✦ Synopsis

The effect of replacing 30 % of portland cement by Spanish fly ash (class F according to ASTM C-618) and their sized fractions obtained using sieves on compressive and flexural strength of mortars was investigated. The study reveals an enhancement of compressive strength when fineness of fly ash fraction increases, particles with diameter less than 10 lam being crucial.
