Concrete can be cast to any shape prior to curing is known as

• A. Formability
• B. Ductility
• C. Malleability
• D. Workability

Answer: (A)

Formability captures the ability of concrete in its plastic state to be deformed and filled into the desired form before it hardens. When the mix has good flow and consistency, it flows around reinforcement and into intricate formwork, taking the shape you’ve designed prior to curing. Ductility describes how a material stretches under tension after it has set, which is not about shaping the material before it cures. Malleability is a term more often used for metals to deform under pressure and isn’t the standard way to describe concrete behavior. Workability is a broader idea that includes how easy it is to mix, place, and finish concrete, but the specific notion of casting into arbitrary shapes before setting is best described by formability.
