Concrete

Compressive strength, f'c:
MPa
Concrete density, γc:
kg/m³
info
Concrete density γc is used in Equation 8.1 for the modulus of elasticity, valid for 1500 < γc < 2500 kg/m³ (CSA A23.3-19 Clause 8.6.2.2).

Density Class

Modification factor, λ:
info
λ accounts for concrete density (CSA A23.3-19 Clause 8.6.5): 1.00 for normal-density; 0.85 for structural semi-low-density concrete in which all the fine aggregate is natural sand; 0.75 for structural low-density concrete in which none of the fine aggregate is natural sand.
