A New Approach Based on Image Processing for Measuring Compressive Strength of Structures

Abstract

The compressive strength factor in civil engineering is a very important parameter used to determine the performance ofstructures. The stability of structures can be tested with this parameter which is used to measure the performance of concrete under differentloads. This parameter, which should be determined for the safety of the structures, is usually based on experimental analyses performed inthe laboratory environment. In this study, a new approach to compressive strength measurement in civil engineering is proposed. With thisapproach, which is based on image processing, measurement of compressive strength parameter of concrete samples taken from structuresis performed. For this purpose, images of concrete specimens with different strengths are taken and these images are divided into twogroups as training and test set. Then, image processing algorithms are applied to these images and the compressive strength of concretespecimens is calculated. It has been determined that the approach suggested in the test runs performed with an error rate of about 1-2%.
