We featured "Concrete Curtains" earlier but what does concrete have to do with lightweight architecture? Researchers at the Kassel University are exploring new synergies of constructions and materials - including a combination of membrane constructions and concrete.
To create this lightweight building out of concrete, a flexible skin with an embedded membrane structure is inflated with air and filled up with a special concrete mixture such as UHPC (Ultra High Performance Concrete). Once the substance is hardened a solid concrete skeleton allows the building to be finished from the inside.
Instant housing such as these concrete-based Concrete Canvas Shelters are made to save lives in refugee camps. If Kassel's research works out well, building a solid house might become as quick and easy and as blowing up a big balloon?
