The purpose of this paper is to investigate and determine the material properties of the coconut shell fiber, to evaluate the microstructure of the ECC containing coconut shell fiber and to determine the hardened properties of ECC containing the coconut shell fiber. Emphasis on this study is based on the material properties of the Matag coconut fiber and the compressive strength of 18 different mixtures of ECC. The results indicated that the Matag coconut has a significant strength contributing to the development of ECC as well as an optimum mixture that is fit for application of 1% of coconut fiber in the mix proportion. Additionally, in the system of binder materials, various percentage volumes of silica fume is added whereby it improves the ductility and strength of the ECC with a certain proportion added respectively. Therefore based on numerous testing by comprehensively considering the compressive strength, flexural strength and direct tensile properties, the optimal range of ECC mixture with addition of coconut fiber can be properly selected to satisfy the demands in practical engineering solutions.
