Precast concrete involves concrete that is cast, cured, and transported to the site.

• A. Cast in place concrete
• B. Precast concrete
• C. Cast on-site and cured there
• D. Post-tensioned concrete

Answer: (B)

Precast concrete is manufactured away from the building site in a controlled environment, then cured and transported to the site for installation. That off-site production and the subsequent transport to the job location define precast.

So the description fits precast concrete because it emphasizes casting, curing, and moving the finished elements to the site. Casting and curing on site describes cast-in-place work, not precast. Post-tensioned concrete refers to the method of tensioning steel tendons and can be used with either precast or cast-in-place systems, but it does not define precast itself.
