Properties of concrete modulus of elasticity (AASHTO

The modulus of elasticity of concrete is a function of the modulus of elasticity of the aggregates and the cement matrix and their relative proportions. The modulus of elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. The elastic modulus of the hardened paste may be in the order of 10-30 GPa and

Secant Modulus of Elasticity an overview ScienceDirect

The strain at loading is classified as mainly an elastic strain and corresponds to the secant modulus of elasticity at the age when the load is applied. For the sake of accuracy, it should be noted that, since both concrete and masonry mature with age, the modulus of elasticity increases with time so that the elastic strain decreases with time under a sustained stress (see Figure 2.4 (b)).
