Under what circumstances might it be desirable to have a field batching plant for job-mixed concrete?
What will be an ideal response?
It might be desirable to have a field batching plant for job-mixed concrete when there is no existing ready-mixed companies close enough to supply the concrete or if the existing companies cannot handle the additional work of supplying a large project. It may be advantageous when there is a large volume of concrete to be poured, justifying the cost of setting up a batch plant.
