The present study examines the performance of concrete modified with different percent of epoxy resin under various curing conditions. Different grades of concrete (M20, M25, M30) with different epoxy (resin hardener) - cement ratio were analyzed to determine the impact on the mechanical properties of the mixed concrete.72 specimens (36 cubes and 36 cylinders) for all the three grades (M20, M25, M30) with varying epoxy (resin hardener) - cement ratio by weight for each grade that is 5%, 7.5% and 10% were testified. Compressive strength as well as splitting tensile strength are evaluated for 7, 14, and 28 days. The results were then compared with the conventional concrete specimens for each grade at the respective ages. Results showed that the strength of samples depend on the amount of epoxy used and showed that the strength of Epoxy Mix Concrete (EMC) is having more strength than conventional concrete at the corresponding ages. Results also showed that there is a considerable decrease in slump and workability with the increase in epoxy -cement ratio and that the workability of conventional concrete is more than that of EMC.
