Abstract

The invention concerns a method for controlling at least one workability parameter of concrete (14) contained in a container (12) of a mixer ( 11) with a non-vertical axis of rotation. The method comprises the following steps: rotating the container at at least two different rotational speeds; determining, for each of said rotational speeds, a rotary drive torque C of the container, a shear stress value τ of the concrete and a speed gradient ϒ of the concrete according to the following relationships: τ = T (ɷ) . C ϒ = G (ɷ) . ɷ where T and G are predetermined functions; determining a relationship of change of shear stress τ on the basis of speed gradient ϒ by extrapolation and/or approximation from the determined values; and providing an indication of the workability parameter of the concrete from the relationship of change.
