On The Role Of Soft Inclusions On The Fracture Behaviour Of Cement Paste

Soft inclusions, such as capsules and other particulate admixtures are increasingly being used in cementitious materials for functional purposes (i.e. self-healing and self-sensing of concrete). Yet, their influence on the fracture behaviour of the material is sometimes overlooked and requires in-depth study for the optimization of mechanical...

Creating Strain Hardening Cementitious Composites (SHCCS) Through Use Of Additively Manufactured Polymeric Meshes As Reinforcement

Strain hardening cementitious composites are a class of cementitious materials showing metal-like (i.e. pseudo-plastic) behavior in tension due to their multiple cracking ability. This is commonly achieved through use of fiber reinforcement (such as PVA) or, similarly, textile reinforcement (TRC). Increasing the ductility is important in...

Cracking of SHCC due to reinforcement corrosion

Reinforcement corrosion is the most important deterioration mechanism affecting reinforced concrete infrastructures. After corrosion starts, expansive pressures are exerted onto the surrounding concrete, causing cracking and spalling of the cover concrete. The amount of cover cracking can possibly be reduced by using strain hardening...
