Previous studies on coconut fibre reinforced concrete, and coconut shell concrete showed the potential of these wastes to be used as alternative materials in building construction. Presence of coconut fibre and coconut shell gives beneficial to concrete in increasing concrete toughness and produced lightweight concrete. In this experimental study, a combination of these coconut components (fibre and shell) was used as concrete composite to investigate its physical properties and compressive strength. Three types of concrete were cast, i.e. normal concrete, coconut shell concrete and coconut fibre reinforced coconut shell concrete. The amount of coconut fibre added in coconut shell concrete was 0.5% of mass volume. The results showed that replacing aggregate with coconut shell reduced the concrete density and compressive strength. Additional coconut fibre aided in holding the coconut shell concrete material and improve the slump value.
