Patent ID: 8628708

Claim:
A process for producing a container packing structure comprising a crystalline phase containing 55 to 97% by weight of xonotlite crystallites and 3 to 45% by weight of tobermorite crystallites, less than 15% by weight of intermediates of formula: Ca x Si y O z,w H20 with 1 x 16, 1 y 24, 4 z 60 and 1 w 18, and having less than 5% by weight of CaCO3 and less than 5% by weight of SiO2, said packing structure being homogeneous, characterized in that it comprises the following main steps: a) a hydrothermal synthesis step for synthesizing the packing mass, carried out by mixing quicklime with silica; and b) a drying step, for drying the packing mass resulting from step a) with at least one intermediate temperature hold T 2 ′ carried out at a temperature between 111° C. and 500° C. prior to a drying hold at a temperature T 2 between 110° C. and 500° C. for a time t 2 chosen such that the content of physisorbed water of the packing mass is less than 0.5%, to produce the container packing structure comprising a crystalline phase containing 55 to 97% by weight of xonotlite crystallites and 3 to 45% by weight of tobermorite crystallites, less than 15% by weight of intermediates of formula: Ca x Si y O z,w H20 with 1 x 16, 1 y 24, 4 z 60 and 1 w 18, and having less than 5% by weight of CaCO3 and less than 5% by weight of SiO2, said packing structure being homogeneous.
