EVALUATION OF SYNTHETIC AGGREGATE FROM LIGNITE FLY ASH

SEVERAL METHODS OF AGGLOMERATING AND BURNING FLY ASH PELLETS, INCLUDING ROTARY KILN AND SINTERING GRATE, WERE INVESTIGATED. THE AGGREGATES PRODUCED WERE EVALUATED IN TERMS OF THEIR TECHNICAL POTENTIAL FOR USE AS A STRUCTURAL QUALITY AGGREGATE. MAJOR CONCLUSIONS REACHED ARE THAT HIGH QUALITY, NONBLOATED, SYNTHETIC AGGREGATE CAN BE MADE FROM EITHER THE ROTARY KILN PROCESS OR THE SINTERING GRATE PROCESS; FLY ASH AGGREGATE PROPERTIES MEET OR EXCEED THE PROPERTIES OF THE COMMERCIALLY PRODUCED LIGHTWEIGHT AGGREGATE IN ALL RESPECTS EXCEPT UNIT WEIGHT; AND CONCRETE MADE FROM THE FLY ASH AGGREGATES INVESTIGATED SHOULD PROVIDE MORE THAN ADEQUATE STRENGTHS AND SUITABLE DURABILITY. FURTHERMORE, THESE CONCRETE STRENGTHS EXCEED THOSE MADE WITH THE COMMERCIAL LIGHTWEIGHT AGGREGATE.
