the 28-day myth

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.

cip 35

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 divided by the cross-sectional area resisting the load and

3 ways to break up concrete

to break up concrete start by covering the concrete with a plastic sheet to protect nearby items from flying debris. for thin slabs of concrete use a sledgehammer to break it up. if the concrete is too thick to break up with a sledgehammer you can use an electric jackhammer instead.
