Description
Technical field
The invention discloses a kind of light foam concrete and preparation method thereof, belong to building material technical field.
Background technology
Foam concrete is that foaming agent is mechanically fully foamed by the foamed system of foaming machine, and by foam with
Cement mortar uniformly mixes.Then cast-in-place construction or mould molding are carried out by the pumping system of foaming machine, through natural curing institute shape
Into a kind of novel light insulation material containing a large amount of sealed porositys.
The density of foam concrete is generally in 400~1600kg/m3, there is heat-insulated, sound insulation, lightweight, damping, energy-absorbing, suction
Sound, the pumpable multifrequency nature such as cast-in-place, as the study hotspot in building energy conservation emission reduction field, it is widely used in floor heating thermal insulation
Layer, roof heat insulation layer, wall self-insulation, stemming operation etc..
Foam concrete has the characteristics of small bulk density, insulation, is given birth in building field and functional form building product
Production etc. application is more and more extensive.The preparation method of foam concrete mainly includes following two at present：One kind is prefabricated bubble
Foam mixing method, i.e., foam is first prepared, then the foam prepared is mixed with cement mortar；Another kind is mixing method, i.e., mixed
The mix and foaming for coagulating soil are carried out simultaneously.Generally, the foam concrete prepared using preformed foam mixing method is had
Good mobile performance, can carry out long distance pumping, and the foam concrete prepared using mixing method then it is general not
Pumping and cast in situs can be used for.The intensity of foam concrete produces the increase of porosity and reduced with foam is introduced, and draws
It is more to enter foam, porosity is bigger, and unit weight is smaller, and its intensity fall is bigger, the system especially in ultralight foam concrete
During standby, due to low strength, therefore, do not require nothing more than used by binder materials tool very strict to the performance requirement of binder materials
There are higher early strength, faster setting time, also to possess the features such as early strength development is very fast, later strength is higher.
Also be present the problem of mechanical property is relatively low, and compressive property is bad in current light foam concrete, therefore, research and develop with common
Cement is major gelled material, economic durable, excellent performance novel light foam concrete is imperative.
