Abstract: Fly ash is investigated for its use as a replacement for cement and fine aggregate in cement mortar. This paper presents the results of the cement mortar of mix proportion 1:3, 1:4.5 and 1:6 cement mortar in which cement is partially replaced with Class-F fly ash as 0%, 10%, 20%, 25% and 30% by weight of cement. Richer the mix, higher the compressive strength has been obtained even with partial replacement of fly ash with cement. Test results indicate the significant improvement in the strength properties of mortar with fly ash as partial replacement with fine aggregate and with the cement in the cement mortar 1:6. It can be effectively used in masonry with the compressive strength of the brick unit ranges between 3-20 N/mm2.
