Description

Foam concrete brick with card cap

Technical field

This utility model relates to a kind of construction material, particularly relates to a kind of foam concrete brick with card cap.

Background technology

Foam concrete is that foaming agent is the most fully foamed by the foamed system by foaming machine, and by foam with Cement mortar uniformly mixes.The pumping system being then passed through foaming machine carries out cast-in-place construction or mould molding, through natural curing institute shape A kind of novel light insulation material containing a large amount of sealed porositys become.Foam concrete brick is typically to by main to sand, flyash etc. material Adding cement, foaming agent, the stirring of water reducer etc. material mixes, then that mixture is compressing, by maintenance etc. operation Finally support finished product.By adding the materials such as foaming agent, a large amount of sealed porosity can be formed in material.Sealed porosity can rise To reducing brick body density, increase brick body sound insulation, warming effect etc..

Concrete, foam concrete brick can possess advantages below:

1. lightweight: the density of foam concrete is less, and density rating is generally 300-1800kg/m, conventional foam coagulation The density rating of soil is 300-1200 kg/m3, density is that the ultralight foam concrete of 160 kg/m3 is also in architectural engineering Obtain application.Owing to the density of foam concrete is little, in building structure such as the external and internal wall of building, aspect, flooring, columns This kind of material of middle employing, typically can make building deadweight reduce about 25%, and some is up to the 30%-40% of works gross weight.And And, for structural elements, as used foam concrete to replace normal concrete, the bearing capacity of component can be improved.Therefore, exist Architectural engineering use foam concrete have significant economic benefit.

2. foam concrete heat-preserving is heat insulation: owing to containing a large amount of tiny holes closed in foam concrete, therefore have Good thermal property, the best thermal and insulating performance, this is not available for normal concrete.Generally density rating exists The foam concrete of 300-1200 kg/m3 scope, heat conductivity is between 0.08-0.3w/ (m K), and thermal resistance is about common mixed 10-20 times of solidifying soil.Use foam concrete as building masonry wall and roofing, there is good energy-saving effect.

3. foam concrete sound-proof refractory: foam concrete genus polyporus material, therefore it is also a kind of good sound insulation material Material, can use this material as puigging at the floor of building and the top layer etc. of the baffle of highway, underground structure. Foam concrete is inorganic material, will not burn, thus has good fire resistance, uses, can improve building on building The fire protecting performance of thing.

4. foam concrete overall performance: can construct by cast-in-site, be tightly combined with major project.

5. foam concrete low bullet damping: the porous of foam concrete makes it have low elastic modelling quantity, so that its Impact loading has good absorption and dispersion.

6. foam concrete good waterproof performance: cast-in-place foamed concrete water absorption rate is relatively low, relatively independent CAB and good Good globality so that it is there is certain water resistance.

7. foam concrete is easy to process: foam concrete not only can produce into various goods in factory, and Can also site operation, direct cast-in-place one-tenth roofing, ground and body of wall.

8. the foam concrete feature of environmental protection is good: foam concrete needed raw material is cement and foaming agent, and foaming agent is the most close Neutrality, without the harmful substance such as benzene, formaldehyde, it is to avoid environmental pollution and hidden fire-fighting danger.

9. foam concrete easy construction: only cement foam maker need to be used can to realize automated job, pumpable realization is hung down The long-distance sand transport of straight height 200 meters, workload is 150 300 cubes/working day.Foam concrete also has work progress Middle pumpability is good, and comprcssive strength is high (0.5-22.2Mpa), and impact energy absorption characteristic is good, can utilize industrial residue, price in a large number The advantage such as cheap.

10. material environment friendly: do not contain the nuisance such as benzene, formaldehyde, "dead" material.

But, the foam concrete brick of prior art ftractures the most after the drying, simultaneously because there is a large amount of sealed porosity in it, Its overall structure is not sufficiently strong.The overall appearance structure of foam concrete brick requires further improvement simultaneously.

Summary of the invention
