Utilization of waste timber for construction industry using finger joint technique.

Abstract

Introduction: Timber was man’s first structural material and today is as important as ever for this purpose, it is likely, too through difficult to prove conclusively, that timber is used for a greater number of products than any other material [1]. While using timber in construction industry, waste timber materials and shorter section of timber which are dumped by sawmills is significant problem. Therefore, timber utilization is essential and timber utilization is urgently called by local timber industry due to the scarcity of timber species. In this case, the residues produced when using timber needs to be absorbed for suitable industries. Wastage of timber can be minimized by using proper machines and adopting new technology [2]. Finger joints (FJ) are described as interlocking end joint formed by machining a number of similar tapered symmetrical fingers in the ends of timber members using a finger joint cutter and then bonded together [3]. Using this method, wastes can be used as Finger jointed beams, boards and furniture in sustainable, eco-friendly way [4].
