Abstract Concrete is intrinsically endowed with randomness on meso-scale due to the
random distribution of aggregates, mortar, etc. In this paper, two random medium models
of concrete mesostructure are developed and comparative studies are provided based on
random field representation approach. In the first place, concrete is considered as a kind
of one-phase random field, where stochastic harmonic function is adopted as the approach
to simulate the random field. Secondly, in order to represent the stochastic distribution of
the multi-phase of concrete such as aggregates and mortar, two-phase random field based
on the Nataf transformation and More >
