Abstract: Concrete mix design involves the process of selecting ingredients with appropriate proportions. Creates the required strength and durability of the concrete structure. Material having different properties. Not easy to create a great mix of concrete. It is Imperative all ingredients be tested determine their physical properties then prepare the mix as per guidelines. But guidelines available for fresh raw or the natural material used in the mix design. Various steps include in mix design for this paper mainly focus on Target strength of concrete (Fck) Value variation. In case of recycled concrete material used in the mixed design. For the study casting the M25 grade. Recycled aggregate used up to 30 % by weight. Compare the statistical analysis variations used for mix design.

Keywords: Target Strength of Concrete, (Fck), Concrete mix Design
