SHOTCRETE
Shotcrete is, in effect, an edition of a cast-in-place concrete wall. Rather than placing concrete into forms, nevertheless, a fresh mix is sprayed onto wall panels that have been erected in the form of the building. 



A nozzle-man applies concrete from a pressurized hose to include the reinforcement and build up the wall thickness, forming structural shapes that include walls, roofs, floors, and other assemblies. 


This material has also been called “gunite” in reference to the nozzle or “gun” used to shoot matter at the form face. 


Any surface appropriate for accepting fresh concrete can be used: steel, wood, and polystyrene are common. 


Finishes are frequently applied directly to the concrete while it is still wet.

SELF COMPACTING CONCRETE
Self-compacting concrete (SCC) is considered by several experts to be the greatest breakthrough in concrete technology for many decades due to the enhanced performance and working environment. 



It all started around 1988 at Tokyo University with Prof. Okamura and his students, among others Ozawa and Maekawa, as they established the fundamental description of SCC. 


Before that, numerous cases of application were known in which the concrete did not need external consolidation to obtain essential compaction and could consequently be considered as SCC, without being defined as such.
