Effect of Fly Ash on Recycled Aggregate Concrete

Fly ash was replaced by cement in % of 0%, 10%, 20%, 30% and 40%. Again natural aggregates were replaced by recycled coarse aggregates (RCA) in % of 0%, 10%, 20%, 30% 50% and 100%. Thus total thirty different trial mixes were prepared and the effects of RCA with fly ash, on fresh and hardended properties have been determined.
