A composition that when cured possesses high temperature, chemical and abrasion resistance, and which can be formed into shapes, used as binder for aggregate fibers, sand or the like, or used to repair hard surfaces. The composition has a first part that is a slurry of an alkali metal silicate solution, such as lithium silicate, sodium silicate or potassium silicate, alone or in combination, combined with a non-reactive alkali metal, such as a silica flour or powder. The second part of the composition is a mixture of sodium silicofluoride, silica fume and sodium borate. A small amount of boric acid may be added to the second part to slow the curing reaction.
