PROCÉDÉ DE FABRICATION EN CONTINU D'UNE MOUSSE MINÉRALE À FAIBLE DENSITÉ
A method for the continuous production of a mineral foam of which the density in the dry state (d) is from 40 to 600 kg/m3, includes (i) mixing cement; a water reducing agent; 0.5 to 10%, % by weight with respect to the total weight of cement, of ultrafine particles having a liquid-solid contact angle comprised from 30° to 140°, and of which the D50 is from 10 to 600 nm; water, with a water/cement weight ratio from 0.3 to 2.5; (ii) adding to the mixture from 0.5 to 10% of a pore-forming agent, % by weight with respect to the weight of cement; (iii) applying the mixture obtained at step (ii) on a support; (iv) leaving the mixture to expand on the support.
