The International Organisation for Standardisation Technical Committee ISO/TC 77 defined that “Wood-fibre reinforced cement board consist of essentially of a mixture of wood fibres and Portland cement (or other cements with equivalent properties) to which other fibres, fillers and/or pigments may be added” [5]. Under this definition, sand is used as fillers. It is obviously that the fibre cement composite reviewed in this study uses short discrete fibres. Also, other definition of composite is a material made up of matrix material containing reinforcing fibres [1]. In this study, Portland cement is used as the matrix and oil palm fibres which are obtained from discarded oil palm tree, are used as reinforcing fibres. Fibre Reinforced Concrete is a concrete made of hydraulic cements containing fine or fine and coarse aggregate and discontinuous discrete fibres [6]. By incorporating fibres into cement matrix, some reinforcement is provided for the concrete products through interlocking of the fibres in the cement matrix [1]. The oil palm fibre cement board discussed throughout this study could generally be defined as a board consisting of a mixture of oil palm fibres in cement matrix manufactured. The main objectives of adding the oil palm fibres are to improve the strength properties of cement, control cracking and change the flow characteristics of the material in the fresh state. This is due to the fact that cement, mortar or concrete possess inferior tensile strength and are brittle, even though they are cheap, durable and have acceptable compressive strength and stiffness [1]. The presence of randomly mixed fibres in cement matrix will form an interlocking system among the fibres and thus provide additional tensile, flexural strength and fracture toughness for the products.
