Generally, mortar is a uniform combination of fine aggregate and cement. In this study an innovative concepts adopts to synthesis a hybrid mortar with fly ash and quarry dust which are replacing the fine aggregate. The alternative materials are preferably waste products such as quarry dust and fly ash in order to moderate the cost of mortar. The main objective of this work is to study the compressive strength of mortar cubes by various combinations of fine aggregate replaced by fly ash, quarry dust at the age of 7,14,28 days. The results of mortar made with fine aggregate replaced by (50% QD- 50FA),(60% QD- 40%FA), and (70%QD- 30%FA) of quarry dust and fly ash were compared with conventional concrete. It is done the concrete grade of M30 and OPC 43 grade cement.
