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.

The paper can be found at: https://www.researchgate.net/publication/319208857_Self-Sealing_Cementit...

RILEM Multi-scale Modelling Course for Concrete (MMC2)

The RILEM Multi-scale Modelling Course for Concrete (MMC2) provides the opportunity for participants to become familiar with modelling cementitious materials at four different levels of detail. Different ways of schematization and numerical approaches are considered to simulate the chemical, physical and mechanical behaviour of cementitious materials.
