Compressive strength is the maximum compressive stress that, under a gradually applied load, a given solid material can sustain without fracture. Compressive strength is calculated by dividing the maximum load by the original cross-sectional area of a specimen in a compression test.

Breaking concrete from the outside requires overcoming its compressive strength. If, however, it can be broken from within, it’s only necessary to overcome the tensile strength which is about 15% of the compressive strength.

The 28-Day Myth - National Precast Concrete Association

Measuring the compressive strength of concrete is achieved by taking a sample of concrete at the time of placement. Cylinders, measuring 12 in. high by 6 in. in diameter, or 8 in. by 4 in., are compressed by a break machine that exerts increasing force upon the cylinder until it structurally fractures.

Tension Vs. Compression of Concrete | Hunker

Steel has great tensile strength; it bends without breaking. The combination produces the strength needed for bridge girders, roadways, building walls and other construction. An even stronger combination is prestressed concrete. The reinforcing steel is stretched or put under tension before concrete is poured around it.
