Cement Accelerator

Cement Accelerator is an admixture for the use in concrete, mortar, rendering or screeds. The addition of Cement Accelerator speeds the setting time and thus cure time starts earlier. This allows concrete to be placed in winter without the worry of frost damage .

Typical materials used for acceleration are Ca(NO3)2 and NaNO3. CaCl2 has been very popular, but due to its reinforcement corroding behaviour the use is not recommended any more and in many cases prohibited.

Famous quotes containing the word cement:

    Between married persons, the cement of friendship is by the laws supposed so strong as to abolish all division of possessions: and has often, in reality, the force ascribed to it.

    David Hume (1711–1776)
