A multi-layer approach to classify the risk of corrosion in concrete specimens that contain different additives

Abstract

There are many different ways to estimate whether a concrete structure will be suffering corrosion degradation as experimental processes and numerical estimations relied on theoretical equations. Nevertheless, these estimations require higher certainty and satisfactory estimation accuracy. Deep Learning is causing profound changes in society. It has inspired unprecedented advances in historically challenging problems. This paper proposes a mathematician approach. A Deep Learning model capable of classifying the risk of corrosion on concrete specimens relied on a standard methodology. It employs the Electrical resistivity measurement for achieving this goal. The deep neural network architecture presented in this study displays a merging of activation functions. Also, a regularized method to avoid overfitting problems was implemented. The model comprises different standard tests as input data and classification of the corrosion risk as output. The outcomes depict an accuracy of about 98%, given the nature of the stochastic learning algorithm. Different concrete samples were analyzed in this research in order to provide data variety to the algorithm and accomplish a robust and stable model.
