Description
Silica fume is used in concrete. When it is used in concrete, it acts as a filler and as a cementitious material. The small silica fume particles fill spaces between cement particles and between the cement past matrix and aggregate particles. The silica fume also combines with calcium hydroxide to form additional calcium hydrate through the pozzolanic reaction. Both of these actions result in a denser, stronger and less permeable material.

Application : 10% to 15% High strength structural columns
10% Flatwork
8% to 10% High durability / Low permeability such as bridge decks or parking structures
8% to 15% by weight of cement but as an addition not replacement


Silica Fume has been used as an addition to concrete up to 15 percent by weight of cement, although the normal proportion is 7 to 10 percent. With an addition of 15 percent, the potential exists for very strong, brittle concrete. It increases the water demand in a concrete mix; however, dosage rates of less than 5 percent will not typically require a water reducer. High replacement rates will require the use of a high range water reducer.

Function of adding Silica Fume(microsilica) :
• Increase durability

• Reduces concrete permeability

• Improves resistance to corrosion

• Shotcrete - lower rebound
