A dry binder premix includes, in mass proportions: Portland clinker having a Blaine specific surface area comprised from 4500 to 9500 cm2/g, the minimum quantity of the clinker by mass percentage relative to the total mass of the premix being determined according to: [-6.10-3×BSSk]+75, in which BSSk is the Blaine specific surface area of the clinker given in cm2/g; fly ash; an alkali sulphate; one source of SO3; complementary materials having a Dv90 less than or equal to 200 mum selected from limestone powders, calcined shale, metakaolins, siliceous fillers, silica powders, pozzolans, slags, fly ash and mixtures thereof. A quantity of clinker+the quantity of fly ash is greater than or equal to 75% by mass percentage relative to the total mass of the premix and a total quantity of clinker in the premix is less than 60% by mass percentage relative to the total mass of the premix.
