Cementitious blends in which proportion of ordinary portland cement was replaced with the mineral admixtures. Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. Here is the standard chart table showing various grades of concrete mix design along with their respective ratios of cement, sand and aggregates required. The aim of this study is to investigate the characteristics exhibited by three different grades of concrete using mix design approach. This standard practice describes methods for selecting proportions for hydraulic cement concrete made with and without other cementitious materials and chemical admixtures.
