Abstract: Concrete is an important and commonly used man made construction material, which can be considered to have better strength and durability characteristics. Nowadays, ternary blended concrete is achieving popularity by overcoming the disadvantages of binary blended concrete. The present work deals with study of fresh properties, strength and durability of ternary blended concrete with Ground Granulated Blast Furnace Slag (GGBS) and Rice Husk Ash (RHA). Concrete mix is designed for strength of 40MPa. The study is limited to ternary blended concrete with 50% replacement of cement with GGBS and remaining 50% of cement is replaced with 5%, 10% and 15% RHA in different mixes. The chloride penetration resistance of the concrete is assessed by rapid chloride permeability test. The observations were critically analysed and the different attributes of the various mixes were correlated with the RHA content in the mix.
