Abstract
A concrete mixing system includes a vehicle, a rotatable mixing drum coupled to the vehicle, an incline and/or slump sensor, and a controller. The controller is configured to effect a change of rotational speed of the rotatable mixing drum in response to a signal from at least one of the sensors indicating an increased likelihood of spillage of concrete from the rotatable mixing drum.
