Abstract
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 insertion of carbonaceous nanofillers, such as carbon nanotubes, for reinforcing mechanical properties and improving such systems. A method for producing a master mixture including 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 disclosure applies to the construction industry, the building trade and the oil drilling industry.
