Abstract
The method of handling fresh concrete generally includes the steps of receiving a viscosity value of the fresh concrete and a pressure value of a pressure exerted on a Theological probe moving in the fresh concrete; using a processor, accessing at least two calibration data sets, the at least two calibration data sets including combinations of different reference pressure values and associated reference workability values for a corresponding one of at least two reference viscosity values; determining a viscosity difference value by comparing the received viscosity value to the at least two reference viscosity values; and determining a workability value of the workability of the fresh concrete based on the reference workability values associated with reference pressure values corresponding to the received pressure value in the at least two calibration data sets and on the viscosity difference value; and handling the fresh concrete based on the determined workability value.
