Among the many known Supplementary Cementitious Materials (SCMs), the useful ones for concrete are flyash blast furnace slag, silica fume, metakaolin and rice husk ash. Their use with cement has led to the development of binary and ternary blended cement concrete depending on whether cement replacement is carried out with a single SCM or a combination of two SCMs. Cement production lead to consuming significant amounts of natural resources, that has brought pressure to reduce cement consumption by the use of supplementary cementing materials. The aim of the present study is to evaluate the compressive strength performance of ternary concrete containing Industrial by-products like, Micro Silica and GGBFS as a partial replacement of the OPC. Compressive Strength of Ternary Blended Concrete at the age of 7, 28, 60, 90 days for various combinations of Micro Silica and GGBS mixes were investigated. Micro Silica of 0%, 5%, and 10% and 15% along with GGBFS was replaced by 20%, 30% 40% and 50% respectively. All the mixes were studied at water cement ratio of 0.35.
