Mechanical Properties and Performance Assessment of Polymer Concretes

Polymer concretes (PCs) have emerged as high-performance materials offering superior strength, durability, and chemical resistance compared to conventional cementitious composites. This study presents a comprehensive experimental program designed to investigate the relationship between microstructural characteristics and mechanical performance of PCs. Mechanical properties were evaluated through strength, stiffness, durability, and integrity tests, while microstructural features were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). The results reveal a clear link between refined microstructure, reduced porosity, and enhanced mechanical behavior. This integrated approach provides new insights into the performance mechanisms of PCs and establishes a scientific basis for their broader structural use in demanding environments.
