FRACTURE AND STRENGTH STUDIES ON CONCRETE WITH
coarse aggregate Six types of coarse aggregates namely Granite Dolerite Quartzite Limestone Dolomitic limestone and River gravel were used in concrete making Three concrete mixes will be designed for a characteristic compressive strength of 30 50 and 70 MPa at 28day with a w c ratio of 0 5 0 35 and 0 3 respectively
