In the 1960s, SFRC was developed for reinforce physical properties of concrete. SFRC was in first use at the Ohio's truck terminal construction in 1971, is generally used in the engineering and construction industry, nowadays.
SFRC manufactured with hydrate cement, fine aggregate and discontinuous short steel fiber (25~80mm) is reinforcing material for improving physical properties of concrete's strength mechanical behavior.
The process of manufacturing SFRC is after mixing cement and fine aggregate, insert hydrate cement and disperse discontinuous short steel fiber in them. The feature of SFRC is the bellows.
Features of SFRC
- Increases moment capacity and cracking moment
- Increases the ductility
- Tensile strength increases
- Improves crack control
- Increases rigidity
- Preserves the structural integrity after beam exceed the ultimate load
