Stub column tests of FRP-confined rubber concrete with various replacement ratios

The practical application of rubber concrete has so far been mainly limited to non-structural use due to its disadvantages induced by the rubber particles, such as the relatively low compressive strength and early cracking. One effective way to overcome the detrimental effects of these disadvantages is to use fibre reinforced polymer (FRP) as an external confining device to confine the concrete. In this paper, results from a series of stub column tests on FRP-confined rubber concrete with various replacement ratios are presented. The test results confirmed that the FRP confinement is effective in improving the strength and ductility of rubber concrete, and that the replacement ratio has a smaller effect on the strength of FRP-confined concrete than on the unconfined concrete.
