The components are mixed until a tough plastic consistency is reached, this being effected by compacting and shear forces applied at room or raised temp., and optional hydrothermal storage. After this is added graded perlite or vermiculite. After further mixing the material is then formed, optionally foamed, autoclave hardened sawn up and dried. A kneading mixt. action is pref. used carried out pref. in several stages each time after one or several of the constituents have been added. The resultant material has superior uniform props. and structure. Used for sound, heat and radiation insulation.
