    Abstract: The invention aims at addressing the issue consisting in providing a GGBS-based binder or a mortar or concrete composition including said GGBS-based binder, which is not prone to develop an undesirable colour as the setting and the hardening occur. Hence, the invention pertains to a GGBS-based binder comprising at least one GGBS; at least one oxidation agent OA of the GGBS sulphur compounds, particularly of the species S 3 - of said GGBS sulphur compounds. The method for the preparation of the GGBS-based binder, the mortar or concrete composition and its preparation method, the wet formulation made from said composition and its preparation, the making hardened articles from this wet composition, and the use of at least one oxidation agent OA for discolouring GGBS-based concrete/mortar composition, are other objects of the invention.

    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.
