Abstract: The invention relates to a slag-based binder or a mortar or concrete composition including said slag-based binder. The purpose of the invention is to propose a binder which is an attractive substitute to OPC- based compositions,environmentally friendly,cheap and competitive, more acceptable than OPC-based compositions, with respect to the sanitary and safety issues, which gives rise to wet formulations with appropriate rheological properties, i.e stable rheology during a the usual setting time ( e.g . one to several -3-hours)required by the users of said wet formulation, without increasing the W/B ratio and jeopardizing the mechanical properties of the hardened material obtained from this wet formulation. To fulfil this purpose, the invention is a Slag-based binder comprising: A. at least one slag; A'. at least one CO 3 -containing mineral powder; B. optionally at least one co-binder different from binder A. and from CO 3 powder A'.; C. at least one activator of the water/slag reaction; D. at least one chelatant and/or at least one source of chelatant, said chelatant being preferably a scale inhibitor; E. and, optionally, at least one superplasticizer different from the chelatant D. The invention also pertains to a kitto make the binder, a dry concrete or mortarcomprising the binder and aggregates, a method for the preparation of a wet formulation (binder/water or concrete-mortar/water), and method of manufacturing buildings or civil engineering works or elements thereof, coatings, fillers, screeds, tiles adhesives and/or internal or external insulation systems, from the wet formulation.
