Abstract
A three-dimensional lattice approach for modelling the coupling of fracture and transport was applied to micro-cracking induced by aggregate restrained shrinkage in concrete, which was idealised as a three phase material consisting of matrix, aggregates and interfacial transition zones. Shrinkage of the matrix and interfacial transition zones was modelled by applying incrementally a uniform eigenstrain. The influence of aggregate diameter and specimen thickness on cracking and transport properties was investigated. The results show that increasing aggregate diameter at constant volume fraction increases the crack widths and, therefore, permeability, which confirms previously obtained 2D modelling results.
