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

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.
