Form3Dot1EstimationConcreteCompressiveStrength(
    beta_cc_t: DIMENSIONLESS, f_cm: MPA
)

Bases: Formula

Class representing formula 3.1 for the estimation of the concrete compressive strength, [\(f_{cm}(t)\)], after t days with an average temperature of 20 degrees Celsius.

[\(f_{cm}(t)\)] The estimated concrete compressive strength [\(MPa\)].

EN 1992-1-1:2004 art.3.1.2(6) - Formula (3.1)

Parameters:

  • beta_cc_t (DIMENSIONLESS) –

    [\(\beta_{cc}(t)\)] Coefficient dependent of the age of concrete [\(-\)].

  • f_cm (MPA) –

    [\(f_{cm}\)] Average concrete compressive strength on day 28 based on table 3.1 [\(MPa\)].

Returns:

  • None –
