This work evaluated and compared parameters of resistance of uniaxial compression of expanded polystyrene (EPS) with different densities when submitted to different execution speeds. The tests were performed according to ASTM 1621 with samples in four different specific masses (14.5, 18, 28 and 33.5 kg /m³) at speeds of 10 and 50 mm / min. The tests were conducted up to 24% deformation. Measures of resistance and modulus of elasticity parameters were obtained considering deformations of 1, 2, 5% (elastic limit) as well the maximum limit established (24%). Additionally, the parameters were analyzed and compared to the results of the literature (values ​​obtained in research and empirical correlations). The main results show, for instance, that the high EPS strength as a relationship between the deformability and strength of the material with its specific mass (as the density of the material increases, its resistance and deformation properties also increase). In addition, a correspondence was found between the specific deformation in the flow and the test velocity variation. The same was observed regarding the modulus of elasticity of the material.
