COMPOSITE MATERIAL, PROCESS FOR MANUFACTURING SAME, AND USE

摘要

The invention concerns a composite from one or more first pre-shaped reinforcing materials which play a part in determining the final shaping and which comprise organic and/or inorganic material of a high tensile strength, and from a second material comprising an alkali metal silicate (waterglass) and a finely divided (disperse) mineral filler, the curing having been effected by drying at 80 to 120 DEG C or by drying at 80 to 120 DEG C and subsequent heat treatment (tempering) at 400 to 700 DEG C. The invention also provides the process for producing this composite and for its use as a fire-resistant building element which has a high tensile strength in flexure and any desired shape.
