Pulverulent mortar composition comprising a mineral binder, an inert material in the form of aggregate capable of being agglomerated in aqueous phase by means of said binder, and 0.2 to 1% of a fluid additive comprising 25 to 100% of a linear or branched, saturated or unsaturated hydrocarbon compound (i) which is liquid at room temperature and which includes one or more &#x2014;COO&#x2014; ester groups, the total weight of which, relative to the molar mass of said compound, is between 20 and 50%. Use for preparing an adhesive mortar for fixing ceramic tiles.

Pulverulent mortar composition having improved adhesion

Disclosed are a hydraulic binder composition containing at least 50% by weight of ground granulated blast furnace slag and a system for activating the slag, the system containing at least calcium sulphate, at least one product chosen from a source of Portland clinker and lime, at least one aluminum derivative and at least one alkali metal or alkaline earth metal salt; containing a ready-to-mix building material composition comprising such a hydraulic binder and aggregates of inert material capable of being agglomerated in the presence of an aqueous phase; and a process for employing the ready-to-mix composition containing a stage of mixing the said composition with water for the purpose of the preparation of a building material, such as a concrete or mortar, and in particular an adhesive mortar, pointing mortar or levelling mortar or coating.
