Characterization of Coir Fibre Reinforced Geopolymer Composite

This paper mainly focused on the development of geopolymer technology by searching for
alternative aggregates commonly used, sand substituting with coir fibre as coconut tree is
abundant in Malaysia. As we know, sand is a limited source which one day may run out when
we used extensively. Thus, an alternative which can conserve this limited resource should
being developed for that purpose. In this research, we mainly enhanced the geopolymer by
improving with coir fibre with different fibre length and coir fibre mass composition. By
conducting different testing to obtain the data, we can evaluate the improvement whether had
achieved or not. The testing that had been chosen is Flexural Strength, Scanning Electron
Microscope and Water Absorption Test. The result from these testing will then discussed and
evaluate the suitable of coir fibre to replace sand as aggregate. This research is hoping give
the exposure to development of natural agriculture in enhancement structure application
