Deformation behavior of epoxy-modified high strength concrete under uniaxial and repeated compression load

This study deals with the deformation characteristics of epoxy-modified concrete (EMC) under uniaxial and repeated compressive load with a view to evaluate its potential for use in structures that are subjected to in-service deformations under seismic conditions. A series of concrete specimens were prepared with epoxy resin either as the only binder or as co-binder jointly with the conventional binder, Portland cement. The specimens were evaluated on the basis of mechanical strength and deformability. The modulus of elasticity and the Poisson’s ratio of the EMC have been compared with conventional Portland cement concrete (CC).The first exhibits much higher axial and lateral deformation capacity than the later, a clear indication of higher energy-dissipation ability and ductility. © 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
