USE OF ENERGY-EFFICIENT SINTERED COAL REFUSE IN LIGHTWEIGHT AGGREGATE

The development and evaluation of a synthetic lightweight aggregate that has particular application to the building and transportation construction industries are described. Bituminous coal refuse, a waste product obtained from five coal-preparaton plants in Kentucky, was successfully sintered on a pilot-sized traveling grate to produce lightweight construction aggregate. An improved sintering-grate process was used. A means is thus provided for using a waste product while gaining an economic advantage during processing from the inherent fuel value of the refuse. A thorough laboratory investigation of the aggregate as a material for use in bituminous concrete mixes and structural lightweight portland cement concrete indicated that a satisfactory aggregate for these construction materials was produced. Using lightweight aggregate from sintered coal-mine refuse in concrete construction offers significant technical and economic incentives from the standpoints of reduced weight and the greatly reduced thermal conductivity of the products formed.
