Batching, Mixing, Transporting, and Handling Concrete

Truck-mixed concrete is mixed completely in a truck mixer (top right). 70 to 100 revolutions of the drum or blades at mixing speed are usually required to produce the uniformly mixed concrete. The homogeneity of concrete is maintained after mixing and during delivery by turning the drum at agitating speed. Agitating speed is usually about 2 rpm to 6 rpm, and mixing
