"The paper presents comparison of results of two methods for Young's modulus evaluation of concrete specimens. The dynamic Young's modulus was calculated based on measured natural frequencies of longitudinal vibration of concrete specimens. The excitation was done by the impact hammer and the response was measured by piezoelectric acceleration transducer. Natural frequencies were evaluated from resonant peaks of Frequency Response Functions (FRF). Then the standard destructive compression test was done. At the end of the paper, the results of comparison of static and dynamic moduli of elasticity are summarized."@en . "4"^^ . "Metallurgy" . . . . . . .
