C14 FATTY ALCOHOL EMULSE AGENT, PROCESS FOR PREPARING THE EMULSE AGENT, USE OF THE MIXED EMULSE AGENT WITH HYDRAULIC BINDER, PROCESS FOR PREPARING EXPANDED OR CELLULAR CONSTRUCTION ELEMENT, AND EXPANDED OR CELLULAR CONSTRUCTION ELEMENT SO OBTAINED

摘要

An emulsifier comprises a C14 fatty alcohol, preferably a mixture of C10-C16 fatty alcohols or better still a mixture of fatty alcohols with a predominantly C12-C14 content. It has been discovered that this type of emulsifier containing a C14 fatty alcohol induces carbonation of the hydraulic binder such as cement, thereby improving the mechanical properties of the finished product. In addition, this emulsifier is a powerful foaming agent, and has a longer shelf life and improved stability to thermal shocks.
