什么是二氧化硅烟?
微硅粉, 也称为微硅粉, 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 (二氧化硅) 内容, silica fume significantly improves the strength, 密度, 耐用性, and chemical resistance of concrete.
Typical applications include:
- 高强混凝土
- Ultra-high-performance concrete (超高性能计算)
- Bridge and highway construction
- Marine structures
- 工业地板
- 喷射混凝土
- Oil well cementing
- 难治性铸造物
