BIS method of mix design is applicable for a maximum compressive strength of 40Mpa hence it cannot be applied directly for HPC. Concrete of strengths 60, 80 and 100 MPa were developed by usingwell pronounced for Mix A having 100% OPC is greater. Surekha T; Dr. Chandrasekhar A2 was investigating the strength properties of GGBS & MS along with Polyvinyl Chloride (PVC) dust at the various replacement levels in M40 grade of concrete.
