The article presents a comparative analysis of the quantitative values obtained from the experimental tests, of the static and dynamic modules of elasticity (Young’s modulus) of gamma polymer-concrete composites. The same will be used as constructive material for parts and body elements. Standard test methods are applied. The values of the elastic parameters of the tested polymer-concrete composites are necessary as input data for the various engineering analysis softwares.

This article has experimental nature. The values of the dynamic elastic modulus (Young’s modulus) of gamma polymer concrete composites are determined quantitatively. The tested samples have the form of a rectangular parallelepiped (type bar).

The dynamic Young’s modulus of the samples is determined by the method of the experimental modal analysis. Impact excitation was applied for expressing the resonance frequencies in the tests of bending and twisting the sample. The test results were processed with regression analysis.

This research presents the experimental approach and methodics for quantification of the damping characteristics of two groups of polymer-concrete composites. By means of a comparative analysis here it is determined the influence of the type of fine filler material (microfiller) on the damping characteristics of the experimental polymer-concrete composites.
