Webthe characteristic compressive strength: fck = 15 MPa and fck = 25 Mpa, from now on “HM-15” and “HM-25”. The elastic modulus E was determined through the formula proposed by the Spanish regulation EHE-98. According of this, the longitudinal deformation modulus relates to the compressive strength as follows: 8500 83 f pa E = +$ ck 6L @ WebJan 1, 1992 · The characteristic compressive strength fck is the first value in the concrete class designation, e.g. 30 MPa for C30/37 concrete. The value corresponds to the characteristic (5% fractile) cylinder strength according to EN 206-1. The strength classes of EN1992-1-1 are based on the characteristic strength classes determined at 28 days.
