The use of multi-component waste products provides anopportunity to produce a roofing material with an excellent balance ofcost and properties. Simulated slate tiles comprised of fly ash, otherreinforcing filler, and thermoset hybrid resin have been modelled. Basedon initial market reactions to preliminary cost, physical propertiesdata, and appearance, this application appears promising. Ecomat hasdemonstrated that mixing techniques, when used with certain by-productcharacteristics produce solids that are 90 weight percent waste products.Physical properties can be significantly changed by altering the leveland type of by product, chemical component, or basic ratio of onethermoset polymer to the second which make up the hybrid.
