Durability study of Conventional Alccofine Concrete with utilization of Pond ash as the Partial Replacement of Fine Aggregate

The Thermal power plants discharge waste materials as by-products which altogether are threat to environment. Disposal of them is a huge problem now-a-days. It consumes large part of land and also has many environmental hazards. In this study, an experimental work has been done on the M-40 grade of concrete with pond ash as a replacement of fine aggregate using different percentages of Alccofine. Nine concrete mixes named as C1, C2, C3, G1, G2, G3, G4, G5 & G6 were prepared with different replacement ratios (10, 12.5 and 15 percent) of pond ash and adding 2.5 and 5 percent Alccofine was used instead of cement. It is concluded that optimum replacement of fine aggregate in M-40 grade of concrete is achieved at 12.5% pond ash using 5% Alccofine after 28 days of curing. This study will be helpful to make reasonable and inexpensive concrete using of pond ash.
