Description

The concrete aerated light block of rice husk steam pressure and production method thereof

Technical field

The present invention relates to a kind of production method of steam pressure autoclaved lightweight concrete.

Background technology

Autoclave aerated concrete building block is made primarily of cement, lime, gypsum, flyash, aluminium powder etc., there is intensity lower, the defect that cost is higher.Also do not have at present to be a kind ofly beneficial to the steam pressure concrete aerated light block of rice husk as raw material production.

Summary of the invention

The object of this invention is to provide the concrete aerated light block of a kind of rice husk steam pressure and production method thereof, the building block light weight of production, intensity, higher than traditional building block about 20%, has water-impervious function simultaneously.

Technical scheme of the present invention is as follows:

The concrete aerated light block of a kind of rice husk steam pressure, is characterized in that: be made up of the raw material of following weight part: unslaked lime 100-110, cement 60-70, aluminium powder 1-2, plaster stone 10-15, stone flour 5-8, blast-furnace slag 10-20, rice husk 30-40, rice bran 20-30, soybean oil residue 4-6, clorafin 1-2, Starso 3-5, flour 4-5.

The production method of the described concrete aerated light block of rice husk steam pressure, is characterized in that comprising the following steps:

(1), by flour add in suitable quantity of water, boil into paste liquid, add soybean oil residue wherein, be heated to 80-90 DEG C, dispersed with stirring 10-20 minute, then add rice husk, rice bran, Starso wherein, be constantly stirred to Starso and dissolve, become thick pulpous state;

(2), by unslaked lime, cement, plaster stone, stone flour, blast-furnace slag mixing, be added to the water, stir, then add thick slurry and aluminium powder, clorafin wherein, mix 30-40 minute;

(3), then injection molding, foaming, precuring 1 ~ 2.5 hour;

(4), enter steam press maintenance, be cooled to finished product.

The present invention adopts oil foot as raw material, adds the water resistance of building block, and meanwhile, rice husk, rice bran alleviate building block weight, and increase heat-insulating property, after testing, block strength reaches 3.6Mpa.

Embodiment

The concrete aerated light block of a kind of rice husk steam pressure, be made up of the raw material of following weight part (kilogram): unslaked lime 100, cement 70, aluminium powder 2, plaster stone 15, stone flour 5, blast-furnace slag 20, rice husk 30, rice bran 30, soybean oil residue 4, clorafin 2, Starso 3, flour 5, water is appropriate.

Production method, comprises the following steps:

(1), by flour add in suitable quantity of water, boil into paste liquid, add soybean oil residue wherein, be heated to 80-90 DEG C, dispersed with stirring 10-20 minute, then add rice husk, rice bran, Starso wherein, be constantly stirred to Starso and dissolve, become thick pulpous state;

(2), by unslaked lime, cement, plaster stone, stone flour, blast-furnace slag mixing, be added to the water, stir, then add thick slurry and other raw material such as aluminium powder, clorafin wherein, mix 30-40 minute;

(3), then injection molding, foaming, precuring 1 ~ 2.5 hour;

(4), enter steam press maintenance, be cooled to finished product

Building block aperture surface area of the present invention is about 40-50m ²/ kg, is widely used in industry and the inner-outer wall of covil construction and roofing, can cuts with cast-in-place, framework, frame, the multiple architecture structure form such as steel construction is combined.This product after testing its ultimate compression strength mean value is 3.5Mpa.
