Abstract

In this study, the J shaped tube test apparatus was developed to evaluate the rheological characteristic of the high-fluidity concrete by measuring the flow viscosity coefficient and the shear stress yielding value of the concrete. To examine the applicability of this test method, many kinds of the high-fluidity concrete are investigated experimentally.As the result, the flow viscosity coefficient and the shear stress yield value of many kinds of the high-fluidity concrete are obtained, which are found to be similar to the values of the rotary viscometer. And the rheological consideration about these results is carried out, comparing the results of the conventional test method.
