DEVICE FOR MEASURING CONSISTENCY OF FRESH CONCRETE AND SEGREGATION RESISTANCE EVALUATION TEST METHOD

摘要

PURPOSE: To clearly measure two properties of the a degree of soft of fluidity and viscosity by providing a shutter means for allowing a sample with which the vessel part is filled to flow to a fluidity part in the boundary of a sample outflow side of the vessel part and a sample inflow part of the fluidity part. ;CONSTITUTION: A base 8 is horizontally installed by adjusting level adjusting bolts 9, and a fluidity part 2 is also horizontally adjusted by using a level vial. A measuring device consists of a vessel part 1, the fluidity part 2 and a shutter means 4, a shutter 7 of the means 4 is set on guides 14a, 14b, and the outflow side of the vessel part 1 is closed by the shutter 7. And, after the vessel part 1 is filled with a sample and an upper face is averaged by being matched along the upper part of the vessel part 1, immediately the shutter 7 is opened, and the sample is allowed to flow out to the fluidity part 2. The degree of soft of fluidity of the sample is measured in accordance with a distance where the sample is allowed to flow in the fluidity part 2. In addition, after the shutter 7 is opened, a time for reaching a specified fluidity distance in the fluidity part 2 is measured, and a flow speed of the sample is found.;COPYRIGHT: (C)1996,JPO
