Abstract : The paper deals with enhanced durability of concrete by the use of either blended cements i.e. Portland pozzolana cement or Portland slag cement or by the use of fly ash, blast furnace slag and silica fume in concrete construction. The processes of combating the alkali – aggregate reaction in hydro-electric projects by the use of fly ash or ggbs in conjunction with low alkali ordinary Portland cement, has been described. The benefits of using fly ash or ggbs in mass concrete resulting in limited rise of temperature in concrete have been demonstrated. The use of silica fume in concrete for abrasion resistance in spillways of concrete dams and in concrete pavements has been highlighted.
