CIP 35 - Testing Compressive Strength of Concrete254 Кб
Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) andpsi (35 MPa) It is important to understand that an individual test falling below ƒ´c does not necessarily constitute a failure to meet specification requirements.www.nrmca.org/aboutconcrete/cips/35p.pdfна сайте

Compressive Strength of Concrete
The compressive strength is measured by crushing cylindrical concrete specimens in compression testing machine.No single strength test should fall below fc' by more than 500 psi (3.45 MPa) or by more than 0.10fc' when fc' is more than 5000 psi (35 MPa).
