Concrete mixed in transit. The drum is turned at medium pace or about eight rpm for 70 revolutions although driving to the job internet site. The drum is then slowed to agitating velocity.
Most or all h2o is generally batched with the plant. The mixer drum is turned at charging (rapid) pace in the course of the loading in the resources. You will discover 3 choices for truck mixed concrete:
