Hydratation de l'aluminate monocalcique. II : Role du broyage.

Abstract : The comminution of monocalcium aluminate depends both on the grinding process and the composition of the solid : an "Aurec" vibrating crushing mill is more acting than a planetary ball mill. The subsequent reactivity of the solid versus water is more enhanced for "super-stoichiometric" aluminate (C/A=1.04) than for "sub-stoichiometric" one. Moreover, a connection between both the "balling fitness" of the solid and its activation during grinding was pointed out, what let suppose that entities responsible of the balling phenomenon take a prominent part in the hydration kinetics and can be considered as aluminate vacancies precedently identified.
