Compressive strength, modulus of elasticity, and water …
Normally, the elastic modulus of concrete relates to its compressive strength as the simple equation (3), (3) E = σ ε where E is the modulus of elasticity (MPa), σ is the compressive stress (MPa), and ε is the strain value (dimensionless). Naturally, strain along the time of concrete-like materials would slightly decrease after hardened.
