In this study, the aggregate of polymer concrete is made using pumice stone, sand, solid waste rubber thread, and polyurethane as a binder. Variation of composition of sand and pumice are (1: 1) or (50 g: 50 g); solid waste rubber thread are (0, 2, 4, 6, 8, 10)% of the total weight of sand and pumic; while composition variations of polyurethane are (10, 15, 20)% of the total weight of sand and pumice. The measured parameters of samples are density, water absorption, porosity, compressive strength, impact strength, flexural strength, microstructure analysis using Scanning Electron microscope (SEM), XRD analysis and sound absorption coefficient. Based on this research, it is showed that the optimum conditions of fabricated polymer concrete characteristics are with density of 1.67 g/cm3, water absorption of 13.25%, porosity of 19.85%, the compressive strength is 8.59 MPa, impact strength of 5.2 kJ, and flexural strength of 50.33 MPa). The sound absorption coefficient of the best sample is 0.196. This polymer concrete is lighter than conventional concrete and has better strength and sound absorption coefficient.
