ABSTRACT:
The method for recycling construction and demolition fines involves using mixed fines from construction and demolition debris that would otherwise be disposed of at landfills as an ingredient in cement or concrete. The mixed fines contain a plurality of materials selected from the group consisting of asphalt, plastics, ceramics, fiberglass and batt insulation, soil, dust, drywall, wood, plaster, paper, cardboard, dirt. The fines may also contain particles of recyclable materials, such as concrete, bricks, mortar, metals, glass, and the like. The fines may range in size from microns up to 6 inches in at least one direction. The recycler may incorporate the fines into a concrete mix for bulk sale to commercial enterprises, or may himself form precast, lightweight concrete products, such as decorative columns, pedestals and table bases, trim moldings and cornices, door surrounds, etc.
