STUDY ON PROPERTIES OF NATURAL FIBRE REINFORCED CONCRETE MADE WITH COCONUT SHELLS AND COIR FIBRE

Utilisation of agricultural waste material in concrete enhances the properties of concrete. To study this phenomenon concrete made of fly ash, coconut fibre and coir fibre for M40 was done and evaluated. Cement is substituted with fly ash by 10%, 20%, and 30%.Coir fibres is include by weight of the binder in the proportions about 0%, 1%, 1.5%, 2%, 2.5%, 3%. Coconut shells are replaced in the place of coarse aggregate. The breadth of coconut fibre will vary from 0.25 to 1.0 cm. The present study has illustrated that addition of coconut fibre and coir fibre to concrete enhances the properties of concrete.
