Abstract

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.
