Properties of polyester polymer concrete with glass and carbon fibers

In this study, the effect of adding glass and carbon fibers on the compressive and tensile 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 stress-strain models were used to predict the observed behavior of PC. The pulse velocity method and the impact resonance method were sensitive to determine the changes in nondestructive properties of PC systems with the addition of fibers. The pulse velocity method predicted the static moduli more closely than the impact resonance method. The damping properties of polymer concrete systems have been quantified.
