Abstract
The invention relates to a method for producing a packing structure, characterized in that it includes the following main steps: a) a step comprising the hydrothermal synthesis of the packing mass, performed using a mixture of quicklime and silica; and b) a step comprising the drying of the packing mass produced in step (a) at a temperature T2 of between 110° C. and 500° C., possibly with at least one intermediate stage performed at a temperature of between 111° C. and 350° C. over a period t2 selected such that the physisorbed water content of the packing mass is less than 0.5%.
