Development and properties of composite cement reinforced coconut fiber with the addition of fly ash

Cement reinforced with 9 wt. % coconut fiber composite gave a better mechanical properties compared to others with highest values in compressive strength (58.98 MPa) and MOR (15.81 MPa).

From this research, it was found that the coconut fiber can be used as reinforcement and fly ash can be applied as a substitution of sand in the development of coconut fiber based-green composite. Increasing content of coconut fiber will increase the compressive strength and modulus of rupture until some optimum composition (9 wt. % of coconut fiber).
