Use of quality materials, lower water-binder ratio, larger ratio of coarse aggregate to fine aggregate, smaller size of coarse aggregate, fine aggregate of high fineness modulus, suitable cementitious materials and High Range Water Reducer (HRWR) with all materials to their optimum contents are found necessary for producing High Performance Concrete (HPC). Porosity and pore structure characterize the HPC materials in connection with mixture optimization. All are important, but the transition zone is particularly significant with respect to HPC. The aim of concrete mix design is to produce as economically as possible concrete of good workability while maintaining the specified strength, durability and fracture characteristics. This paper emphasizes the properties and dosages of various materials of HPC and comparison of different mix design methods.
