Description
Technical field
The present invention relates to technical field of concrete, especially a kind of foam concrete and preparation method thereof.
Background technology
Foam concrete is also known as foam cement, lightweight mixed mud etc., is that a kind of profit is useless, environmentally friendly, energy saving, cheap and have
Non-flame properties novel building energy-saving material.Lightweight concrete (foam concrete) is by way of chemically or physically according to application
It needs the gases such as air or nitrogen, carbon dioxide gas, oxygen being introduced into concrete mortar, be molded by reasonable maintenance, and shape
At containing a large amount of tiny sealed porositys, and the concrete product with suitable intensity.Lightweight concrete (foam concrete)
Making be typically foaming agent aqueous solution to be mechanically prepared into foam, then foam is added to containing siliceous material, calcareous
In the slurries of compositions such as material, water and various additives, through a kind of porous material made of mixing, moulding by casting, maintenance.
The production method of foam concrete has two kinds of damp sand slurry processes and dry sand slurry processes.Damp sand slurry processes are typically to be stirred in concrete
It mixes station and cement, sand etc. is stirred into mortar, be used in combination truck mixer vehicle to be transported to building site, then sand is added in separately made foam
Slurry, blender mix foam and mortar thoroughly, then by the foam concrete prepared injection pump truck conveying or scene directly construction.
Dry sand slurry processes are that transport or transmission system are delivered to construction site by each dry basis (cement, flyash etc.) by dissipating, and do group
Part with water mix at the construction field (site), mortar then is added in separately made foam, the two mix in homogenizer is subsequently used for
Site operation.
Since this foam concrete consistency is smaller, viscosity cannot overcome the surface spreading power of foam, in slurry not
With the foam of position, there is different degrees of increase at any time in diameter, to keep its part foam diameter bigger than normal, and steeps
Foam diameter differs, and adds bubble shakiness, declines at bubble rate ability；Finally influence into the quality of bubble.
Invention content
The technical problem to be solved by the present invention is to：Overcome deficiency in the prior art, a kind of high, coagulation at bubble ability is provided
The high foam concrete of native consistency, it is a further object to provide a kind of preparation methods of foam concrete.
