Description
Technical field
Application field is made the invention belongs to air entrained concrete, and in particular to a kind of shaping made for air entrained concrete
Equipment and its method of work.
Background technology
Air entrained concrete is a kind of new wall material, and it is unique in that it is a kind of very light-duty insulation
Heat-insulated novel building walling.Before air entrained concrete technology starts from 100 years, and the ratio that this technology of China starts is later, than
Foreign countries have totally fallen behind 40 years, but, the development of the air entrained concrete industry of China is strictly very fast.It is now domestic
Air entrained concrete technical matters level can reach international most advanced level.
Air entrained concrete sharpest edges are exactly to economize the land resource, without wasting substantial amounts of arable land, and its raw material
Very extensively, dust and sand, slag, flyash and gangue etc. are all the raw material for doing air entrained concrete in source.And aerating
The performance characteristics of concrete are very superior, have it is extraordinary can working ability and heat-insulated and insulating power, and plasticity
It is very strong, can Bao can saw, have extraordinary processing characteristics.
The application of air entrained concrete widely, is used primarily in materials for wall, filling in machinery plant and civil buildings
The filling enclosure wall of the load-bearing such as wall, floor and roof boarding walling and non-bearing material and surrounding.
Gradually, air entrained concrete has turned into the leading products of building material industry, and country is now to clay solid brick
Carry out forbidding stopping production, be instead exactly gradually air-entrained concrete building block, steam-pressing brisk.
The application of air entrained concrete alleviates present situation, because it is fine coal to make air-entrained concrete building block raw material
Ash, dust and sand, gangue, industrial residue etc., the big rubbish for both being from thermal power plant and artificial coal in source of these raw materials, are not having
Before having air-entrained concrete building block equipment, the flyash that former power plants generating electricity is emitted all has carried out burial treatment, does not all have
Have and pay attention to its value, nowadays the application of the equipment substantially increases waste economic circulation, and is buried in underground in the past
Flyash be re-used again, along with various regions government department to air entrained concrete industry trip encouragement policy and help political affairs
Plan, so the development prospect of air-entrained concrete building block industry is very wide.
