Dissolution and precipitation processes are present in key phenomena affecting the behavior of cement-based materials. Additionally, cement–based materials exhibit viscoelastic behavior. Recently, analytical homogenization tools have been developed to upscale the effective properties of composites in an ageing linear viscoelastic framework [1,2]. Taking advantage of these tools, an extension of Bazant’s original solidification theory [3] was proposed in a 3D tensorial context [4]. In this paper, we propose to benchmark these analytical approaches by comparing with numerical homogenization to estimate the behavior of ageing composites in different scenarios. To this end, 3D numerical samples are generated by randomly distributing inclusions of various sizes and shapes in a box [5,6]. We compare the response of solidification in two main morphologies: spherical and convex polyhedral inclusions. The results provided here go towards a better description of the dissolution/precipitation processes, which is an important feature in the characterization of cement-based materials ageing behavior.
