Portable Concrete Rheometer

rheometer-removebg-preview.png

Most rheometer equipment conducts property tests in a fixed state in the laboratory, making it impossible to directly check the properties of ready-mixed concrete on site. However, Rhetribo is a portable concrete rheometer equipment that can be used to check the properties of ready-mixed concrete and predict pumping characteristics on site.

In addition to the ability to determine the viscosity and yield stress of concrete, the viscosity and yield stress of the lubricating layer formed on the pipe wall during concrete pumping can be determined through tests using a cylindrical cylinder.

Key Features and Usability

Static and dynamic tests can be selected, and the test method and test step (applicable RPS, application time) can be configured by the user, and the physical properties of ready-mixed concrete can be obtained through field tests without separate calculation work.

In the case of a tribometer, the material properties of the lubricating layer can be obtained, so the pumping pressure and discharge flow rate can be predicted from the relationship between the plug zone and the slip layer zone in the pipe during pumping.
