Pneumatic formwork construction

Concrete as a construction material has an especially high resistance to compression. Concrete shells with a geometry optimized in a way such that primarily compressive forces arise are accordingly structures that can transmit great loads and span large areas with a minimum of material. The expenditure for formwork, however, currently leads to high costs, making their implementation in most cases inefficient.

At the Institute of Structural Engineering of the Vienna Technical University, a new concrete forming system with the name Pneumatic Forming of Hardened Concrete (PFHC) has been developed...
