摘要：
In this work, the evaluation of measurement uncertainty of concrete dynamic elastic modulus testing method was conducted. The dynamic test was carried out using impulse excitation and modal analysis method, which can be used to determine the compressive strength of concrete in a non-destructive way. The tests were conducted using concrete samples in order to determine the practical usefulness of the mentioned method. It has been demonstrated that the impulse excitation and modal analysis method is characterized by very good repeatability.
