    摘要： A cellular structure thermal insulation material includes by weight as compared to the material total weight: from 4 to 96% of a hydraulic binder, which prior to being contacted with water, includes at least one phase selected from C3A, CA, C12A7, C11A7CaF2, C4A3$ (Yee lemite), C2A(1-x)Fx (where x belongs to [0, 1]), hydraulic amorphous phases having a C/A molar ratio ranging from 0.3 to 15 and such that cumulated amounts of Al2O3 of these phases be ranging from 3 to 70% by weight of the hydraulic binder total weight, from 4 to 96% of at least one filler, the material having a pore volume ranging from 70% to 95%. The use of a mineral foam for making thermal insulation material as well as methods for making the mineral foam are also described.

    摘要： An aqueous suspension is provided including a mixture of at least one aqueous suspension of precipitated silica and of at least one latex, in which the aqueous suspension of precipitated silica has a solids content of between 10 and 40% by weight, has a viscosity lower than 4×10−2 Pa s at a shear of 50 s−1 and, after centrifuging at 7500 revolutions per minute for 30 minutes, produces a supernatant containing more than 50% of the weight of the silica initially in suspension. This suspension can be employed in compositions based on an inorganic binder and in concrete compositions.

    摘要： A process for spraying concrete or mortar, by a dry route or by a wet route, in order to produce on a surface a layer of concrete or of mortar. Just before or at the time of spraying, an aqueous suspension (A) of silica and of an aluminum compound chosen from aluminum sulphate, basic aluminum sulphates, alums and mixtures thereof is added to the concrete or mortar. The aqueous suspension (A) has a pH lower than 4, a solids content of between 10 and 50% by weight, and, after a period at rest of 48 hours, is in the form of a gel which is reversible under low shear. The aqueous suspension (A) is effective for increasing the thickness of the sprayed layer and reducing rebound of the concrete or mortar sprayed onto the surface.

    摘要： When decoding a set of symbols to be decoded, several data blocks representative of the set of symbols to be decoded are received by a decoding node of a communications network. The data blocks are encoded using an error correction code enabling a decoding by erasure. The decoding node performs the following steps: first selecting at least one of the data blocks, first determining first erasures, and checking whether the number of the first erasures is below a given threshold. In a case the check is positive, the decoding node performs first decoding by erasure of the set of symbols to be decoded. In a case the check is negative, the decoding node performs second selecting of at least one of the data blocks, second determining second erasures, and second decoding by erasure of the set of symbols to be decoded from the second erasures.
