Energy saving building is more and more, improves the development level of building trade.Light solid composite wall plate is a kind of novel energy-saving ring
Material is protected, hereafter this is furtherd investigate.After measured, the weight of each unit area light solid composite wall plate is too late
The weight of two-sided plastering masonry after 120mm.So we can effectively reduce this material application in building structure
The weight of wall, and the bearing capacity of beam column can be reduced, interval can be played the role of in the construction process.Relative to common
Masonry structure for, it have biggish superiority.In the prior art, the building reinforced concrete lightweight wall material of production
Material is typically all to use electric heating or natural curing.The building reinforced concrete light weight wall produced such as electric heating or natural curing
Body material could dispatch from the factory after needing 28 days, and the production cycle is long, and the materials for wall uneven heating produced in this way is even, produce
Quality cannot ensure, seriously affect the turnover of production efficiency and fund.The purpose of the invention is to overcome the prior art
In shortcoming, a kind of simple process is provided, it is easy to process, cost compare lower, stable product quality, production efficiency compared with
The production method of high building reinforced concrete light wall material.
Summary of the invention
The object of the present invention is achieved like this:
A kind of production method of environmental-friendly walling material for building, comprising the following steps:
A, it is that a certain amount of sand first is added to be paved with blender bottom in the ratio in common prescription, is then initially added into gelling material
About 95% setting water is added in material, admixture and sand dry mixing 20-50s, stirs 20-60s；
B, water-reducing agent and foaming agent are added in 15-35s, is supplemented the water of residue 5%, stirs evenly, total time is not
3.5min can be less than；
C, in a mold after reinforcement placing skeleton, stirring is expected then to be vibrated, slot processed, plastering, obtained in feeding mold
Germule；
D, above-mentioned germule is placed in curing means and carries out steam curing, wherein the steam curing is included in 60-
Steam-cured 4-10 hours and steam pressure 6.5~11 hours at 0.7~1.2Mpa at 100 DEG C, it is described it is steam-cured be divided into it is quiet stop, heat up,
Constant temperature, cooling Four processes, the steam pressure are divided into boosting, constant pressure, decompression, cooling Four processes, by steam curing to obtain the final product
Light wall material.
Further, a method of building reinforced concrete New Type Light-weight Wall Material is produced, it is steam-cured in step d
The rate of ascending, descending temperature is 45 DEG C per hour in the process, and the rate of ascending, descending pressure is every during steam pressure described in step d
Steam used by steam curing is the waste vapour of power plant, steam curing institute in step d in half an hour 0.3.5 ± 0.2MP, step d
The steam used is the steam that is generated with boiler, and steam used by steam curing is the steam generated with boiler in step d, step
The high-mark cement that cementitious material described in rapid a is 43.5 grades or more, admixture described in step a are levigate high silica sand,
The mixture of one or more of the residue of slag micropowder, coal powder or concrete tubular pile.
Compared with prior art, beneficial effects of the present invention:
Using improving shaping speed and production efficiency after steam curing, due to the temperature and pressure of steam be it is controllable,
The a variety of materials of concrete are at high temperature under high pressure by adequately reaction, and product has high density, and high-intensitive performance makes it
The mechanical property of materials for wall is much higher than the construction(al)steel of electric heating or common maintaining production in terms of resistance to compression and horizontal force resistant
Reinforced concrete lightweight materials for wall.Such as electric heating or the building reinforced concrete light wall material of common maintaining production, need
It could dispatch from the factory after 28 days, and steam protecting method of the present invention only needs 20 hours or so to dispatch from the factory.Using steam-cured
Building reinforced concrete novel light wall material, properties are stablized, be will not cracking after installation.And common electric heating
Or natural curing is that intensity aspect is increasing with it, causes to hold in the state of no mould since a variety of materials are also changing
Easily-deformable, wall is easier to crack after installation.
