Abstract

This paper presents the study into the mechanical properties of concrete incorporating coir fibre from North Sulawesi, Indonesia. Coir is a resilient natural fibre obtained from the husk of coconut fruit. The main objective of this research is to justify the usage of local natural resources in North Sulawesi as an alternative construction material by finding the optimum fibre percentage that can be used to achieve improved mechanical strength. Combining coir in the concrete mixture offers the potentiality of developing a high quality, economical and environmentally friendly construction material. Specifically, this research evaluates the compressive strength, flexural strength and split tensile strength of concrete samples containing variations of coir percentage of 0%, 0.25%, 0.5%, 0.75%, and 1% by weight of aggregates. Laboratory tests were conducted based on Indonesian National Standard (SNI) and American Society of Testing Materials (ASTM). Slump tests performed before casting of samples showed that the workability of concrete mixtures was reduced when fibre content was increased. Results of the mechanical properties tests showed that the 0.25% samples (BS-0.25) achieved optimum values of compressive strength and flexural strength.
