ABSTRACT:
A reinforcement member for concrete bodies includes a bamboo rod having a roughened surface consisting of the bamboo cortex, and a substantially continuous coating of crystallized sulfur adhering to the roughened surface to prevent moisture absorption and swelling of the bamboo rod. The rod may have a helical wrapping of wire to further prevent swelling. The manufacture of the member includes roughening the rod by removing the bamboo article to expose the cortex, and dipping the rod in a bath of molten sulfur coating.
