What does the term "2500 concrete" indicate regarding compressive strength?

Supports 2500 pounds per square inch after 7 days
Weighs approximately 2500 pounds per cubic yard after curing
Can safely support 2500 pounds load after 28 days
Has tensile strength of 2500 pounds per square inch

The correct answer is: Can safely support 2500 pounds load after 28 days

The term "2500 concrete" specifically refers to the compressive strength of concrete measured in pounds per square inch (psi) after a curing period of 28 days. Concrete achieves its intended strength progressively as it cures, and the industry standard often uses the 28-day mark for evaluating its performance. Therefore, "2500" signifies that the concrete can safely support a compressive load of 2500 pounds per square inch after this duration, which is essential for structural integrity assessments. Compressive strength is a critical property for determining how much load concrete can withstand in construction applications. Understanding this metric helps construction supervisors ensure that materials meet safety and design requirements.
