Abstract
The objective of the article is the discussion the different behaviors of several concrete types based on the DIC method. The three various concrete mixes were tested. They include two ordinary Portland cemented concrete mixtures having difference concrete grades and another concrete in which the steel slag replaced for coarse aggregate. During the beam-bending test, strain contour plots on the surface of reinforcement concrete beams and the crack development were captured of the digital image correlation (DIC) technique. The DIC method was verified by comparing the actual strain measured from the strain gauge and that determined from DIC. The results show the feasibility of using this method for present the strain contour plots of the reinforcement concrete beams. The crack development in various mixtures of concrete was compared and discussed within the article.
