Multi-scale modelling course for concrete, Delft, Netherlands

Dear all,

Our section at the Delft University of Technology is organizing this years' edition of the "Multi-scale modelling Course for Concrete" between 21-24 of August in Delft, the Netherlands. The course considers concrete on scales ranging from nanometre (MD) to micrometre (cement paste hydration) and metre (complete structure) scale. The course is organized by TU Delft, with lecturers also from TU Darmsdat and Tecnalia, Spain. Prospective participants can find more information on:

Experimentally validated multi-scale modelling scheme of deformation and fracture of cement paste

Our group has recently published a new paper on simulations and modelling of mechanical properties of cement paste in Cement and Concrete Research, the leading journal in the field. 

Abstract:

Bio-based Self-healing Mortar: An Experimental and Numerical Study

Recent years have seen a lot of development in the field of self-healing materials. Our group at Delft University is working (for more than a decade) on development of self-healing concrete which uses bacterial spores embedded in the matrix to "heal" cracks. In recent years, the focus has shifted on development of numerical models as tools for development of these materials.

Experimental and numerical study of crack behaviour for capsule-based self-healing cementitious materials

Dear all,

Our group at Delft University is developing self-healing concrete for over a decade. Recently, they have published a combined experimental and modeling study related to designing these materials.

Self-Sealing Cementitious Materials by Using Water-Swelling Rubber Particles

Dear all,

Our group has recently published a paper on self-sealing of cementitious materials by using water-swelling rubber particles as admixtures. This is the first time that such an approach was developed to increase the water-tightness of cracks and therefore enhance the concrete durability.
