Brick aggregate concrete, stone aggregate concrete and recycled aggregate concrete columns confined with fiber reinforced polymer wraps were tested under compression to study the axial capacity enhancement due to confinement. Columns made of brick aggregate concrete and recycled aggregate concrete were measured to dilate larger than those from stone aggregate concrete. This resulted in higher capacity enhancement in those concrete columns than stone aggregate concrete columns. Increase in confining radius of curvature was found to be further beneficial in capacity enhancement for all concretes. The PM interaction diagrams plotted from the test results show the necessity of adopting higher safety factors than those presented in Bank (2006) for square columns of all concrete types.
