Quantification of plastic shrinkage cracking in mortars using digital image correlation

This study presents a digital image correlation (DIC) technique for the detection and quantification of plastic shrinkage cracking in thin restrained mortar overlays applied on concrete substrates. The non-contact 2D-DIC technique enables measurements of in-plane surface strain and displacement under continuous monitoring. A post-processing procedure to compute various crack parameters, such as crack location, width, length and area on the...
