Abstract

Pond ash is the byproduct and is produce from coal plants. These plants release byproduct in major quantity which effects the environment. In this paper, an experimental work has been done on the conventional concrete with pond ash as replacement of fine aggregate. The grade of the concrete is M-40 and nine concrete mixes named as F1, F2, F3, G1, G2, G3, G4, G5 and G6 were prepared with different replacement ratios (10, 15 and 20 percent) of pond ash using alccofine 2.5 and 5 percent as replacement of cement. Each set of concrete mix comprised of 6 cubes, tested at the age of 7 and 28 days of curing period. it is concluded that optimum replacement of fine aggregate in M-40 is achieved at 15% pond ash using 5% alccofine. Therefore, the utilization of pond ash as partial replacement of fine aggregates will be feasible, economical and safe from environmental point of view and hence can be used as an alternative to fine aggregates.
