What is the term for the area of concrete that comes into contact with the forms?

Impact area
Contact area
Formwork area
Surface area

The correct answer is: Contact area

The term for the area of concrete that comes into contact with the forms is "Contact area." This term specifically refers to the surfaces of the concrete that are in direct touch with the formwork during the curing process. Understanding this concept is vital as it affects the finish and texture of the final concrete surface. The contact area can significantly influence the overall quality of the concrete, determining aspects like surface smoothness and adherence to the formwork, which can be critical in construction and architectural applications. The other terms, such as "Impact area," "Formwork area," and "Surface area," do not specifically refer to the context of the area where concrete meets formwork, making them less suitable in this instance.
