ABSTRACT 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. Keywords: geopolymer concrete, thermal ash aggregate, RCC geopolymer concrete beams.

INTRODUCTION Destroy in nature happens to get the aggregate for concrete [1]. Demolition of natural rocks can be avoided by introducing suitable alternative in concrete [2]. Thermal ash aggregate can be used as an alternative for natural stone as coarse aggregate in concrete [3]. Strength in concrete is determined by coarse aggregate [4]. Thermal ash aggregate gives good crushing value, good packing, etc. similar to hard natural stone. The physical properties of thermal ash aggregate perform better than the natural coarse aggregate [5]. Geo polymer concrete with thermal ash aggregate as coarse aggregate improves the workability and strength. Full replacement of natural aggregate in geopolymer concrete can be done with thermal ash aggregate [6]. The uniform size, less moisture content, good crushing
