Description
Technical field
The present invention relates to construction correlative technology field more particularly to a kind of special air entraining agents of stable structure type cement.
Background technology
Concrete air-entrainer can be effectively improved the workability of concrete, reduce bleeding performance, while substantially improving mixed
The freeze proof anti-permeability performance for coagulating soil, is suitable for the important engineering concrete structure such as airport, harbor work and bridge, severe cold area is spread
Concrete Highway, the bridge of cryosel are even more important.In addition, usually being mixed as activity using flyash in the configuration of these concrete
And material, to improve the workability of fresh concrete, and reduce the warm contracting cracking trend of mass concrete.But application is found, portion
Divide the higher flyash of loss on ignition because containing unburned carbon granules, usually reduces the bleed effect of air entraining agent.
In commerical ready-mixed concrete, the good air entraining agent of performance is remarkably improved plastic concrete and maturing
Properties, and the cost of additive and concrete can also be reduced.The research and application of excellent air entraining agent are China's coagulations
And its needs and certainty of additive development, exploitation, the promotion and application of air entraining agent are of far-reaching significance, should be Future Development high-performance
The indispensable additive of concrete.However mostly presence introducing bubble structure is unreasonable, is unevenly distributed, bubble shakiness for existing air entraining agent
Fixed, the deficiencies of size is improper, cannot effective fresh concrete workability, and improve the durability of maturing, with
The plyability of other concrete admixtures is poor.
