Abstract

As the manufacturing process of Portland cement increases the emission of Co2 in to the atmosphere also increases, so there is an urgent need in construction industry to find an alternative construction material. The main objective of this investigation is to compare a strength parameter and behavior of fresh and hardened concrete with conventional concrete and quaternary blended cement concrete in various percentages. The SCM's used are GGBS, MK, RHA in concrete not only reduces the carbon dioxide emission, but also impart significant improvement in workability and durability. The blend is quaternary type and the materials used are agricultural by products and industrial waste. The workability and strength characteristics of quaternary bend was found out by the replacement of 5%, 10%, 15% and 20% of GGBS, RHA and MK. Out of all pozzolonic material GGBS gives highest strength in Compression after 28 days. By replacing cement with and 10% MK, 5% RHA and 15% GGBS gives the compressive strength 50% more than the reference mix for 28 days respectively.
