BAMBOO REINFORCED CONCRETE CONSTRUCTION

1. INTRODUCTION. The use of bamboo as reinforcement in portland cement concrete has been studied extensively by Clemson Agricultural College.(ref 1) Bamboo has been used as a construction material in certain areas for centuries, but its application as reinforcement in concrete had received little attention until the Clemson study.
