Abstract
The invention discloses an airentrained concrete, which is characterized by the following: adopting powder coal ash as aggregate and cement, lime and plaster as glue stock; adding liquid hydroperoxide according to certain proportion as beating agent and foaming agent; controlling the entire cost within lower scale.
Description
Technical field
The present invention relates to a kind of concrete, especially gas concrete.
Background technology
Present gas concrete has CN03112888.2 " a kind of novel gas concrete ": a kind of novel gas concrete, its major ingredient are stone flour, and concrete prescription is: stone flour 50-70%; Cement 1-10%; Lime 20-40%; Aluminium powder 5-12 ‰.The present invention makes full use of the stone flour waste residue, replace flyash or sandstone, turn waste into wealth, the novel gas concrete of making is of fine quality, cost is low, and alleviated the pressure of stone flour waste residue effectively to ecological environmental pollution, thoroughly eradicate stone flour and pollute, for stone production sustainable development already creates favorable conditions.
Present aluminium powder price maintenance is between ten thousand yuan/ton of 2.1-2.5, and the aluminium powder of light 5-12% just makes concrete produce the cost of 100-200 unit/ton like this, and the aluminium powder cost of possession reaches 70% like this, and is obviously uneconomical
Summary of the invention
Task of the present invention is the economy prescription of a kind of gas concrete of design.
Gas concrete of the present invention is to adopt the flyash in fuel-burning power plant as aggregate, and sizing material is a cement, lime, and gypsum, the companion goes into the liquid of certain proportion hydrogen peroxide as beating agent and foaming agent then.Because flyash, gypsum, lime all can have a certain proportion of output in the power station, so cost is relatively very low; And hydrogen peroxide at high temperature also can work the effect of reducing foaming, and can form all even bubble of not exchanging information.
It is main adopting the power station waste material, and adopts the hydrogen peroxide foaming, and hydrogen peroxide is per ton near 1500 yuan at present, and the energy cost control is in lower price.
Embodiment
We in the specific implementation, gas concrete is mainly used in and is made into prefabricated panels, building block, roof boarding etc., thus can be before mixing with the dehydration of gypsum system, can shorten the presetting period like this and quicken production efficiency.
Simultaneously the hydrogen peroxide ratio is regulated between 1.5-28% according to material and envrionment temperature.
In most cases, the optimum concn of hydrogen peroxide is between 5-9%.
Claims (4)
1. gas concrete, the flyash that it is characterized in that adopting the fuel-burning power plant is as aggregate, and sizing material is a cement, lime, gypsum, the companion goes into the liquid of certain proportion hydrogen peroxide as beating agent and foaming agent then.
2. gas concrete as claimed in claim 1 is characterized in that before mixing gypsum system being dewatered.
3. gas concrete as claimed in claim 1 is characterized in that the hydrogen peroxide ratio regulates between 1.5-28% according to material and envrionment temperature.
4. gas concrete as claimed in claim 1, the optimum concn that it is characterized in that hydrogen peroxide is between 5-9%.
