World foam concrete preparation of new technologies

2014-10-08 18:42:52

Foam concrete as a new building material, is widely used, it can be said the rapid technological advances, more advanced in Japan already has concrete preparation techniques.
Japan uses a protein substance to add the right amount of a cationic surfactant mixed blowing agent dubbed, using live cast molding process, the successful development of new technology-situ foam concrete.
The foams are made ​​with a total incorporation of 0.1% to 5% cationic surfactant in the protein and formulated, using the quaternary ammonium salt cationic surfactant. Prepared in three ways: one is to water, protein composition, the cationic mixed surfactant, the foamed foaming machine, and then injected into the cement slurry was stirred to prepare a foamed slurry, cast molding; kind is water, protein composition, the cationic surface active agent are mixed, the foaming by high speed mixer, and then injected into the cement slurry, the production of the foamed cement slurry; press the second one is a foamed, while adding a small amount of cement while stirring at high speed, Preparation of the foamed cement slurry, wherein the production method is preferably the former.

Above preparation method of production of in-situ concrete is not only lightweight, high strength, fire resistance, more compelling is the need autoclave curing, can cast molding, energy-saving effect is remarkable.
