The study of effects of quarry dust on the strength of non-traffic paver block

Quarry dust is generated as a waste during the process of cutting and crushing. Crushing industry produces large amount of quarry dust which causes environmental problems. To reduce disposal and pollution problems the innovative use of quarry dust in concrete by replacing fine aggregate with this material is another alternative of the traditional concrete. The aim of this research is to replace sand by quarry dust accordingly in range of 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70% 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 sand via 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70% of quarry dust. Ultimately it was observed that the strength increases on replacing sand in concrete due to filler effect of quarry dust.
