Placing

Definition: the deposition, distribution, and consolidation of freshly mixed concrete in the place where it is to harden (often inappropriately referred to as pouring).- ACI Concrete Terminology


To provide durable concrete, it should be free of segregation and the mortar should be in close contact with the coarse aggregate, reinforcement, and any adjacent faces to which it is to be bonded. Concrete should be deposited, as nearly as practicable, in its final position. Placement of concrete is accomplished with buckets, hoppers, manual or motor-propelled buggies, chutes and drop pipes, conveyor belts, pumps, tremies, and paving equipment. Concrete can also be placed by the shotcrete process, in which layers are applied pneumatically. The shotcrete process is especially beneficial where forming is inconvenient or impractical, access or location provides difficulties, or normal casting techniques cannot be employed.
