Fundamental study on estimating compressive strength of concrete by changing lightness based on moisture movement of concrete surface

Abstract

This paper is testing to nondestuctively estimate of compressive concrete by changing lightness of concrete surface by moisture movement on concrete surface part by using image processing. In this report, as a fundamental study, concrete specimen. As a result, the higher water to cement ratio, the time for moisture movement is shorter, so that, we forecast we are able to estimate of compressive strength of concrete by changing lightness of concrete surface by moisture movement.
