BEHAVIOR OF THERMAL ASH AGGREGATE ON GEOPOLYMER CONCRETE BEAMS

To eliminate the natural stone as a part in geopolymer concrete, artificially made thermal ash aggregate was introduced as coarse aggregate. About 130% of the compressive strength was increased in full replacement of natural stone with thermal ash aggregate. With the increase in workability and strength of geopolymer concrete using artificial aggregate, it was decided to check its performance in geopolymer concrete beams. By varying the thermal ash aggregate in geopolymer beams, its load to deflection and moment rotation curvature at the time of external loading are observed, discussed and compared
