Why 28-day cube strength is not the whole story about concrete quality

The 28-day compressive strength test is the most common acceptance criterion for concrete — but it tells only part of the story. Water-cement ratio, curing conditions, admixture compatibility, and aggregate quality all play critical roles that a single strength number cannot capture.
