DEVICE FOR TESTING UNSET CONCRETE AND MORTAR

摘要

A rotary testing device can be connected to a base unit. A temperature sensor may also be connected to the base unit. The testing device has probe heads that are submerged and rotated in the fluid concrete, and the force required to rotate them is measured by the base unit. Various concrete recipes are stored in a memory of the base unit. Data concerning the concrete to be tested are calculated by comparison of the force required to rotate the testing device with the force derived from a respective characteristic curve and the calculated data are read from a display field. A concrete recipe and its specific measurements are selected by depressing keys by means of which are selected the respective electronic processes in the base unit for measurement and comparison with stored characteristic data.
