Development of data optimization methodology for non-destructive testing of concrete strength by the parameters of the electric response to impact excitation

Abstract

The paper presents the research results by the improvement of the non-destructive testing method of concrete strength by the parameters of the electric response to impact excitation. The electric response parameters from the set of identical concrete samples sized of 100x100x100 mm were studied. It is shown that the use of linear filtering procedure reduces the variance of diagnostic electric parameter for concrete strength determination and is in a good agreement with the elastic characteristics of the material.
