A STUDY ON SUITABILITY OF POND ASH AND FLY ASH IN CONCRETE AS A REPLACEMENT TO FINE AGGREGATE AND CEMENT FOR SUSTAINABLE DEVELOPMENTR. Vijayan and T.R. Neelakantan
River sand is expensive due to the depletion of natural resources. Large scale depletion of these sources creates environmental problems In such a situation pond ash can be used as an alternative to the river sand. Enormous amount of production of cement increases the temperature of earth. So it is advisable to use Flyash as replacement material for cement.We have attempted to use Pond ash and flysh as a replacement material for fine aggregate and cement by replacing sand in various percentages. We have taken pond ash and flyash from four thermal power plants namely Neyveli, Mettur, Ennore, Tuticurin and carried out tests to find out the optimum percentage replacement of fine aggregate by pond ash and cement by flyash.
