This project aims at bridging knowledge gaps for alkali-activated material (AAMs), by apply
experimental and theoretical methods to AAMs, which have allowed to decipher the
multiscale physical properties of ordinary Portland cement (OPC) systems. The envisaged
research will provide in-depth understanding on the fundamental mechanism of the
solidification processes (reaction mechanisms and kinetics, phase formations and binder
structure), on rheological properties, on volume stability (shrinkage and cracking potential),
and on the evolution of mechanical properties (setting, strength, and viscoelastic behaviour).
This will be coupled with predictive multiscale modelling. By interlinking the complementary
expertise of the involved partners, the limits of current research capabilities will be pushed
forward and the challenging AAM behaviour will become comprehensible. This way, new
methods for developing “microstructurally designed concrete” might arise. In addition,
because of the complex nature of the AAMs, there is also a need for new or extended
fundamental techniques in many fields of expertise. Therefore, this project will formulate
challenging technique developments. The insights obtained in this project will not be
beneficial for AAMs only, they might provide a scientific basis for designing environmentally
friendly binders with properties as favourable or even superior to the ones of classical cement
paste.
