Fly ash is abundantly available in India. IS 3812 Part I & II regulate its usage in cement and concrete. It is well known fact that fineness of fly ash goes on increasing from boiler end to chimney, however the output goes on reducing. Past research normally indicate usage of finer (Hopper no. 4 & 5) fly ash in cement and concrete. Japan has upgraded its standards and specifications to accommodate all grades of fly ash available. The present research by the authors on all grades of fly ash samples through compressive strength development indicate all grades of fly ash can be used in concrete with a precaution that their performance should be investigated before use. Through graphical representations of test results presented in the paper, it is justified that coarser fly ash can very well be used in concrete making as per strength requirements.
