Innovation: Beus

Riese Electronic has developed an ultrasonic apparatus for precisely determining setting time tE of concrete and cement. The principle of action for determining the setting time is as follows: an ultrasonic sensor sends a measuring signal against a concrete cube; the reflected signal changes, depending on the hydration of the concrete. The advantage of this is that the results are objective and reproducible.

In addition to tE, the laboratory staff can determine and visualize the setting process. The device measures the course of hydration over a period of between 5 min. and 50 h; the measuring...
