| Popis: | Extensive research work for decades also in progress throughout the globe in concrete technology in finding alternative materials which can partially replace ordinary Portland cement (OPC) and which can also meet the requirements of strength and durability performance of industrial by products like Micro silica, ground granulated blast furnace slag, flyash, metakaolin, rice husk ash etc. now termed as complimentary cementitious materials (CCM) are quite promising. Subsequently these have led to the development of binary, ternary and quaternary blended concretes depending on the number of CCM and their combinations used as partial replacement materials. The Present experimental investigation is carried out in the optimization of a Ternary Blended Cementitious system based on Ordinary Portland Cement (OPC)/ GGBS / Micro Silica for the development of Ternary Blended Concrete. Compressive Strength of Ternary Blended Concrete at the ages of 7, 28, 60, 90 days for various combinations of Micro Silica and GGBS mixes were investigated. Micro Silica of 0%, 5%, and 10% and15% along with GGBS was replaced by 20%, 30% 40% and 50%. All the mixes were studied at water cement ratio of 0.45. |
