Which of the following is a common use of concrete?

• A. Steel Beams
• B. Glass Windows
• C. Foundations and Footings
• D. Wooden Beams

Answer: (C)

Concrete is typically used for foundations and footings because it provides a solid, durable base that can be poured and formed to spread a building’s loads over a larger area of soil. This helps prevent excessive settlement and keeps the structure stable over time. In foundations, concrete carries vertical loads and resists moisture and weathering, and when reinforced with steel, it also handles bending and tension where needed. Other options listed involve different materials—steel beams are metal framing, glass windows are glazing, and wooden beams are timber—so they don’t represent the common base element that transfers loads from the structure to the ground. Foundations and footings are where concrete most prominently serves its essential structural role.
