Natural river sand is one of the key ingredient in concrete, now a days it is expensive due to over population and increasing infrastructure projects and also large scale of depletion of natural resources create environmental issues. To overcome these problems there is a need of alternate and economical resource in construction industry. Quarry dust is a waste obtained during quarrying process, it is an effective filler material. Metallic dust is a by-product of carbon steel which is obtained from industry. This paper analysis the use of quarry dust and metallic dust in concrete production. Design mix of M20 grade concrete with partial replacement of fine aggregate with 0%, 20%, 30%, 40%and 50% of quarry dust and 2% of metallic dust with all the fraction of quarry dust is used to increase its strength of concrete. Various tests like specific gravity, fineness, consistency, setting time, bulking of sand, water absorption, impact value, slump value, compaction factor and compressive strength of concrete is carried out. The result proves that there is an increase in compressive strength of concrete.
