Structure, expanded metal lath used in architectural lay wire wall are directly produced in flakes by wall requirement for height in factory, can be poured after on-site consolidation
Concrete is built, multilayer and small sized multiple story building are widely used in.Wall is after casting concrete, and expanded metal lath does not have to remove, and abandoning is put in
In wall, many workloads are reduced, while increasing strength of wall body.The concrete poured in architectural lay wire at present is conventional Self-leveling
Shang Tong is easy isolation, and live civilized construction is poor, and sandstone, cement price amount of increase are very big in the market, at high cost, is unfavorable for building mould
The popularization of web frame, heat insulating and sound insulating effect are undesirable.Chinese patent 1624269A discloses a kind of building model net wall structural element,
The template wall being arranged face-to-face including two, template wall is spaced apart and folded and ground is connected to one by two for articulated joints
It rises, it is characterised in that：One template wall is expanded metal lath, another template wall is light composite board, and light composite board is silicon
One of sour calcium plate, fiber cement board, lightweight lime plate, fire-proof plate, the advantage is that and improve wall by light composite board
Fire prevention, heat preservation, sound insulation value；But the great in constructing amount of one layer of light composite board is set outside wall, wall integrity can be compared with
Difference.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of architectural lay wire Self-leveling regeneration lightweight aggregate concrete and its preparation
Method, the architectural lay wire Self-leveling regenerate lightweight aggregate concrete high-strength light, the spy for having fire prevention, heat preservation, soundproof effect good
Point, and Self-leveling does not isolate, and reduces construction volume, shortens construction period, it is light that regeneration made of building waste recycling is contained in raw material
Aggregate reduces cost, significantly adverse effect of the mitigation building waste to environment.
To achieve the goals above, the present invention provides a kind of architectural lay wire Self-leveling regeneration lightweight aggregate concrete, composition

Preferably, the cementitious material is made of cement and industrial residue micro mist, matter of the cement in cementitious material
Measuring percentage is 40~70%, and mass percent of the industrial residue micro mist in cementitious material is 30~60%；It is described
Cement is at least one of ordinary portland cement and pozzolan cement of label 42.5MPa or more；The industrial residue micro mist
For at least one of blast-furnace cinder micro-powder, gangue waste residue micro mist, iron tailings slag micro mist and Pb-Zn tailings slag micro mist.
Preferably, the regeneration lightweight aggregate is made of coarse aggregate and fine aggregate, the body of coarse aggregate in the regeneration lightweight aggregate
Product percentage is 20~70%, and the percentage by volume of fine aggregate is 30~80% in the regeneration lightweight aggregate；The coarse aggregate heap
Product bulk density screening range is 300~800kg/m3, partial size is 3~8mm；Fine aggregate accumulation bulk density screening range is 50~
350kg/m3, partial size is 0.2mm~3mm；When prepared by the regeneration lightweight aggregate：By light-weight building refuse breaking and the appearance that screens out
It is not more than the aggregate of 800kg/m3 again, the coarse aggregate and fine aggregate of different-grain diameter and bulk density is then screened out, according still further to volume hundred
Coarse aggregate and fine aggregate are uniformly mixed and obtain regeneration lightweight aggregate by score.
Preferably, the partial size of the expanded vermiculite powder is 0.1mm~0.6mm, and density is 50~150kg/m3.
Preferably, the segregation reducing agent is compounded by gelatin and miberal powder, the mass ratio of the gelatin and miberal powder be (2~
2.5):1, the miberal powder is at least one of dolomite dust and magnesite powder.
Preferably, the thixotropic lubricant is montmorillonite powder and the powdery mixing that talcum powder example in mass ratio is mixed to get
Object, montmorillonite powder：Talcum powder is 3:1, montmorillonite powder partial size is 0.2~5 μm, and talcum powder partial size is 20~100 μm.
Preferably, the physical blowing agent is at least one of colophonium pyrolytic polymer and polyethoxylated fatty alcohols.
Preferably, the foam stabilizer is sodium sulfate of polyethenoxy ether of fatty alcohol；The water-reducing agent is liquid aliphatic hydroxyl
