What term describes concrete that is prepared at a central plant and delivered to the site by a truck mixer?

• A. Admixtures
• B. Footing
• C. Concrete
• D. Ready-mixed

Answer: (D)

Ready-mixed concrete describes concrete that is manufactured in a central plant, where batching and mixing occur under controlled conditions, and then transported to the construction site in mixer trucks. This setup ensures consistent proportions, workability, and quality from batch to batch, since the mixing happens off site. Admixtures are additives added to modify specific properties but don’t define where or how the concrete is mixed. Footing is simply a type of foundation element, not the mixing method. Concrete is the generic material, while ready-mixed specifies that the mixing and delivery are done from a central plant.
