What components make up a standard concrete mix ratio?

• A. Cement, sand, water
• B. Concrete, sand, and gravel
• C. Cement, aggregates, and water
• D. Cement, sand, and coarse aggregate

Answer: (D)

The correct composition of a standard concrete mix ratio includes cement, sand, and coarse aggregate. This selection aligns with the basic elements required to create concrete that meets structural performance standards. Cement acts as the binding agent, which hardens and sets to hold together the other materials. Sand serves as the fine aggregate that fills in the spaces between larger aggregates, ensuring a workable mixture and contributing to the overall strength and durability of the concrete. Coarse aggregate, which typically consists of gravel or crushed stone, provides the bulk and structural integrity, enhancing the load-bearing capacity of the concrete. Together, these components create a versatile material that can be used in a wide variety of construction applications. Understanding the role of each component is essential for achieving the desired properties of concrete, such as workability, strength, and durability, which are critical for ensuring successful construction projects.
