Abstract

The method can determine a density of concrete based on the measured buoyancy of a buoy immersed in fresh concrete contained in a ready mix drum and rotatable therein as the drum is rotated, the method can include obtaining a first measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete, obtaining a second measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete by rotation of the cylindrical wall, obtaining an indication of the buoyancy of the buoy in the concrete including factoring out the yield effect based on at least the first measurement and the second measurement.
