3.high tempreture to 1600 degree
4.good activity indicators
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
