Abstract
Additive for cement based composition comprising concrete, a mortar or a cement, comprises particles of iron (II) sulfate dry heptahydrate, which does not comprises more than 20 wt.% of the particles and having a granulometric size of 200 mu m, comprising at least 20 wt.% of iron (II) sulfate dry heptahydrate having granulometric distribution of 100-200 mu m. Independent claims are included for: (1) a cement based composition comprising concrete, mortar or cement, comprising the additive; and (2) a preparation of the composition comprising mixing the iron (II) sulfate dry heptahydrate particles with the cement.
