"Specifications for Structural Concrete for Buildings (ACI 301-72, Rev. 1981)" states: "Concrete shall be handled from the mixer to the place of final deposit as rapidly as practicable by methods which will prevent segregation or loss of ingredients and in a manner which will assure that the required quality of the concrete is maintained." Correct handling can reduce final cost and maintain concrete quality. Handled improperly, unnecessary additions to the final cost can result and concrete quality will suffer.

The best method for the transportation and distribution of concrete can be selected after considering the following: Conditions of the jobsite (location of trees and adjacent buildings, effect of noise on neighbors, land contours, and the need for all-weather access); availability of equipment; continuity of concreting; season of construction (hot/cold weather requirements); temporary improvements which may be required for work to proceed; maintaining uniformity; and concrete specification.

Transporting the concrete can be covered by a simple paragraph such as the ACI specification cited. This wording leaves the choice of method open, the only restriction usually being an added section stating: "Placing shall be carried on at such a rate that the concrete which is being integrated with fresh concrete is still plastic. Haulage distances may be great for ready mixed concrete trucks and, coupled with the time the concrete may wait in the drum because of delays at the site, the time limits should be looked at carefully. They may be a factor in selecting the conveying method to use. If delivery will be in 8-cubic-yard batches, be prepared to unload and place that volume quickly."
