METHOD FOR THE PRODUCTION OF A HYDRAULIC BINDER FOAM

摘要

A method for the production of a hydraulic binder foam which may subsequently be used to make a finished product such as a thermal insulation product, includes the steps of preparing a paste or a slurry from a hydraulic binder and a foaming agent; feeding the paste or the slurry to a foam generator and introducing compressed air into the foam generator to produce an aerated product; and pumping the aerated product and additional compressed air from the foam generator through a length of piping thus causing turbulence of the aerated product and the compressed air so as to produce a hydraulic binder foam exiting the length of piping. The hydraulic binder foam exiting the length of piping is air saturated and thus of a consistent density as a function of the liquid to hydraulic binder ratio rather than as a function of the method of production.
