Cement industry is one of the major sources of environmental pollution as it consumes a lot of energy in the production and releases huge quantities of CO2. Added to this is the growing environmental problem due to excess production of solid waste materials like Fly Ash (FA), Silica Fume (SF) which has tempted many researchers to try these materials as concrete ingredients. Therefore, this paper proposes to investigate the strength characteristics of Ternary Blended Concrete (TBC) for M40 grade and to arrive at an optimum TBC mix. All the mechanical properties are observed to increase with the introduction of pozzolans in concrete with different percentages. 30% of the cement is replaced with various combinations of FA and SF and the strength is found to be optimum for 20% FA and 10% SF.
