Metakaolin - Concrete Application

Concrete Application

Considered to have twice the reactivity of most other pozzolans, metakaolin is a valuable admixture for concrete/cement applications. Replacing portland cement with 8–20% (by weight) metakaolin produces a concrete mix, which exhibits favorable engineering properties, including: the filler effect, the acceleration of OPC hydration, and the pozzolanic reaction. The filler effect is immediate, while the effect of pozzolanic reaction occurs between 3 to 14 days.

Famous quotes containing the words concrete and/or application:

    freeways fifty lanes wide
    on a concrete continent
    spaced with bland billboards
    illustrating imbecile illusions of happiness
    Lawrence Ferlinghetti (b. 1919)

    We will not be imposed upon by this vast application of forces. We believe that most things will have to be accomplished still by the application called Industry. We are rather pleased, after all, to consider the small private, but both constant and accumulated, force which stands behind every spade in the field. This it is that makes the valleys shine, and the deserts really bloom.
    Henry David Thoreau (1817–1862)
