Measuring device and measuring method of concrete viscosity

Abstract

A measuring device and a measuring method of concrete viscosity relate to measuring devices and measuring methods and aim at resolving the problem that the existing rheometer and viscosity meter are apt to separate aggregate and slurry, cannot enable concrete to form stable and homogeneous laminar states and are not accurate in measurement of shearing moment when measuring concrete rheology parameter and the appliances are complex in structure and high in construction cost. The measuring device comprises a container, a steel cylinder, a tray, a press disc, a container cover and an electronic scale. The tray is arranged on the bottom face of a container inner cavity, the press disc is arranged at the position of a container opening of the container, the lower end of the steel cylinder penetrates through a center hole of the tray, the upper end of the steel cylinder sequentially penetrates through a center hole of the press disc and the center hole of the container cover from bottom to top, the upper end of the steel cylinder is connected with the lower end of the electronic scale through a dowel, and threads are arranged on the outer lateral wall of the steel cylinder. The measuring device and the measuring method are used for measuring viscosity of concrete.

Description

technical field [0001] The invention relates to a measuring device and a measuring method, in particular to a measuring device and a measuring method for concrete viscosity. Background technique [0002] The measurement method of the rheological properties of fresh concrete, according to the theory proposed by the famous scholar Bingham, at least needs to measure the yield stress viscosity and plastic viscosity of concrete. In order to measure these two parameters, foreign scholars have made a lot of improvements to the existing traditional viscometer. The famous scholar G.H.Tattersall and his students had designed different types of stirring paddles. Scholars in Japan and Europe have also changed the structure of the existing viscometer and done a lot of experimental work. However, the experimental reports and related curves of the rheological parameters of scholars from various countries are far from each other, and the conclusions of the experimental reports are very inc...

Problems solved by technology

[0003] The present invention solves the problem that when existing rheometers and viscometers measure the rheological parameters of concrete, it is easy to separate the aggregate from the slurry, and the concrete cannot form a stable homogeneous laminar flow state. The measurement is not very accurate, the instrument structure is complicated, and the cost is high, and then a measuring device and method for measuring the viscosity of concrete is proposed
