Strength development in concrete - Understanding Cement

For example, a cement described as conforming to EN 197-1 CEM I 42.5 N would be expected to achieve at least 42.5 MPa at 28 days using the specified mortar prism test. Whether 'real concrete' made from that cement will achieve 42.5 MPa in concrete cube tests depends on a range of other factors in addition to any intrinsic properties of the cement.
