body, carries out sufficient resource reclaim recycling in the case where meeting wall and bearing vertical load.
The present invention is described in further details below by Figure of description and specific embodiment, but not as to this hair
Bright restriction.
Detailed description of the invention
Fig. 1 is the process flow chart of regeneration coarse aggregate of the present invention.
