A kind of novel light insulation material containing a large amount of sealed porositys is formed by through natural curing.It belongs to air bubble-shaped heat insulating material
Material, outstanding feature is to form closed foam hole in inside concrete, makes concrete light and thermal insulation separation thermalization；It is also simultaneously
A special kinds in air entrained concrete, its pore structure and material property all close to air entrained concrete, both theys'
Difference, the only difference between stomata shape and aerating means, air entrained concrete stomata is usually ellipse, and foam is mixed
Solidifying soil is influenced by pore effect, is deformed, and forming polyhedron air entrained concrete is to pass through chemistry using chemical gas generation
Reaction generates gas by inside and forms stomata, and lightweight concrete is then that first foaming agent is made up of the method for mechanical system bubble
Foam, then again by foam be added cement, magnesite, in calcium plaster, form foam slurry, then through natural curing steam curing and
At.
Existing foam concrete during the preparation process, needs repeatedly to be added foaming agent and generates foam, wait combination reaction
It is middle to generate a large amount of gas, so that slurry is generated a large amount of bubble, becomes foam concrete, this production method is to production equipment
It is more demanding, need staff rule of thumb to select the repeatedly time of addition foaming agent and dosage with response situation, to increase
The foaming effect of strong foaming agent, therefore be easy to cause shadow to foaming effect due to the difference of foaming agent additive amount and addition time
It rings, defect occurs so as to cause the foam concrete quality of final molding, simultaneously because foaming agent is added after slurry mixing
, after being added into slurry, easily coated by slurry, become dry powder block, can not with slurry dispersion mixing, thus can not be well
Foaming effect is played, therefore had both caused the waste of applied foam agent, also the quality of foam concrete after molding is caused not
Benefit influences.
