Silica Fume: Pros - Cons & Its Effect on the Properties of ...
The silica fume concrete is more cohesive and less susceptible to segregation as compared to the ordinary concrete. As the amount of silica fume content increases, the concrete may seem to become sticky. In the silica fume concrete, the workability is lost with time and loss is directly proportional to the increase in the amount of condensed ...

Silica Fume| Concrete Construction Magazine
Silica fume, a by-product in the manufacture of ferrosilicon and also of silicon metal, is a very efficient pozzolanic material, though there are some problems associated with its use in concrete. The use of silica fume in concrete should be limited to specialized applications that can take full advantage of its unique properties.

Silica fume - Wikipedia
Applications Concrete. Because of its extreme fineness and high silica content, silica fume is a very effective pozzolanic material. Standard specifications for silica fume used in cementitious mixtures are ASTM C1240, EN 13263. Silica fume is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance.

Advance Construction Material – Micro Silica In Concrete
Micro silica, also known as Silica fume is fine amorphous silica. Added to concrete at around 30kg/m3 it changes the rheology and reacts with the cement hydration products to dramatically improve concrete strengths, durability and impermeability, allowing concrete to be used in ways never before possible.

What are the disadvantages of silica fume in concrete? - Quora
The addition of silica fume can also influence the color of both plastic and hardened concrete. Typically, silica fume concrete is darker gray than conventional concrete and it can become almost black, in some cases. This difference is a direct result of the color and amount of the silica fume used.

Benefits of Using Silica Fume in Concrete | Civil Engineer
Silica Fume reduces the permeability of the concrete. Water and chemicals ingress are thus reduced. The ability of high C3A cement to complex with chlorides results in the formation of insoluble compound, able to reduce the mobility of free chloride ion to the reinforcement-concrete surface.
