The celluar concrete prepared for a kind of road waste aggregate set forth above, concrete preparation technology is such as
Under:
(1) prepared by raw material:
1) preparation of regeneration aggregate: select the discarded concrete after road reformation, after being exposed to the sun 1-2 hour in the sun, make employment
Work or machinery hammering or cutting；After pulverizing the granule for 45-60cm particle diameter, after being again exposed to the sun 1-2 hour, carry out the hammering of secondary
Or cutting；
After pulverizing the granule for 30-40cm particle diameter, using grating is that 10～20 vibrosieves are screened, and at the sieve gradually successively decreased
Sieved 2-3 time in time segment；
After screening terminates, at the water glass solution of the surface smear 15%-20% of regeneration aggregate, and smear uniformly, treat that waterglass is molten
Regeneration aggregate, completely into behind regeneration aggregate inside, is transferred in hothouse be dried and maintenance process, is placing by liquid
Take out after 10-15 days.
2) preparation of slag: by the slag as main component with vessel slag or open hearth slag, use manually or mechanically carries out pre-
After pulverizing, then toast, after it is completely dried stop, subsequently by heat vexed rear efflorescence slag in bulk slag steel with
Slag separates, and first carries out bulk slag steel magnetic separation, and then slag is after multiple stage crushing screening magnetic separation, extracts slag steel；
3) preparation of additive: by high efficiency water reducing agent, bentonite, caoutchouc latex, thin iron powder, organic flocculant on demand
Component and quality carry out proportioning, will enter water simultaneously and mix, and stop after the surface bubble-free of liquid to be mixed；
(2) the preliminary mixing of raw material: under room temperature state, regeneration aggregate after processing, slag, cement are according to the ratio of 4:2:1
Example is put into and is mixed to stirring container, and adds the additive that polypropylene film-fibre, sand and 2/3 mix, and adds subsequently
Enter the water with above-mentioned raw materials quality proportioning to be stirred, after stirring 40-60s, add and the water of above-mentioned raw materials quality proportioning
It is stirred, obtains preliminary compound；
(3) discharging: under room temperature state, adds remaining 1/3 and mixes in the preliminary compound formed in the step (2)
Additive, the water being simultaneously introduced equal in quality proportioning is stirred, and forms final compound and go out after stirring 80-100s
Material；
(4) deposit and reprocess: the final compound formed in step (3) is placed on shady and cool local 10-15 days be dried
Rear taking-up, at the silica flour serosity of its surface smear 5%-10%, until it completely into after compound, is paved and is placed on too
After being exposed to the sun 1-2 hour under sun, form celluar concrete.
Further, in the preliminary mixing of step (2) raw material, under room temperature state, by process later half regeneration aggregate,
Slag, cement according to the ratio of 4:2:1 put into stirring container in mix, and add half polypropylene film-fibre, sand with
And 1/3 additive mixed, it is subsequently added the water with above-mentioned raw materials quality proportioning and is stirred, after stirring 40-60s, then
Add the water with above-mentioned raw materials quality proportioning to be stirred；Material surface-stable to be mixed, after floating thing, adds remaining one again
Regeneration aggregate partly, slag, cement are put into according to the ratio of 4:2:1 and are mixed to stirring container, and add half polypropylene screen
Split the additive that fiber, sand and 1/3 mix, be subsequently added the water with above-mentioned raw materials quality proportioning and be stirred, stirring
After 40-60s, add the water with above-mentioned raw materials quality proportioning and be stirred, and obtain preliminary compound；Wherein, second
During secondary stirring, the temperature of added water is 40-50 DEG C.
Further, during step (4) is deposited and reprocessed, the final compound formed in step (3) is put
Putting and take out behind local 10-15 days that cool place is dried, at the silica flour serosity of its surface smear 8%, the temperature of silica flour serosity is 30-
40 until it completely into after compound, paved and be placed on after being exposed to the sun 1-2 hour under the sun, formed porous coagulation
Soil.
Contrasting existing technology, in the formula of the present invention, the component of regeneration aggregate, slag and cement and mass ratio are
4:2:1；Described polypropylene fibre and the component of additive and mass ratio are 1:1；The proportioning of above-mentioned quality ensure that mixed
Can each component can be sufficiently mixed during conjunction, in order to control in preparation process, the most unnecessary foreign material will not be produced.With
Time, in formula, add polypropylene fibre, improve the tensile strength of the celluar concrete prepared；Meanwhile, add in formula
Additive, including high efficiency water reducing agent, bentonite, caoutchouc latex, thin iron powder, organic flocculant, improves concrete
PH-value, improves the performance such as ventilative, permeable of the celluar concrete prepared, and quickly condenses performance.
In raw-material preparation process, after regeneration aggregate pulverizes the granule for 30-40cm particle diameter, employing grating is simultaneously
10～20 vibrosieves are screened, and are sieved 2-3 time in the sieving time section gradually successively decreased, it is ensured that regeneration aggregate is each
The size of granule, it is simple to mixing, on this basis, water glass solution on the surface smear of regeneration aggregate, improve its surface and
Internal intensity；Secondly, the proportioning of raw material adds slag, is effectively increased the comprcssive strength of later stage celluar concrete.
In the preparation process of raw material, it is divided into twice mixing and adds additive, it is ensured that it can preferably merge
In concrete, it is ensured that the stability of its performance.And mix twice stirring, taking out after drying, and be again coated with on its surface
Smear the silica flour serosity of 8%, further ensure that comprcssive strength and the stability on its surface.
Proving through test of many times, in conjunction with formula and the preparation method of the present invention, the celluar concrete of the present invention meets and carries
The performance of celluar concrete and intensity in high national standard；Simultaneously as the use of additive, change the soda acid of concrete
Value, thus be plant environment needed for its pore interior grows, can be applicable to the ground such as green way bank protection and slope, roadside, have
The value of environmental protection widely.
