Description
Technical field
The present invention relates to building thermal insulation material field, more particularly to a kind of foamed concrete thermal-insulating material.
Background technology
Foam concrete is most widely applied early in American-European countries such as the U.S., Britain, Holland, and China is also increasingly
Pay attention to Building Energy-saving Work, in recent years, the research and development of foam concrete are all paid much attention to both at home and abroad, foam concrete is with it
Lightweight, thermal and insulating performance are good, sound-proof refractory is good, foam concrete also has that pumpability is good, waterproof ability is strong, in regulation room
Humidity, can largely utilize industrial residue the advantages of, be widely used rapidly.
Foam concrete is mainly to be made up of calcareous material and siliceous material, but density reduction while thermal conductivity factor also with
Reduction.And excessive density it is too low when, the integrality of foam concrete pore structure can be destroyed again.Foam concrete heat-preserving material
It is Binder Materials that material mainly uses sulphate aluminium cement, ferrous aluminate cement, when this is primarily due to such cement setting hardening
Between the development of short, early strength it is fast, it is good with gas production rate uniformity that it condenses hardening rate.But its price is higher, and this kind of
, less than Portland cement product, during particularly for external wall, product service life can be big for the durability of cement products
It is big to shorten.
And it is also common fault that current cellular concrete product is present that water absorption rate height is, too high water absorption rate can cause foam to mix
Coefficient of softing, frost resistance, service life of solidifying soil product etc. are remarkably decreased, and greatly hinder being applied clinically and popularized for foam concrete.
At present, feasible solution is when to select effective efficiency additive by suitable cooperation, to above mentioned problem
It is improved.
The content of the invention
It is an object of the invention to provide a kind of foamed concrete thermal-insulating material, with good mechanical property, insulation
Performance and water resistance, cost-effective solution problems of the prior art.

Further, the slag powders are S95 grades of ground blast furnace slag powder.
Further, the diameter of the river sand is between 0.5~2mm.
Further, the diameter of the fiber is between 5~12mm.
Further, the fiber uses polypropylene fibre or short glass fiber.
Further, the coagulant uses sodium metaaluminate.
Further, the water reducer uses the aqueous water reducer of polycarboxylic-acid.
Further, the waterproofing agent uses odium stearate or aquation dicalcium silicate.
The present invention compared with prior art, has the advantages that：
(1) foamed concrete thermal-insulating material of the invention is reasonably combined by each component, with good mechanical property,
Thermal and insulating performance and water resistance；Especially medium density, heat-insulating property is good, and thermal conductivity factor is low.
(2) all there is certain shrinkage in cement products, and slag powders can reduce the adiabatic temperature rise of concrete, reduce mixed
The dry-shrinkage deformed and time deformation of soil is coagulated, volume stability is improved.Feldspar powder, river sand, fiber can improve product shear strength,
Rupture strength and wearability.
(3) gypsum not only can shorten setting time, while early strength can also be improved.
(4) foam stabilizer can significantly improve the foam structure of foam concrete, its inner cell is become tiny, size equal
First, spherical degree is high, connected ratio reduction between abscess.
(5) the foaming agent foaming that the present invention is used is fast, and foam volume is big, but it is more difficult to deposit bubble, less stable, but coordinates
After above-mentioned foam stabilizer, ensure bubble it is many, foaming soon in the case of, deposit bubble rate and also significantly improve.
(6) it is raw material that Portland cement is selected in the present invention, when coagulant can effectively overcome it to condense hardening
Between slow shortcoming.
(7) water reducer can significantly reduce the slurry ratio of mud in the case of foam concrete slurry workability identical is ensured.
Aqueous polycarboxylate water-reducer is used to reduce and condense firm time with reduces cost, dispersion efficiency can also be far above dry powder-shaped system
Agent, reduces mixing water amount, improves the consistency of cell wall.
(8) it is to reduce that foam concrete water absorption rate is most effective, easily method to add waterproofing agent, can significantly improve sample
Water resistance and it has good adaptability with low density foam concrete system, will not only destroy bubble when being directly incorporated into
Pore structure is acted on certain foam stabilizing on the contrary.
