Etude par calorimetrie de l'hydratation du ciment Portland en presence de zinc
RésuméThe retarding effect of a zinc addition on the hydration of Portland cement is investigated by calorimetry. A small amount of zinc powder leads to a variation of the first peak maximum, an extension of the dormant period and a change of the second calorimetry peak. These effects are due to the formation of a primary zinc hydroxide and its conversion later on into crystalline zinc hydroxide. The evolution of the thermograms is also studied as a function of zinc percentage.
