✦ Synopsis

In order to broaden the application of polymer concrete, the mechanical behavior of a polyester-based polymer concrete is investigated. The focus of the study is the compressive stress-strain relationship under lateral confinement. A total of 18 cylindrical specimens of 9-inch length and 3-inch diameter were tested under monotonic axial compression. The lateral confinement was provided in a passive way by aluminum rings uniformly spaced in a central confined zone of the test specimen. The degree of confinement was varied from specimen to specimen by changing the thickness of the rings. Test results indicate that the lateral confinement enhances the compressive strength in proportion to the confining stress and improves the post-peak behavior. An empirical formula is suggested to predict the compressive strength of the polymer concrete under lateral confinement. A simple equation for the compressive stress and strain relationship is also developed.
