Abstract: The invention relates to an analysis device comprising a main enclosure fitted with a secondary enclosure, a microprobe placed inside the main enclosure and fitted with an airlock and with a motion object, and a movable sample support that is movable from the secondary enclosure to the airlock and from the airlock to the motion object. Each of the airlock and the motion object includes a respective guide member for guiding the movable sample support and a respective sensor for detecting the presence of the movable sample support.

Abstract: 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 ?m 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.
