TESTING METHOD OF THE RHEOLOGICAL CHARACTERISTIC OF HIGH FLUID CONCRETE

摘要

In this study, the J*shaped tube test apparatus was developed to evaluate the Theological characteristic of high fluid 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 high fluid concrete are tested using this method. As a result, the flow viscosity coefficient and the shear stress yielding value of many kinds of the high fluid concrete are obtained. They are found to be similar to the values of the rotary viscometer. And the results are discussed in the rheological point of view, comparing them to the results of the conventional test method.
