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.

本数据集涵盖197个经200℃、400℃、600℃、800℃、1000℃、1200℃高温劣化的混凝土试验试块，以及一组参照集的相关数据，共包含44项特征。这些特征分为两类：一类为通过无损检测（Non-Destructive Testing，NDT）方法冲击回波（Impact-Echo）获取的声信号参数，另一类为通过图像处理算法提取的混凝土试块表面宏观纹理图像参数。
