An Experimental Study on Behaviour of Bamboo Reinforced Brick Aggregate Concrete Beam

Abstract

Bamboo is a giant grass which generally grows in the tropical and subtropical region around the world. The tensile strength of bamboo which is found to be significantly high makes it suitable to be used as reinforcing material with concrete. It is termed as bamboo reinforced concrete (BRC). In some parts of the world stone aggregate is poorly available and crushed brick is widely used as coarse aggregate in concrete which is termed as brick aggregate concrete (BAC). In the North eastern part of India especially in Tripura the availability of bamboo is enormous and brick aggregate concrete is very widely used. So, in this study an attempt has been made to utilize splint of Bambusa Balcooa species as reinforcing material in the brick aggregate concrete for making concrete beam. Beams using different percentage of bamboo reinforcement were prepared and test procedures were followed to evaluate ultimate load carrying capacity of bamboo reinforced beam. The average tensile strength of bamboo has been found as 287.69 MPa in this study. The ultimate load carrying capacity has found to be increased by 4.88 times in case of bamboo reinforced beam. Experimental results proved bamboo as worthy material to be used as a reinforcing material in concrete elements.

“…If bamboo is not coated with a waterproof layer, it will absorb each other and the bamboo will shrink as shown in Figure 1 [1]. Various types of waterproof coatings that are widely used include Sikadur ® -752 [2], [3], [4], [5], [6], Sikadur 32 Gel [7], [8], Sika Hibond [9], etc.…”
