Some aspects of image-processing-based method of measuring lateral deformation of hardening concrete – revised measuring technique

Abstract

The image-analysis-based measuring methods which process images of captured specimens cannot include the thin layer of the squeezed-out water to the total lateral deformation. This paper presents a revised measuring technique, which allows measurement of the lateral deformation including the contribution of the squeezed-out water. The major differences in the test configuration and image processing are described, and the applicability of results obtained is demonstrated on a real civil engineering problem.
