Why We Test Concrete Compressive Strength after 28 Days?

So, since the concrete strength is 99% at 28 days, it's almost close to its final strength, thus we rely upon the results of compressive strength test after 28 days and use this strength as the base for our design and evaluation.

CIP 35 - Testing Compressive Strength of Concrete

The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load

Properties of concrete - Wikipedia

In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
