Utilization of coconut shells in concrete

This research effort covers utilization of coconut shells in concrete. The use of coconut shell as partial replacement of coarse aggregate should be encouraged for sustainable and ecofriendly construction. Experimental results and discussion show that the coconut shell has potential as lightweight aggregate in concrete. It is concluded that the Coconut Shells are more suitable as low strength-giving lightweight aggregate when used to replace common coarse aggregate in concrete production. Coconut Shell Concrete can be used in rural areas and places where coconut is abundant and may also be used where the conventional aggregates are costly. The results conclude that the concrete with coarse aggregate partially replaced with coconut shell shows lesser strength but can recommended for low cost construction. The Coconut shell is about 60% lighter than conventional coarse aggregate. The coconut shell in concrete produce a harsher mix.
