CIP 35 - Testing Compressive Strength of Concrete

2013-5-10  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 reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units. Con-crete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa)

Compressive strength testing of high performance

1996-12-1  Two different cylinder end conditions were considered; namely, "regular" ground ends, and capped ends with confining rings (confined caps developed at the Lakehead University). Capping compound--having the manufac- turer's specified ultimate compressive strength of 35 MPa after 5 min and 55 MPa after 48 hIWaS used for making the confined caps.

Standards for 7-day and 28-day strength test results

Every arithmetic average of any three consecutive strength tests equals or exceeds the specified compressive strength. No strength test falls below the specified compressive strength by more than 500 psi (3.5 MPa) if the specified compressive strength is 5000 psi (35 MPa) or less; or by more than 10 percent of the specified compressive strength if the specified compressive strength exceeds 5000 psi (35 MPa).
