Studies of Effects of Marble Powder on The Various Strength Parameters of Concrete

Marble dust is generated as a waste during the process of cutting and polishing. Marble industry produces large amount of marble powder which causes environmental problems. Cement being the costliest material of concrete, there is an urgent need to replace cement in concrete. Hence, to reduce disposal and pollution problems the innovative use of marble powder in concrete by replacing cement and fine aggregate with this material is another alternative of the traditional concrete. The aim of this research is to replace cement and sand by marble waste accordingly in range of 0%, 5%, 10%, 15%, 20% for M30 grade concrete. This research is concerned with the experimental investigations on workability and strengths of concrete and optimum percentage of partial replacement of cement and sand via 0%, 5%, 10%, 15%, 20% of marble powder. Three test mixes were prepared to test the suitability of marble dust in concrete. Mix-I contains 0%, 5%, 10%, 15% and 20% replacement of cement with marble dust in M30 grade of concrete. Mix-II has 0%, 5%, 10%, 15% and 20% addition of marble dust in traditional mix of M30 grade of concrete. Mix-III has 0%, 5%, 10%, 15% and 20% of marble dust as replacement of sand in M30 concrete grade. Ultimately it was observed that strength decreases on replacing cement in concrete, while strength increases on replacing sand in concrete due to filler effect of marble powder.
