| Research Abstract |
Purpose of this study is construction and quantification of rheological model of fresh concrete. Formularization of Visco-plastic flow model of fresh mortar considering dilatancy property was carried out based on experimental results by using of rotation visco meter. And influences of admixtures, time course, air content and shear strain acceleration on suggested model were clarified. At the last, a prototype rheometer for fresh concrete was built.
