Microsilica Concrete
Microsilica Concrete. Microsilica is used in concrete. Microsilica 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.
