Qs. How does a transit mixer work?

When the ready mixed concrete is transported to the construction site, the ready mixed concrete is pushed deeper into the drum attached to the back of the truck with the help of a spiral blade fitted within the drum. This is achieved by rotating the drum in one direction. This process is known as charging the transit mixer.At the construction site, the drum is rotated in the other direction, which forces the ready mixed concrete out of the drum. This process is known as discharging. The ready mixed concrete may be discharged directly into chutes, pumps or on to conveyor belts.

Qs. What are the dimensions of transit mixers?

The transit mixers are about 9 m long, 2.5 m wide and 3.8 m high

Qs. How do pumps work?

Pumps are designed to facilitate pumping of ready mixed concrete through the pipeline under high hydraulic pressure.When ready mixed concrete is pushed through the pipeline, it is separated from pipe line wall by a lubricating layer of cement, water and fine aggregates. Ready mixed concrete should have enough cohesiveness and workability for the mix to move easily through pipeline, bends, reducers and hoses.
