METHOD OF PRODUCTION OF A MINERAL FOAM OBTAINED FROM A FOAMING SLURRY OF HIGH YIELD STRESS

METHOD OF PRODUCTION OF A MINERAL FOAM OBTAINED FROM A FOAMING SLURRY OF HIGH YIELD STRESS

The invention relates to a method for the continuous production of a low density mineral foam comprising the following steps: (i) preparing a cement slurry comprising: - cement; - ultrafine particles of which the D50 is comprised from 10 to 600 nm; - a water reducing agent; - a manganese salt; and -...

Zusammenfassung:The invention relates to a method for the continuous production of a low density mineral foam comprising the following steps: (i) preparing a cement slurry comprising: - cement; - ultrafine particles of which the D50 is comprised from 10 to 600 nm; - a water reducing agent; - a manganese salt; and - water; (ii) adding to the cement slurry obtained after step (i) a gas-forming liquid comprising: - a gas-forming agent; and - a viscosity-modifying agent which is a polymer chosen among anionic bio-based polymer, amphiphilic bio-based polymer, alkali swellable acrylic polymer and mixture thereof; to obtain a foaming slurry; (iii) applying the foaming slurry obtained at step (ii) on a support; (iv) leaving the foaming slurry to expand on the support.
