Which of the following methods describes "cast in place" concrete?

The method that describes "cast in place" concrete refers to pouring the concrete into forms that are set up at the construction site. This approach allows for the concrete to be mixed, poured, and cured on-site, meaning it is constructed as part of the building's foundation, walls, or other structures right where they will be used. This method provides the advantage of creating a continuous structure without joints, which can enhance the strength and durability of the concrete.

In contrast, other methods involve different processes: pre-formed and cured concrete is typically fabricated in a controlled factory setting; stacked precast blocks imply that individual units are produced separately and assembled later; and dry mix delivery involves bringing in concrete materials that must be mixed with water on-site before being used. Thus, poured into forms on-site accurately captures the essence of what cast in place concrete entails.
