Buoycrete and Membrane Molding

: In this study, the authors present Buoycrete, a new material and work method invented by the company Boskalis. Buoycrete is a light-weight concrete that is able to float and does not dissolve in water. Buoycrete is based on a unique combination of different materials. This paper will start with an overview of concrete structures in combination with fabrics and will present the structural behavior, construction methods and applications of Buoycrete. It demonstrates that Buoycrete combined with fabric formwork creates new possibilities for a broad kind of applications, for instance, the realization of façade elements, shell structures and civil engineering.
