The present invention relates to a container packing structure, characterized in that it comprises a crystalline phase containing 55 to 97% by weight of xonotlite crystallites and 3 to 45% by weight of tobermorite crystallites. It also relates to a method for fabricating such a packing structure, and the container containing same, and its use for storing fluids such as gases.

1. A method for fabricating a packing structure comprising a crystalline phase containing from 55 to 97% by weight of xonotlite crystallites, from 3 to 45% by weight of tobermorite crystallites, and one or more intermediate phases based on Ca, Si, O and H and of the formula CaxSiyOz.wH2O in a propor
1. A method for fabricating a packing structure comprising a crystalline phase containing from 55 to 97% by weight of xonotlite crystallites, from 3 to 45% by weight of tobermorite crystallites, and one or more intermediate phases based on Ca, Si, O and H and of the formula CaxSiyOz.wH2O in a proportion of up to 15% by weight, wherein the method comprises the successive steps consisting of: a) calcining limestone blocks at a temperature of at least 850° C. for at least one hour, such that at least 90% by weight of the said blocks have dimensions of 1 to 15 mm, the said limestone having a purity of at least 92% by weight and an open porosity of between 0 and 25%, to obtain quicklime particles,b) mixing the said particles, in aqueous medium with silica and optionally with other compounds, to obtain a slurry,c) subjecting the said slurry to hydrothermal synthesis at a temperature of between 170 and 300° C., to obtain a ceramic mass, andd) drying the said ceramic mass at a temperature of 300 to 450° C. for a period of 40 to 200 hours. 2. The method of claim 1, wherein at least 90% by weight of the said limestone blocks have a size of 1 to 12 mm. 3. The method of claim 1, wherein the said limestone has a purity of at least 95% by weight, or even at least 97% by weight. 4. The method of claim 2, wherein the said limestone has an open porosity of between 0 and 25%, determined by mercury porosimetry. 5. The method of claim 2, wherein the hydrothermal synthesis is carried out at a temperature of between 180 and 250° C. 6. A container that includes a container packing structure, wherein said container packing structure comprises a crystalline phase containing from 55 to 97% by weight of xonotlite crystallites, from 3 to 45% by weight of tobermorite crystallites, and one or more intermediate phases based on Ca, Si, O and H and of the formula CaxSiyOz.wH2O in a proportion of up to 15% by weight, said packing structure comprising at least 90% by weight of crystalline phase, and wherein said container is in the form of a cylinder suitable for containing and delivering a fluid, wherein said container contains acetylene dissolved in a solvent. 7. The container of claim 6, wherein the solvent is selected from DMF or acetone.
