Introduction of silica fume :
Silica fume, also called as micro silica, silica dust, which is a byproduct of producing silicon metal or ferrosilicon alloys. Silica fume consists primarily of amorphous (noncrystalline) silicon dioxide (SiO2). Because of its fine particles, large surface area, and the high SiO2 content, silica fume is a very reactive pozzolan when used in concrete.
Densified Silica Fume is the most revolutionary concrete additive to have been developed in recent times: The use of densified silica fume offers concrete manufacturers significant opportunities to substantially improve the strength, durability, finish and economy of their products and concrete applications also it can be used with conventional
Feature of silica fume:
1. Fine granularity.
2. Narrow particle distribution.
3. Large surface area.
4. Excellent suspension performance.
5. Reinforcement of good performance.
