Mar 01, 2001  Typically the speed for mixing is 1.57 rad/s (15 rpm), while the transport of pre-mixed concrete uses only 0.2 rad/s (2 rpm) to 0.6 rad/s (6 rpm) [ 1 ]. In the United States, most ready-mixed concrete is mixed in trucks [ 2] and not pre-mixed in a plant. In a tilting drum mixer ( Fig. 3 ), the inclination can be varied.
