Abstract

This paper presents the experimental and analytical studies of the strength and ductility of high calcium fly ash
based geopolymer concrete beam when subjected to ambient curing. The investigations were carried out on geopolymer
concrete beams of various grades and sodium hydroxide molarity of 12 M. The beams were designed as under reinforced
with tensile reinforcement ratios 1.25% and 1.80 %. The beams were tested under two point static loading. Performance
aspects such as load deflection behavior, ductility index, young’s modulus and energy absorption capacity were studied. The
test results showed that the geopolymer concrete beam exhibits better performance.
