Microsilica, also known as Silica fume, is a
byproduct of producing silicon metal or ferrosilicon alloys.
Microsilica consists primarily of amorphous (non crystalline)
silicon dioxide (SiO2). The individual particles are extremely
small, approximately 1 (**0th) the size of an average cement
particle. Because of its fine particles, large surface area, and
the high SiO2 content, silica fume is a very reactive pozzolan when
used in concrete.
It has been found that Microsilica improves compressive strength, bond strength, and abrasion resistance; reduces permeability; and therefore helps in protecting Key advantages of triple blend concrete are: Reduced sensitivity of concrete to the effects of insufficient curing Very low chloride permeability throughout the service-life of concrete, even at early ages High compressive strength and durability Life-cycle cost is lower because of reduced maintenance and longer lifereinforcing steel from corrosion. |
