CA 2265648

A method for preparing concrete or mortar in which a mixture of a hydraulic binder, aggregates, water, and colloidal silica is prepared. The relative standard deviation of the particle size distribution by numbers of the colloidal silica is at least about 30 %. The invention also relates to concrete or mortar obtainable by the method.

Ce procédé de préparation de béton ou de mortier consiste à préparer un mélange d'un liant hydraulique, d'agrégats, d'eau et de silice colloïdale. Les particules de silice colloïdale présentent un écart type de distribution granulométrique se situant au moins aux alentours de 30 %. L'invention concerne également le béton ou le mortier que l'on peut obtenir à l'aide de ce procédé.
