ABSTRACT:
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.
