Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of preparation method of concrete foamer.
Background technique
Foamed concrete also known as foam concrete or lightweight concrete, foamed concrete are the foaming systems by foaming machine
System mechanically sufficiently foams foaming agent, and foam is uniformly mixed with cement slurry, then passes through the pumping system of foaming machine
System carries out cast-in-place construction or mold molding, is formed by a kind of novel light quality guarantee containing a large amount of sealed porositys through natural curing
Adiabator；Foamed concrete is double set continuous structures that organic binder is stirred into foaming agent, cement, flyash, mountain flour etc.
Polymer, include uniform stomata；Foamed concrete is to look for slope, ground insulating bed course for roof heat insulation, turn over beam foundation pit and fill out
It fills, the energy-saving materials such as wall pouring.Foaming agent aqueous solution is usually mechanically prepared into foam by foamed concrete, then
Foam is added in the slurry containing compositions such as siliceous material, calcareous material, water and various additives, is mixed, is poured
A kind of porous material made of molding, maintenance.Due to, containing a large amount of closed holes, being made it have following in foamed concrete
Good physical and mechanical property.1, the density of lightweight, foamed concrete is small, and density rating is generally 300-1800kg/m3, often
It is 300-1200kg/m3 with the density rating of foamed concrete.Since the density of foam concrete is small, it can generally make building
Self weight reduces by 25% or so, therefore, has significant economic benefit using foamed concrete in construction projects.2, thermal insulation separation
Good in thermal property, it is due to, containing a large amount of closed tiny holes, there is good thermal property in foamed concrete, i.e., good
Good thermal and insulating performance, this is not available for normal concrete.Usual density rating is in 300-1200kg/m3 range
Foamed concrete, for thermal coefficient between 0.08-0.3w/ (mK), thermal resistance is about 10-20 times of normal concrete.Using hair
Concrete is steeped as building masonry wall and roofing, and there is good energy-saving effect.3, sound-proof refractory performance is good, and foaming is mixed
Solidifying penus porous material, therefore it is also a kind of good acoustic material, in the sound insulation of the floor and highway of building
The material can be used as puigging in plate, top layer of underground structure etc..Foam concrete is inorganic material, will not be burnt, from
And there is good fire resistance, it is used on building, the fire protecting performance of building can be improved.
