Abstract

This study investigated the young and mature coconut fibres as asbestos replacement in fibre- cement flat sheet. The ratio of fibre content was ranged from 5–9.5% with an increment of 0.5% by weight of binder. Moreover, crushed rock dust (CRD) was also utilized in this study at ratio of 50% as sand replacement. The results showed that the addition of young coconut fibre (YCF) and mature coconut fibre (MCF) in flat sheet increased with the decreasing of bulk density and thermal conductivity. The optimum fibre content was used at 6.5-7% by weight of binder for two types of fibre with the highest flexural strength of 12–13 MPa. Especially, the modulus of rupture and density of fibre- cement flat sheet used YCF were higher than that of fibre- cement flat sheet used MCF, which is clarified by SEM results due to denser structure of MCF. Moreover, the modulus of rupture was directly proportional to the modulus of elasticity in fibre- cement flat sheet.
