I am of the firm opinion that fibre reinforced self compacting concrete(FRSCC) with hybrid fibres shall be the ideal concrete for form structures and it will be interesting to know of any such structures built, before we conclusively recommend to adapt only the FRSCC for such structures in view of the extrordinary characteristics of this compound material.
Probably International Association for Shell & Spatial Structures(IASS) is the right forum to deliberate and specify the use of FRSCC for all Shell structures.
Thank you Ms.Aria for the inputs.
The sites given by you refer to Ultra High Performance Concrete(UHPC) & Reinforcement Solutions for Geometrically Complex Concrete Structures respectively. The studies and details of UHPC made available in the site refers to Reactive Powder Concrete(RPC), which I happened to make brief studies as a Research Topic initially before switching over my studies to Fibre Reinforced Self Compacting Concrete(FRSCC).
While RPC is almost a replacement for steel due to its very high strenghs and can be used in complex applications, the prohibitive cost and production difficulties makes this compound reserve for very critical and judicious applications, whereas FRSCC can be easily produced and do not require any consolidation and hence, the geometrically complex form structures can easily be cast without fear of damages/accidents to scaffolding structures due to non-requirement of vibro-compaction.
