Utilization of Waste Marble Dust and Granite Dust for Manufacture of Sustainable Concrete

The basic objective of this research was to identify alternative source of good quality aggregates. Marble and Granite are important materials used in construction industry. Marble dust is produced from processing plants during sawing and polishing of marble blocks and about 20-25% processed marble is turned into powered form. Granite dust is the stone waste generated from granite stone industries. Disposal of these wastes from the industries is one of the major environmental concerns worldwide. The present investigation was undertaken to study the effect of Marble dust and Granite dust on the mechanical properties of concrete. The main parameter investigated was the cube compressive strength. In this research, M-25 grade concrete mix was prepared using IS method of mix design. Cubic specimens of dimension (150 x 150 x 150) mm were casted for compressive strength test. Total of 24 cubes were casted, 6 specimens of nominal mix, 6 specimens with 20% marble inclusion, 6 specimens with 20% granite inclusion and 6 specimens with 10%-10% both marble and granite inclusion. Cubes were tested for 7 days and 28 days.
