Abstract
The invention discloses a kind of fly ash aerated with aluminium powder cream and preparation method thereof. Is raw material by following parts by weight made: aluminium foil 180, white sugar 3, glycerine 4, silicone oil 0.25, stearic acid 4.5, triazole 0.5, TS-10? 4.5 water 300. Compared with prior art, aluminium powder cream of the present invention is got angry evenly in fly ash aerated, gas forming amount is suitable, through production test, rarely has the mould of collapsing to occur, and has improved the qualification rate of aerated blocks.
Description
Technical field
The present invention relates to a kind of fly ash aerated and use aluminium powder cream, belong to concrete field of new.
Background technology
The concept of air entrained concrete is taking siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement) as primary raw material, admixture foaming agent (aluminium powder), the light porous silicate product of making by technical process such as batching, stirring, cast, precuring, cutting, steam pressure, maintenances. Because it contains a large amount of even and tiny pores, therefore named air entrained concrete after getting angry.
At present, aerated blocks has an insoluble technical problem in producing, and the aerated blocks mould rate of collapsing is higher, causes aerated blocks qualification rate in 80% left and right, the main cause of the mould that causes collapsing be exactly existing aluminium powder cream get angry weak effect, get angry inhomogeneous. Through the retrieval in Chinese patent literature, find no the record of this aspect.
Summary of the invention
The invention provides a kind of fly ash aerated and use aluminium powder cream, solve the aerated blocks higher problem of mould rate of collapsing.
Technical scheme of the present invention is:
Use aluminium powder cream, made by the raw material of following parts by weight: aluminium foil 180, white sugar 3, glycerine 4, silicone oil 0.25, stearic acid 4.5, triazole 0.5, TS-104.5 water 300 for a kind of fly ash aerated.
A fly ash aerated preparation method with aluminium powder cream, comprises the following steps successively:
1) ball milling powder after aluminium foil fragmentation is broken into 200 object aluminium powders;
2), in parts by weight, aluminium powder 180, white sugar 3, glycerine 4, silicone oil 0.25, stearic acid 4.5, triazole 0.5, TS-104.5 water 300 are mixed;
3) to step 2) form slurry carry out press filtration, press filtration to the mass percent of moisture content is 20 ~ 40%;
4) filter cake step 3) being formed is broken up, and after material scatters, packs.
Compared with prior art, aluminium powder cream of the present invention is got angry evenly in fly ash aerated, gas forming amount is suitable, through production test, rarely has the mould of collapsing to occur, and has improved the qualification rate of aerated blocks.
Detailed description of the invention
Below by specific embodiment, the present invention will be further described.
Embodiment 1
A fly ash aerated preparation method with aluminium powder cream, comprises the following steps successively:
1) ball milling powder after aluminium foil fragmentation is broken into 200 object aluminium powders;
2), in parts by weight, aluminium powder 180, white sugar 3, glycerine 4, silicone oil 0.25, stearic acid 4.5, triazole 0.5, TS-104.5 water 300 are mixed;
3) to step 2) form slurry carry out press filtration, press filtration to the mass percent of moisture content is 20 ~ 40%;
4) filter cake step 3) being formed is broken up, and after material scatters, packs.
Embodiment 2
A kind of raw material proportioning of fly ash aerated is made up of the material of following parts by weight: 50 parts, flyash, 22 parts, lime, 20 parts, gypsum, 20 parts of the aluminium powder cream of embodiment 1,60 parts, water;
Its processing step is:
1) raw material disposal: get raw material according to proportioning, flyash is delivered to after ball mill is levigate to slurry tank and stored; Lime is sent into ball mill after jaw crusher carries out fragmentation, send in powder batch bin after levigate; Gypsum is made to the solution of the 30-36% of mass percentage concentration, sent in storage tank and store; Aluminium powder is added water to stir and make aluminium powder suspension;
2) moulding by casting: each material that step 1) is obtained is placed in mixer, and adds appropriate mixing water, by die casting, then sends into and just supports the storehouse initial set of getting angry after mixing, and cuts into adobe after just forming type, obtains cutting aftershaping adobe;
3) steam-cured: by step 2) the cutting aftershaping adobe that obtains is placed in still kettle, and under 1.24MPa saturated vapor, maintenance goes out still for 12 hours, obtains air-entrained concrete building block.
In aerated blocks production process, do not find to collapse mould phenomenon.
All simple distortion of making in the situation that not departing from core of the present invention or amendment all fall into protection scope of the present invention.
