How Microsilica Improves Concrete Concrete Construction ...

1985-4-1  Addition of microsilica to a concrete mix alters the cement paste structure. The resulting paste contains more of the strong calcium-silicate hydrates and less of the weak and easily soluble calcium hydroxides than do ordinary cement pastes. Because the microsilica particles are so small they disperse among and separate the cement particles.
