Abstract

A composition for forming a waterproof, high strength, hard material having good insulation properties, comprising a mixture of crushed pumice and type S mortar, and preferably refractory additives or fillers, which forms the hard material upon the addition of water and after allowing the mixture to cure. The material has superior insulation properties to conventional compositions formed using portland cement instead of type S mortar.
