A process for the production of a mineral foam includes (i) separately preparing a slurry of cement and an aqueous foam, wherein the cement slurry includes water and Portland cement; (ii) contacting the slurry of cement with the aqueous foam to obtain a slurry of foamed cement; (iii) adding an aluminum salt source before or during step (ii); and (iv) casting the slurry of foamed cement and leave it to set.

A molded three-dimensional insulator that is suitable for use in an end cone region of a pollution control device and a method of making the insulator are described. The insulator includes ceramic fibers that have a bulk shrinkage no greater than 10 weight percent. The ceramic fibers can contain alumina and silica and can be microcrystalline, crystalline, or a combination thereof.

A method of forming a multi-use dry pavement from oily waste derived from hydrocarbons has the steps of combining the oily waste with calcium oxide so at as to suspend and homogenize the wastes, adding hydrogen peroxide and water to the oily mixture, and adding ammonium sulfate and water to the mixture. The hydrogen peroxide is mixed with equal amounts of water. The ammonium sulfate is mixed with an equal amount of water. The homogenization process continues until the mixed material forms a granulate. The granulate can be compacted and then used as a pavement.
