Ready Mixed Concrete (RMC) • In the plant mixed type, the mixing is done at a central batching plant and the mixed concrete is then transported, in special agitator truck. The agitator truck keeps the concrete moving along a circular path at about 2 to 6 revolutions per minute, so as to prevent segregation and undue stiffening of the mix.
