behavior of polyester polymer concrete (PC) was investigated. The compressive and tensile
strengths of the optimum PC were 55 and 7 MPa, respectively. PC systems with fibers were
optimized based on the workability and mechanical properties. Fibers improved the
properties of the PC system to varying degrees, which depended on the type and amount of
fibers. The tensile-to-compressive modular ratio for the PC was 0.75. Strength, stiffness, and …
