Ce este fumul de silice?
Fum de silice, cunoscut și sub numele de Microsilica, is an ultrafine pozzolanic material collected during the production of silicon metal and ferrosilicon alloys.
Due to its extremely fine particle size and high amorphous silicon dioxide (Sio₂) conţinut, silica fume significantly improves the strength, densitate, durabilitate, and chemical resistance of concrete.
Typical applications include:
- High-strength concrete
- Ultra-high-performance concrete (UHPC)
- Bridge and highway construction
- Marine structures
- Industrial flooring
- Shotcret
- Oil well cementing
- Piese refractare
