  • Patent number: 4249991
    Abstract: A material of the board type for various thermal shielding applications preferably contains 10 to 50% by weight of a mineral substance based on silica or silicates in fibrous form prepared from the fused substance, 10 to 70% by weight of clay, if necessary 10 to 60% by weight of a mineral having a needle-like crystal structure, and a small proportion of an organic binder for maintaining the mineral constituents in a coherent structure at least during fabrication, conversion and utilization of the end product. The total quantity of organic substances does not exceed 8% by weight of dry substances. The material has high temperature strength by virtue of the combination of an organic binder with a mineral binder and also has good dimensional stability.

  • Patent number: 4246036
    Abstract: The colored composite material is manufactured from materials based on a hydraulic binder and dispersed reinforcing elements, for example fibrous. To obtain a colored material, a composition comprising a baked clay such as chamotte is used generally by replacing at least in part the silica in products preferably hardened under steam pressure. The materials obtained are useful particularly as covering elements for frontages in the building industry.
