The stability of fresh concrete should be properly considered to ensure the quality of building
engineering while requiring its high flowability. The poor fresh state stability is detrimental to …

Alkali-activated binders for concrete composites are emerging as the available low-
embodied-carbon alternatives to ordinary Portland cement (OPC). Despite decades of …

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 …

The geometry of the attached mortar present in recycled concrete aggregates influences the
behaviour of recycled aggregate concrete, since this mortar is porous, rough and tends to …

This work focuses on elastic modulus of two main constituents of cement based materials:
portlandite (CH) and Calcium Silicates Hydrates (CSH). At nano-scale, the single CH crystal …

The mesostructure of concrete plays a very important role in the process of initiation and
propagation of cracks. Microcracks tend to start in the Interfacial Transition Zone (ITZ) and …

High-frequency vibration helps to improve the compactness of concrete, but also causes the
settlement of coarse aggregates (CAs) and then affects the durability of hardened concrete …

This paper proposes formulae for refined models that account for wall effects when
modelling the geometric mesostructure of concrete. The wall effect should be taken into …

Concrete is a heterogeneous material whose constituents (eg, hydrated cement paste,
aggregate etc.) ranges from a characteristic length-scale of a few nanometres to metre …

Mesoscale modelling is a promising tool to analyse the phenomenological causes of
mechanical failure of recycled aggregate concrete (RAC). Most mesoscale models of RAC …
