Extracted features from acoustic Impact-Echo method and image processing procedure of thermally degraded concrete specimens

The data set conatin 44 features of 197 concrete test specimens degraded by 200, 400, 600, 800, 1000, 1200 °C and refference set. The features are parameters of aocustic signals obtained by NDT method Impact-Echo and image parameters obtained by image processing algorytm of surface macrotexture of concrete specimens.
