Description
Technical field
The invention belongs to brick field, relate in particular to a kind of high temperature resistant aerated bricks and preparation method thereof.
Background technology
Aerated bricks is also called air-entrained concrete building block, application very extensively, be mainly used in load-bearing walling and non-bearing material and the filling enclosure walls around such as materials for wall, infilled wall, floor and roof boarding in mechanical factory building and civil buildings.
Aerated bricks has become the leading products of building material industry at present, and country has progressively banned use of clay solid brick, is exactly instead air-entrained concrete building block gradually, steam-pressing brisk.
That aerated bricks has is lightweight, thermal and insulating performance good, shock resistance is strong, good processability, have certain heat-resisting quantity, good, the adaptable feature of sound insulation value, can be according to the different raw material in locality, different condition is carried out amount body and is surely made, raw material wide material sources, can select river sand, flyash, ore in sand form etc., suit measures to local conditions, can be salvaged, environmental, really turn waste into wealth.
But along with the development of building trade, building is more and more higher, moulding is more and more peculiar, the requirements such as intensity to aerated bricks, density, shrinkage value, frost resistance all increase, improving constantly along with people's living standard in addition, requirement to environment is also more and more higher, and the heat-insulating property to building, sound absorption qualities, radioactivity have higher requirement, even requires building to have the performance of body health benefits, therefore as required, develop the aerated bricks of excellent performance more imperative.
