Polymer-aggregate systems: research on this new material was undertaken to formulate and develop unique properties for application as building construction materials. Sand, gravel, gypsum, clay and chopped glass fibers combinations were cast, using a polyester-styrene-methyl-methacrylate binder, and tested. All of the polymeraggregate systems tested had compressive, flexural, and tensile strengths in excess of those of fairly high strength conventional concrete. Specific values of strength ranged from two to nine times those of fairly high strength conventional concrete. The principal advantages of the materials include: good handling and workability for casting flexibility, rapid ambient temperature cures for fieId-erected structures, a range of desirable color and finish options for eliminating finishing or decorative operations, exceptional strength and durability with densities less than conventional concrete for relatively lightweight structural and decorative applications. Special applications of the materials developed are, variously: light-diffusing translucent panels, sculptural or color-oriented panels, tiles, fixtures, interior and exterior flooring and walls, structural components with strength-to-weight ratios. Other applications include most of those for which concrete is currently being used.
