Designing an interlayer reinforcement solution for printable strain-hardening cement-based composites: Practical research on various bond improvement concepts

3D concrete printing is an additive manufacturing method that uses a printing robot to build 3D concrete elements. In the last decade, several 3D concrete printing techniques have been developed and extensive research has been conducted on suitable concrete mixes, the printing process and the material and mechanical properties of the finished...

Interfacial behavior of hybrid SHCC-Concrete beams with a joint at midspan

Strain Hardening Cementitious Composite (SHCC) is a new type of concrete that is able to control the crack-width in concrete structures. The application of this material in the tension zone of hybrid concrete structures is thus of interest in practice. The interfacial behavior for these hybrid structures is something that is of importance for...

Application of Strain Hardening Cementitious Composites for retrofitting unreinforced masonry

Starting from the late eighties induced seismic activity is present in the Northern part of the Netherlands. Cause of these earthquakes is the extraction of natural gas. In this region, most of the building stock comprises out of unreinforced masonry (URM) buildings. Multiple experimental campaigns are performed since 2014 to investigate the...

Flexural Behaviour of Reinforced Concrete Beams With a Layer of SHCC In The Tension Zone: Numerical Study By ATENA Model

Strain hardening cementitious composite is a new generation material with increased ductility and improved cracking behaviour as compared to traditionally used Normal Strength Concrete (NSC). An important charactersitic of SHCC is the ability of the fibers (2% PVA) in the composite mixture to bridge the cracks and there by preventing...
