Abstract

Bamboo is a rapid renewable plant that has a fast growth rate as compared to trees, which increases its suitability to be used as a sustainable source for wood industry, especially in construction works. Due to the lack of understanding on bamboo properties, the utilization of bamboo in construction has always been neglected. This paper presents an investigation on the mechanical properties of four species of treated bamboos that are available in Malaysia, which include Bambusa Vulgaris, Dendrocalamus Asper, Schizostachyum Grande , and Gigantochloa Scortechinii . A mechanical testing was carried out in various parts along the culm of these bamboo species in order to examine the differences of their compressive strength and tensile strength. The strength development and moisture content of these bamboo species were also monitored at a five-month interval. The results showed that Bambusa Vulgaris, Dendrocalamus Asper , and Gigantochloa Scortechinii possess excellent mechanical properties in compression and tensile strength, which indicate a good quality to be used as a construction material. As bamboo offers promising advantages, thus, it is suitable to be used as a substitute in place of structural timber in construction, which indirectly facilitates the preservation of the global environment.

Highlights

Being classified as a grass member of a larger grass family [1], bamboo can be found in tropical and some temperate areas of the world.Bamboo has a nature form comprising a cylindrical pole with jointed stem known as a culm
2.2 Mechanical testing All bamboo species were cut into small samples, in which the samples were taken from the internode of the bamboo culm
The results show that Bambusa Vulgaris exhibits an almost similar tensile strength as Dendrocalamus Asper, with bamboo’s top, middle, and bottom parts recorded readings of, 231.67, 233.98 and 230.63 N/mm2, respectively

Summary

Introduction

Being classified as a grass member of a larger grass family [1], bamboo can be found in tropical and some temperate areas of the world. Bamboo has a nature form comprising a cylindrical pole with jointed stem known as a culm. There are over 1500 identified bamboo species in the world [2]. As one of the fastest growing plants, bamboo can reach a full height ranging from 15-30m in a period of two to four months [3]. Each species can be identified according to their root system, in which there are three known root systems including, sympodial, monopodial, and amphodial [4]. The thickness of a bamboo decreases along the height of the culm, while the fibres density increases from the bamboo culm’s inner wall to outer wall
