The infrastructure is developing day by day leads to increase in demand of concrete. Construction activity is readily dependent on concrete directly or indirectly., which significantly increase the demand of natural resources like sand (which is limited in nature) and using it significantly increase the impact on environment which result in erosion of river bed, lowering of water table etc. So, there is need to find the alternative for natural sand. Stone dust which is a waste produced in crusher while making aggregate, which can be used as an alternative of natural sand Stone dust has a similar specific gravity so it can be used. 24 Cubes of each grade has been casted and M20, M25, M30 grades are been casted and testes are being performed on them. NDT and DT tests are performed in them i.e. Compression testing using CTM (Compression testing machine) and in NDT Rebound hammer and ultrasonic pulse velocity tests are performed. Each cube is tested on 7days and 28 days and compression strength are found using all 3 tests and comparison is done and variation is found Between Compressive strength found using CTM and rebound hammer also variation is found between Compressive strength found using CTM and ultrasonic pulse velocity machine.IN CTM and Ultrasonic pulse velocity machine 3 readings are taken and then average is taken whereas in rebound hammer test 12 readings are taken from which the lowest and the highest is discarded and average is taken of 10 reading and rebound number is taken and using his rebound number compressive strength is found using the chart.
