ABSTRACT
The construction industry has large potential to use the waste material. One of the best ways to
utilize the thermal power generated waste pond ash is to use it as a partial replacement for fine
aggregate in concrete. The study has been carried out for two grades of concrete viz., M20 and
M25 with replacement of pond ash as fine aggregate up to 40%. The strength characteristics
such as compressive strength, splitting tensile strength, flexural strength and modulus of
elasticity are investigated with various replacement ratios of pond ash and the results are
presented in this paper. Standard size of 150 ×150 ×150mmcubes, 100 ×100×500mmprisms,
150 × 300mm cylinders were cast for testing. In this investigation a total of 54 cubes, 54 prisms
and 108 cylinders were cast for testing. Test results after 28 days of curing were analyzed
and the comparisons for various replacement ratios are presented. The results obtained thus
encouraging a partial replacement of fine aggregate with pond ash up to 30%.
