Performance Evaluation for Enhancement of Some of the Engineering Properties of Bamboo as Reinforcement in Concrete

Abstract

Bamboo is one of the alternative materials with strong potential for reinforcing the cement matrices. Unlike steel, during casting and curing of concrete, reinforced bamboo absorbs water and expands, which results in radial cracking of surrounding concrete. When curing is stopped, bamboo starts shrinking slowly loosing the contact with concrete. The dimensional changes of bamboo resulting from moisture and temperature variations, causes de-bonding which affects the bond strength severely. This paper presents the results of experimental investigations made to evaluate potential of bamboo to be used as concrete reinforcement. Specimens with and without node were extracted from well seasoned Dendrocalamus strictus variety of bamboo. They were tested for water absorption, dimensional changes, tensile and bond strength in M20 concrete with twenty different treatments. The paper also presents the comparison of bond strength of mild steel, TMT steel and untreated bamboo with that of bamboo having different low cost treatments for reducing the water absorption thereby enhancing bond strength of bamboo in concrete.
