Introduction. Three different soil samples were sourced and mixed with different percentage proportions of coconut fiber (0.1%, 0.3%, 0.5%, 0.7%, 0.9%, 1.0%, 1.2% and 1.5%). Traditionally coconut coir fiber is only used for brooms, mats, ropes and tools of other household. Mechanical and dynamic properties of coconut fibre reinforced concrete The research was carried out using paving blocks with dimensions of 20cm×10cm×6cm, mixed with coir fiber by 0%, 0.1%, 0.2%, and 0.3% by weight. Mixing coconut shell powder with epoxy resin enhances its properties and creates a wide range of applications. In the present work the mechanical properties namely tensile and flexural properties are evaluated by preparing composites using coconut coir fiber and coconut shell powder by mixing with polymer. Chemically treated coir fibre reinforced specimens yielded better mechanical properties compared to the raw ones. Also it is capable of taking strain, four times more, than other fibres. Alkali treatments (NaOH) Alkali treatments caused maximum weight loss (9.3 ± 1.5%) and also changed the colour of the fibres from pale yellowish brown to dark brown.
