For concrete Class "C," what is the minimum compressive strength?

• A. 2,500 psi
• B. 3,000 psi
• C. 3,500 psi
• D. 4,000 psi

Answer: (B)

Concrete Class "C" is recognized for its application in various construction scenarios, where specific performance characteristics, especially strength, are crucial. Compressive strength is a vital property that indicates the concrete's ability to withstand axial loads. For Class "C" concrete, the minimum compressive strength specified is indeed 3,000 psi. This minimum strength ensures that the concrete mix used adheres to the performance standards required for structural applications, providing sufficient durability and load-bearing capabilities necessary for most general construction projects. Meeting this compressive strength threshold is critical for ensuring safety and the longevity of structures built with Class "C" concrete. Therefore, specifying 3,000 psi aligns with industry norms and standards that prioritize performance requirements in concrete formulation for adequate structural integrity.
