| 要旨 | INTRODUCTION Cement based products reinforced with natural fibers in appropriate field of applications is very significant from economic and technical point of view. Its low-cost and easy replenishability are some of its many distinct advantages, which when fully harnessed can lead to energy and scarce resources conservation. Technical merits of natural fibers in cement matrices like delaying of tensile cracking, improvement of postcracking strength, and toughness have been reported. One hindering factor to the extensive use of natural fiber is its inherent low-modulus of elasticity, and low-durability in an alkaline medium. However, appropriate short ranged application like pre-cast formworks, and piling shells-cap can adopt such kind of fiber as a support or main reinforcement. If these are the intended applications of the fiber composite, then it is necessary to study exhaustively the properties of this kind of material. This paper describes the results of comprehensive experimental evaluation of the fresh and mechanical properties of a particular natural fiber cement composite, namely a cement mortar/concrete reinforced with short randomly oriented coir fiber. CONCLUSION This study indicates that the utilization of coir fiber derived from the residues of coconut husks can provide solutions to two significant problems, namely, elimination of solid wastes and the provision of a valuable construction material. Based from this experiment the feasibility of using the coir fiber in construction is very significant, and from these improved understanding of the structure-property of the coir fiber cement composite it may be possible to find new ways to apply such kind of material as reinforcement not only to cement matrices but also to other kinds of materials. |
