description The invention relates to hardenable inorganic systems such as cements, plasters, ceramics or liquid silicates, usable for example in the building trade, construction industry or oil drilling industry. The invention more specifically relates to the insertion of carbonaceous nanofillers, such as carbon nanotubes, for reinforcing mechanical properties and improving such systems. The invention further relates to a method for producing a master mixture comprising at least one superplasticiser and carbonaceous nanofillers at a mass ratio of between 0.1 % and 25 %, preferably between 0.2 % and 20%, in relation to the total weight of the master mixture, and also to said master mixture thus obtained and to the use thereof in a hardenable inorganic system with a view to producing materials with improved properties. The invention applies to the construction industry, the building trade and the oil drilling industry. La présente invention concerne les systèmes inorganiques durcissables tels que les ciments, plâtres, céramiques ou silicates liquides, utilisables par exemple dans les domaines du bâtiment, de la construction ou de l'industrie des forages pétroliers. L'invention concerne plus particulièrement l'introduction de nanocharges carbonées, telles que des nanotubes de carbone, pour renforcer les propriétés mécaniques et améliorer de tels systèmes. L'invention porte sur un procédé de préparation d'un mélange-maître comprenant au moins un superplastifiant et des nanocharges carbonées à un taux massique compris entre 0,1% et 25%, de préférence entre 0,2% et 20%, par rapport au poids total du mélange-maître, le dit-mélange-maître ainsi obtenu et son utilisation dans un système inorganique durcissable en vue de préparer des matériaux de propriétés améliorées. L'invention s'applique aux domaines de la construction, du bâtiment, des forages pétroliers.
