ABSTRACT:
A polymer-based blend which may be cured to form a non-cementious concrete-like material. The polymer-based blend includes 90 to 100 parts by weight low viscosity epoxy resin, 1 to 10 parts by weight of an aliphatic glycidyl ether epoxy diluent, 40 to 50 parts by weight polyoxy-propyleneamine curing agent, 30 to 100 parts by weight intumescent powder, 90 to 110 parts by weight hollow ceramic microspheres having a density of between 0.30 and 0.60 grams per cubic centimeter and 0.01 to 0.10 part by weight air release agent. The hollow ceramic microspheres are dispersed uniformly throughout the polymer-based blend to provide a non-cementious material which, upon curing, becomes a concrete-like material. The non-cementious concrete-like material is well-suited for use as a substitute for concrete and may be used alone or in combination with reinforcing materials.
