Numerical and statistical analysis of elastic modulus of concrete as a three-phase heterogeneous composite
We analyze the influence of aggregate and ITZ on elastic modulus of concrete. Ramesh model can theoretically estimate the elastic modulus of concrete. Soft ITZ can greatly cancel the enhancement of aggregate on elastic modulus. The RVE size of concrete is determined through numerical-statistical approach.
