Abstract

The characteristic equations of the stress-strain curve for fly ash concrete (ordinary grade – M30Grade) are used to study the M-Ø characteristics of beam sections. The theoretical procedure has been validated by conducting an experimental investigation on under reinforced fly ash concrete beams. The correlation between experimental and analytical values of moments and curvatures arrived at based on the above procedure is found to be good. The cement was replaced by10, 20, 30 and 40% fly ash obtained from near by thermal power station.
