Module I. Interaction of Reactive Particles

Research objectives are:

  • Determination of force-distance relationships on particles of various type, size, shape under consideration of hydration;
  • Quantification and modelling of morphological changes of binder and other fine particles as a result of hydration and/or alterations in the composition of the carrying fluid, e.g. by precipitation reactions and particle generation;
  • Derivation of structure-effect relationships for prediction of the influence of superplasticizers on the particle interaction;
  • Adapting numerical methods to simulate the particle interaction under consideration of electrostatic and steric effects.


Module II. Deformation Behavior of Fresh Concrete

Research objectives are:

  • Modelling of macroscopic flow behavior based on particle interactions;
  • Development of appropriate methods for rheology-based mix design;
  • Analysis of rheology of homogeneous and locally segregated suspensions;
  • Investigation of rheology of suspensions containing fibers.


Module III. Constitutive Relationships and Methods for Describing and Influencing Technological Processes

Research objectives are:

  • Study of pumping behavior of suspensions under special consideration of flow-induced segregation/particle migration;
  • Investigation of filling behavior of concrete in a formwork as an analogy to the open channel flow;
  • Analysis of placement by means of a nozzle, e.g. spaying or 3D printing;
  • Development of physically motivated, applicable test and prediction methods for rheological material behavior in specific processing scenarios.
