FLEXURAL BEHAVIOUR OF REINFORCED CONCRETE BEAM WITH PARTIAL REPLACEMENT OF COARSE AGGREGATE WITH COCONUT SHELL

civil engineering

The rapid development in construction industry increasing demand for new innovative material as a part of construction industry. Coconut is grown in more than 93 countries. India is the third largest, having cultivation on an area about 1.78 million hectors. The properties of coconut shell aggregate concrete are examined and the use of coconut shell aggregate in construction is tested. Experimental studies are conducted on the flexural effect of coconut shell used in proportions of 5%, 10%, 15%, 20%, 25%, to replace coarse aggregate in conventional concrete M20 grade. This study will therefore focus on reinforced concrete beams with partial replacement of coarse aggregate by coconut shell for M20 grade. Eighteen specimens having a size of 600 x 150 x 150 mm were casted. Possibility and feasibility of flexural strength of coconut shell for beam specimens are determined respectively. The obtained results are compared with that of conventional mix. From study, we find out the optimum percentage for replacement of coarse aggregate by coconut shell and we can encourage the use of these seemingly waste products as construction material in Civil Engineering.
