Increasing performance of bamboo reinforced concrete beam with addition of bamboo pegs on the reinforcements

This research investigated the effect of adding pegs along the bamboo reinforcement in order to increase the bonding strength of bamboo reinforcement. Present experiment employed 24 beam specimens, sized 18 cm x 28 cm x160 cm. The variations of the concrete materials were 23 MPa and 31 MPa with 6 cm and 12 cm peg spaces, and reinforcement ratio of 0.8% and 1.6%. Two Control specimens conducted without pegs along the beam were made from 23 MPa concrete strength with reinforcement ratio 0.8%, and a 31 MPa concrete beam with 1.6% reinforcement ratio. By using pegs along the reinforcements, all specimens showed higher strength capacity of beam structures. Moreover, the addition of pegs caused the bamboo to reach 70% of its maximum strength.
