Utilizing alternative material resources which are obtained as by products from various manufacturing industries are considered for research for better and reliable outcome so as to adapt these in future. This thesis, presents the optimization of partial replacement of coarse aggregate by oil palm shell which can act as light weight concrete in grade of M30 which are evaluated for its fresh and hardened properties say compressive strength, split tensile strength, flexural strength, fresh and 28-day air dried density where coarse aggregate will be replaced with oil palm shell in five different proportions (i.e., 10%, 20%, 30%, 40% and 50%) as per IS 10262 -2019 and IS 456 - 2000.
