ABSTRACT
The objective of all supply and handling must be to provide concrete in sufficient quantity, of acceptable quality and of suitable workability at the point of placing to enable the construction to proceed systematically and economically. Determination of the means of batching, mixing and handling concrete are generally critical decisions made in the precontract planning stages. The plant selected will be based on a number of factors:
site location and available space; service availability; scale of operation; location of batching plant; distance of transport; type of concrete to be produced; required rate of placement; ground conditions; tide or flow conditions in or over water; detached operations (jetty, tunnel construction, etc.); vertical and horizontal travel.
