Concrete Mix Design as Per IS Method of Mix Design

Concrete mix design may be defines as the art of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength& durability as economically as possible. Considering objectives of mix design desired workability in the plastic stage, desired minimum strength in the hardened stage, desired durability in the given environment conditions& basic considerations like cost, specification, workability is to be studied while designing mix design. Grade of concrete& its Characteristics compressive strength of 150 mm cube at 28 days, N/mm2 is very important criteria to be considered. Factors affecting choice of mix design is being studied for better mix design.
