Abstract
The invention discloses multifunctional foam concrete. Aggregate of the foam concrete contains kieselguhr which has heat preservation and sound insulation performance, so that the aggregate and sealed air holes of the multifunctional foam concrete both have heat preservation and sound insulation performance, and the foam concrete has good heat preservation and sound insulation performance in the condition of keeping high strength.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of light foaming concrete.
Background technology
Foamed concrete; Have another name called foamed concrete or light weight concrete; Foamed concrete is that the foamed system through foaming machine fully foams whipping agent with mechanical system; And with foam and grout uniform mixing, the pumping system through foaming machine carries out cast-in-place construction or mould molding then, through the formed a kind of novel light lagging material that contains a large amount of sealed porositys of natural curing.The inner sealed porosity of foamed concrete makes it have performances such as insulation, sound insulation; The aggregate of foamed concrete forms by theing cement solidifies, and insulation, the sound-proofing properties of aggregate itself are poor.Can only improve insulation, the sound-proofing properties of foamed concrete through the content that increases sealed porosity, but the increase of sealed porosity will inevitably cause the intensity of foamed concrete to reduce, promptly the intensity of foamed concrete is oppositely relevant with its insulation, sound-proofing properties.
Summary of the invention
The object of the present invention is to provide a kind of multi-functional foamed concrete; The aggregate of this multi-functional foamed concrete itself all has good heat preservation and soundproof performance with its inner sealed porosity; When making multi-functional foamed concrete have higher heat preservation and soundproof performance; Can also have higher intensity, and can purify air.
Multi-functional foamed concrete of the present invention comprises the sealed porosity that the cement based aggregate is inner with being distributed in said aggregate, contains zeyssatite in the said aggregate.Further, diatomaceous content is 10%-50% in the said aggregate.The aforementioned cement base aggregate is meant by cement slurry or the main concretionary aggregate of slurry that is made up of cement; Include and promptly form cement zeyssatite aggregate after cement and diatomaceous slurry solidify.
Because zeyssatite (staple is a silicon-dioxide) itself has good insulation, sound-proofing properties; In the aggregate of foamed concrete, add zeyssatite; Make aggregate itself have good heat preservation and soundproof performance; Aggregate and sealed porosity all have good heat preservation and soundproof performance like this, when can make foamed concrete keep good heat preservation and soundproof performance, can also have higher intensity.In addition, that zeyssatite also has is fire-retardant, objectionable impurities (like formaldehyde, benzene and toluene) in the absorbed air, produce performance such as negative ion, make foamed concrete of the present invention have fire-retardant, function such as purify air.Zeyssatite and cement are jointly as the aggregate of foamed concrete; Embody best fit; Make foamed concrete can embody the function of zeyssatite and cement; Be lightweight, fire-retardant, sound insulation, noise reduction (absorption noise), waterproof, heavy metal-passivated, absorption toxic substance, even the sexavalence cadmium is also had adsorption function, making originally, the light-weight foamed concrete has self-cleaning function.
Embodiment
Through embodiment, multi-functional foamed concrete of the present invention is described further below.
Foamed system through foaming machine fully foams whipping agent with mechanical system; And with foam and cement and diatomaceous mixed slurry uniform mixing; Pumping system through foaming machine carries out cast-in-place construction or mould molding then, just forms multi-functional foamed concrete of the present invention through natural curing.Aforementioned cement and diatomaceous mixed slurry are to be mixed with water and stirred the slurry that forms of back by cement and zeyssatite mixture; Wherein diatomaceous weight percent can be 10%, 20%, 30%, 40% or 50% in cement and the zeyssatite mixture.
In multi-functional foamed concrete of the present invention, aggregate is solidified by cement and zeyssatite and forms.Because of zeyssatite itself has good insulation and sound-proofing properties, aggregate also just has certain heat preservation and soundproof performance, and the heat preservation and soundproof performance of this foamed concrete is not only determined by the content of sealed porosity; When this foamed concrete has good heat preservation and soundproof performance, can also have than higher intensity.Compare with not containing diatomaceous foamed concrete, under the identical situation of air vent content, contain diatomaceous foamed concrete and have better heat preservation and soundproof performance; Under the identical situation of heat preservation and soundproof performance level, it is lower to contain diatomaceous foamed concrete air vent content, has higher intensity.
Obviously, the foregoing description only be for convenient, clearly explain that technical scheme of the present invention does for example, and be not limitation of the present invention.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make the variation or the conversion of various ways; Be equal to mutually with the present invention or any variation of substantial equivalence or conversion all are among protection scope of the present invention.
Claims (2)
1. a multi-functional foamed concrete comprises the sealed porosity that the cement based aggregate is inner with being distributed in said aggregate, it is characterized in that containing zeyssatite in the said aggregate.
2. multi-functional foamed concrete according to claim 1 is characterized in that diatomaceous content is 10%-50% in the said aggregate.
