The invention relates to a heat-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 being in contact with water, in that it comprises at least one phase selected from C3A, CA, C12A7, C11A7CaF2, C4A3 (lemite), C2A (1-x) Fx (where x is at 0, 1]), amorphous hydraulic phases having a molar ratio C / A between 0.3 and 15 and such that the cumulative Al 2 O 3 contents of these phases are between 3 and 70% by weight of the total hydraulic binder, 4 to 96% of at least one filler, said material having a coefficient of thermal conductivity at 20 ° C, equal to or less than 0.20 W / m. The invention also relates to the use of a mineral foam for producing said thermo-insulating material as well as the processes for manufacturing said mineral foam. |
