How is transit mixer capacity calculated?
Concrete carrying capacity of 1 Transit Mixer = 6 cum = 6 x 35.314 = 211.884 cft. As we Know that; Volume = Length x Breadth x Thickness. = 500 / 211.884 = 2.4 Numbers.
How long can concrete sit in truck?
Concrete can last for 3 hours in ready mix truck. If it is not unloaded it on time the slump value of the concrete changes. Solidification of concrete takes long time so to the max only slump changes.
How fast do concrete mixers work?
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) . In the United States, most ready-mixed concrete is mixed in trucks  and not pre-mixed in a plant. In a tilting drum mixer (Fig. 3), the inclination can be varied.
