Excess demand of natural resources on account of expeditious urbanization and the scrapping problem of agricultural waste have paved the way for research in usage of organic waste in the construction industry. Scores of organic waste materials have found their usage in concrete as substitute alternatives for cement, fine aggregate, coarse aggregate and reinforcing materials. This paper highlights and examines some of the organic waste material used as partial replacement of fine aggregate in concrete which is being defined and termed as organic waste concrete in present context. The paper aims at evaluating the strength characteristics of organic waste concrete by using different organic wastes and thus understanding the feasibility of using each organic waste. Distinct properties of fresh and hardened concrete, their reliability when admixed with organic wastes are examined. It has been observed that the organic waste concrete containing groundnut shell, rice husk ash, saw dust ash demonstrated more desirable workability than their other substitutes did. Organic waste concrete containing bagasse ash, sawdust ash attained their required strength by 20% of replacement as fine aggregate which were maximum among all organic waste type concrete. Accurate comparison was predicted among compressive strength, flexural strength and tensile strength of organic waste concrete. Introduction of bagasse ash as fine aggregate in concrete improved the resilience to chloride tapping. After the careful investigation, it is of substantial conclusion that additional exploration and testing is justified on all fine aggregates substituting organic waste, which would give further certainty on their exploitation in concrete.
