Abstract
The preparation method of a kind of impervious aerated-block disclosed by the invention, comprises the following steps: that (1) carries out raw material according to the weight portion of component and prepares；(2) being stirred making slip in above-mentioned raw material first adds cast blender, add appropriate silicone oil, after adding silicone oil, blender need to carry out strong stirring；(3) concrete slurry obtained by step (2) is cast in mould, carries out precuring, treats that idiosome reaches certain degree of hardness, can cut into building block base；(4) building block base is sent into steam press maintenance in still, prepare finished product.The beneficial effects of the present invention is: the aerated-block mixing silicone oil is completely soaked in water 30 days, all pores of aerated-block are all without any water stain existence, and aerated-block solid masses differs less than 2%, it is completely soaked in water after 45 days, water penetrates into aerated-block 1cm, being completely soaked in water 60 days, water penetrates into aerated-block 1.5cm, but on aerated-block bubbles through the water column in immersion process always.
Description
Technical field
The present invention relates to the preparing technical field of air-entrained concrete building block, particularly relate to a kind of impervious aerating and build
The preparation method of block.
Background technology
Air-entrained concrete building block to the penetration and promotion in the whole world and use, has obtained environmental administration of various countries Zi invention
Accreditation consistent with builder.But owing to ordinary air-entrained concrete is by cement, silica sand, quick lime, stone
Cream etc. are made, and various places weather is different, and rainy season as local in some is longer, and air humidity is big, thus
Result in the water suction that air-entrained concrete building block is the most undue in application process, cause air-entrained concrete building block
Can occur the phenomenon that contraction is excessive occur after the drying, and frost resistance is poor, natural differentiation is very fast.Therefore,
It is badly in need of air-entrained concrete building block technology is studied further so that further meet wanting of market
Ask.
Summary of the invention
The technical problem to be solved: provide one to be applicable to for the deficiencies in the prior art
Various places Different climate and the preparation method of contraction change is little, anti-freezing property is excellent antiseepage aerated-block.
Technical problem solved by the invention can realize by the following technical solutions:
The preparation method of a kind of impervious aerated-block, comprises the following steps:
(1) carry out raw material according to the weight portion of following component to prepare: cement 7～11 parts, Calx 26～35
Part, silica sand 50～70 parts, aluminium powder 0.5～1.1 parts, foam stabilizer 0.05～0.3 part, Gypsum Fibrosum 2～6 parts
And appropriate water；
(2) it is stirred making slip in above-mentioned raw material first adds cast blender, adds appropriate
Silicone oil, the consumption of silicone oil is the 0.6%～2% of cement consumption, is adding after silicone oil, and blender need to be carried out
Strong stirring no less than 3 minutes；
(3) concrete slurry obtained by step (2) is cast in mould, by temperature be 45～
Carry out under 65 DEG C of environment precuring 2～3 hours, treating that idiosome reaches certain degree of hardness, building block base can being cut into；
(4) building block base being sent into steam press maintenance in still, steam pressure is 1.4～1.7Mpa, steams the oxygen time
It is 5～6 hours, prepares finished product.
In a preferred embodiment of the invention, described silicone oil is KF-4003.
Owing to have employed technical scheme as above, the beneficial effects of the present invention is: mix the aerating of silicone oil
Building block is completely soaked in water 30 days, and all pores of aerated-block are all without any water stain existence, Er Qiejia
Gas building block solid masses differs less than 2%, is completely soaked in water after 45 days, and water penetrates into aerated-block 1cm,
Being completely soaked in water 60 days, water penetrates into aerated-block 1.5cm, but aerated-block is in immersion process one
On directly bubbling through the water column.
