The 28-Day Myth - National Precast Concrete Association

Oct 28, 2013 . When a failure occurs (commonly referred to as a “break”), the compressive strength is measured by dividing the force (lb) measured at the time the cylinder fails by the load-bearing surface area (sq in.) of the concrete sample. At the time of the break, the sample's age is generally noted for quality assurance.
