Abstract
There are described methods and systems for handling fresh concrete inside a drum. In an aspect, a method of determining calibration data for use in determining workability of fresh concrete inside a rotating drum based on hydraulic pressure is described. This method has receiving a probe pressure value indicative of pressure exerted on a rheological probe mounted inside the drum and immerged in the fresh concrete; determining a workability value indicative of workability of the fresh concrete based on the probe pressure value and on calibration data for the rheological probe; receiving a hydraulic pressure value indicative of pressure of a hydraulic fluid used for rotating the drum; and determining hydraulic calibration data by associating the hydraulic pressure value and the workability value to one another.
