What are the typical components of concrete?

• A. Cement, water, aggregates, and metals
• B. Cement, paint, aggregates, and glass
• C. Cement, water, aggregates (fine and coarse), and sometimes admixtures
• D. Cement, gravel, aluminum, and sand

Answer: (C)

The typical components of concrete include cement, water, aggregates (which consist of both fine aggregates like sand and coarse aggregates such as gravel or crushed stone), and sometimes admixtures. Cement acts as the binding agent that holds the other materials together when it hydrates and hardens. Water is crucial as it facilitates the chemical reactions needed for cement to set and develop strength. Aggregates are essential as they provide the bulk and strength to concrete; fine aggregates fill the gaps between coarse aggregates, contributing to the overall performance and durability of the concrete mix. Admixtures may be added to enhance specific properties of the concrete, such as workability, setting time, or durability, depending on the project requirements. This comprehensive understanding of concrete's makeup is critical for achieving the desired characteristics in the finished product, making option C the most accurate choice.
