Numerical modelling at the mesoscale is a time-and cost-efficient tool to optimize concrete
mix design and to analyse the phenomenological causes of mechanical failure, eg when …

This paper presents a meso-scale modelling framework to investigate the fracture process in
concrete subjected to uniaxial and biaxial compression accounting for its mesostructural …

The interfacial transition zone (ITZ), located between aggregate and cement paste, has the
features of high porosity, low unhydrated cement content, and enrichment of calcium …

This work modified recycled aggregates (RAs) by soaking them in a nano-silica (NS)
suspension and evaluated the modification effects on recycled aggregate concrete (RAC) …

The realization of approximate practical aggregate models is a crucial link to the mesoscopic
mechanical analysis for fully-graded concrete. This study systematically presents the …

This paper investigates the influence of aggregate shape on the diffusivity of mortar in three
dimensions by random packing models of ellipsoidal and convex polyhedral particles. From …

Concrete is usually assumed to be a three-phase particulate composite composed of
aggregate, cement paste and interfacial transition zone (ITZ) around the aggregate. Due to …

Granular materials as typical soft matter, their transport properties play significant roles in
durability and service life in relevant practical engineering structures. Physico-mechanical …

Steel fiber reinforced concrete (SFRC) is composed of coarse aggregate particles, mortar
matrix, fibers, pores and microcracks from the viewpoint of meso-scale. To reflect the …

Particle size gradation is regarded as an effective method for overcoming the contradicting
requirements in three-dimensional printing (3DP). In present work, particle size gradation …
