Researchers at [http://www.tuwien.ac.at/en/news/news_detail/article/8816/ TU Wien University] were able to develop a new system to create an inflatable concrete structure with much fewer resources than ever before.

The use of concrete stems back thousands of years to when ancient civilizations build magnificent structures with it. Its usefulness has withstood the test of time and has proven itself worthy as an integral component of modern-day construction.

Once hardened, concrete can resist compressive forces that reach and exceed 4000 PSI to 10,000 PSI, depending on the application and purpose. However, concrete can’t withstand flexion and altercation once it’s hardened. Therefore, it must be poured in its final shape. Current constructions involving concrete rely on wooden frames and other support systems to contain concrete as it cures. The process is excellent for constructing vertical structures, however, not all buildings are like that.

Curved concrete shells are impeccably strong and efficient, but, the process of making requires large amounts of resources and planning. Even the formwork that only contains the wet concrete needs excessive amounts of material to be built. While the structures are incredibly efficient, the construction process is not.

Good news is researchers at the TU Wien university now developed a method to inflate already hardened concrete into curved domes.

== Constructing domes by inflating hardened concrete ==

The process called “Pneumatic Forming of Hardened Concrete (PFHC)” was invented by Dr. Benjamin Kromoser and Prof. Johann Kollegger at the Institute of Structural Engineering. The idea is remarkably simple yet effective; place an air cushion underneath and support it with post-tensioning tendons to transform a flat concrete slab into a curved concrete shell. The process eliminates the need for excessive amounts of labor and material resulting in significant reductions in cost of constructions.

== How does it work? ==

The idea of the newly optimized construction method is relatively basic. Multiple wedge-shaped concrete slabs are cast on a flat surface. Once the concrete is cured an air cushion which is placed underneath is inflated. Post-tensioning tendons encircle the entire surface and add tension to prevent the slabs from sliding.

The construction of a prototype building with a 1:2 scale took just [http://www.tuwien.ac.at/en/news/news_detail/article/8816/ 2 hours]. It reached 2.90 meters. The design featured duel curves to prove the dexterity of the method.
