Description

A kind of high tenacity aerated bricks and preparation method thereof
Technical field
The invention belongs to brick field, particularly relate to a kind of high tenacity aerated bricks and preparation method thereof.
Background technology
Aerated bricks is also called air-entrained concrete building block, application very extensive, is mainly used in the load-bearing wallings such as the materials for wall in machinery plant and covil construction, infilled wall, floor and roof boarding and non-bearing material and filling enclosure wall around.
Current aerated bricks has become the leading product of building material industry, and country progressively prohibits the use clay solid brick, is instead exactly air-entrained concrete building block gradually, autoclaved brick.
Aerated bricks have lightweight, thermal and insulating performance good, shock resistance is strong, good processability, have certain high thermal resistance, good, the adaptable feature of sound-proofing properties, can according to the different starting material in locality, different condition is carried out amount body and is surely made, raw material sources is extensive, river sand, flyash, ore in sand form etc. can be selected, suit measures to local conditions, can be salvaged, environmental, really turn waste into wealth.
But along with the development of building trade, buildings is more and more higher, moulding is more and more peculiar, require all to increase to the intensity, density, shrinkage value, frost resistance etc. of aerated bricks, improving constantly in addition along with people's living standard, also more and more higher to the requirement of environment, there is higher requirement to the heat-insulating property of buildings, sound absorption qualities, radioactivity, even require that buildings has the performance of body health benefits, therefore as required, the aerated bricks developing excellent performance is more imperative.
Summary of the invention
The object of the present invention is to provide a kind of high tenacity aerated bricks and preparation method thereof, this aerated bricks intensity be high, good toughness, wear resistance is good, and heat retaining property is good, and soundproof effect is good, also has excellent erosion resistance and fire resistance.
