Abstract
A method for mixing concrete constituents that generally has a step of rotating a drum having a probe mounted inside the drum and immerged in the concrete constituents being mixed inside the drum; a step of receiving a first set of pressure values indicative of pressure exerted on the probe by the concrete constituents, the pressure values of the first set being taken at different circumferential positions of the probe during a single rotation of the drum; a step of determining a deviation of the pressure values of the first set from reference data; and a step of reducing a rotation speed of the drum upon determining that the deviation is lower than a threshold value.
