Etude de l'hydratation du ciment en presence de zinc influence de la teneur en gypse
Cement paste hydration is delayed by zinc which changes fundamental hydrates forming a thin layer of amorphous zinc hydroxide around anhydrous particles. Evolution of this compound depends on pore solution composition of cement paste. In this paper, the authors study the influence of the amount of sulfate. Samples of cement paste used are prepared with adding to one clinker increasing amounts of gypsum. With small proportions of sulfate, C3A hydration is accelerated by zinc. On the contrary, if SO3 is more than 2.5%, zinc delays C3A hydration. C3S hydration is always delayed and with 4% in SO3, setting does not occur.
