The invention relates to a thermo-insulating material with a cellular structure comprising, by weight relative to the total weight of the material: - 4 to 96% of a hydraulic binder characterized before contacting with water, in that it comprises at least one phase chosen from C3A, CA, C12A7, C11A7CaF2, C4A3 $ (yée lemite), C2A ( 1-x) Fx (with x belongs to] 0, 1]), hydraulic amorphous phases having a C / A molar ratio between 0.3 and 15 and such that the cumulative Al2O3 contents of these phases are between 3 and 70% by weight of the total hydraulic binder, - 4 to 96% of at least one load, said material exhibiting a porosity by volume of between 70% and 95%.n n n The invention also relates to the use of a mineral foam for manufacturing said heat-insulating material as well as the processes for manufacturing said mineral foam. |
