Owning to acute shortage of natural sand in many areas and keeping environmental and cost factors into consideration an alternative for the same is pondered. In view of above discussion, an attempt is made to replace the cement and coarse aggregate in concrete of M50 grade with fly ash and ceramic waste to study the workability and compressive strength at 7,14 and 28 days curing periods. According to the results of the experiment, it is concluded that with increase in replacement of fly ash, the maximum compressive strength was obtained in M2 mix at 28 days which was 6.93% more than M0. In final mixes maximum compressive strength was achieved in M2C1 which was 13.61% more than M0 mix. Also the unit weight of the specimen decreased by 8% for M2C1therefore it can be used for lightweight concrete. Keywords- Natural Sand, Fine aggregates, Fly Ash, Ceramic Waste, Coarse aggregates I. INTRODUCTION Concrete is a paste of cement, water and aggregates and in some cases rocks. Water and cement mixture coats the surface of the fine aggregates and the coarse aggregates. The paste gets starts gaining strength and gets hardens to form the rock- like mass known as concrete through a process called hydration. Fly ash remains, which is additionally termed as "pulverized fuel ash", is one of the waste buildup produced by coal ignition, and is made out of the fine particles that are driven out of the boiler alongside flue gasses. Ash that settles down the base of the boiler is termed bottom ash. In the creation of Portland cement concrete fly ash is utilized as a secondary cementitious material (SCM). A secondary cementitious material, utilized as a part of conjunction alongside portland cement, adds to the properties of the solidified concrete through hydraulic or pozzolanic action or both.
