A silicocalcareous mass obtained from an aqueous paste with a base of natural silica and quicklime. The mass is at least doubly stabilized by two mineral suspending agents, and reinforced by a fibrous reinforcing agent. The suspending agent comprises cellulose fibers which may be partially chemically delignified, partially mechanically delignified, or delignified by a combination of chemical and mechanical processes, introduced in an amount of from about 3 to about 30% by weight of the solids. The porous silicocalcareous masses are used for lining containers for gas storage, particularly for containers for storing acetylene gas.

High-porosity silicocalcareous mass for storing of gas, and production

A high porosity silicocalcareous mass is obtained by using in at least partial replacement of the usual silica, amorphous ultrafine synthetic silica particles having a specific surface between 150 and 300 m.sup.2 per gram, and a high absorption capacity, and optionally adding nonreactive synthetic fiber of either inorganic or organic origin to the mixture containing the particles. The high-porosity silicocalcareous mass can be used as a lining material for containers, which are intended for storing liquified or dissolved gases and also as an insulation material, such as sound insulation in building construction.

Preparation and use of high porosity silicocalcareous mass

A silicocalcareous mass with high porosity is obtained by using, in at least partial replacement of the usual silica, ultrafine synthetic silica with a large specific surface of 200 to 500 m.sup.2 per gram to a paste of lime and silica, and possibly adding nonreactive synthetic fibers of organic or inorganic origin. The silicocalcareous mass with high porosity can be used in the field of lining materials for containers intended to store dissolved gases and in the field of insulation materials.
