Optimum Replacement Level of Fine Aggregate with Stone Dust in Concrete with Reference to its Compressive Strength

Naturally occurring aggregates such as coarse aggregate and fine aggregate approved to Indian criteria is becoming scanter and expensive due to its non-availability in time because of commandment of land, illegitimate scouring by sand faction and ease of use to the river cradle during inclement season. This study was investigated to estimate the effect of fractional spare of natural sand with stone dust in concrete. Investigational plan was directed using 0, 20, 30, 40, 50 and 60% partial replacement of fine aggregate with stone dust taken for concrete of M25 grade with 0.48 water cement ratio. Set of cubes and beams were cast for compressive strength and concrete samples were verified after 7 and 28 d damp preserving. From the findings it was noted that 40% addition of fine aggregate with stone dust is adjustable.
