The experimental studies on mortar containing flyash as a partial replacement of sand by weight as well as by volume were carried out to quantify its utilization. Both the types of pond and bottom flyash in various ratios were used in preparing cement mortar and their strengths in compression and tension were tested. Out of the various proportions the mortar mix 1:2.5:2.5 (cement: coarse sand: pond flyash) designed by method of volume is found satisfactory as for as the strength is concerned. The maximum utilization of flyash almost 75% and cost saving about 58% were ascertained with the plain mortar of ratio 1:5 (cement : sand). The utilization of flyash in mortar designed by weight provides 50% to 60% financial saving while 9% to 16% by method of volume. However, the flyash mortar mix 1:1:5 (cement:flyash:sand) by weight consumes about 20% less quantity of cement and overall consumption of flyash is also less.
