Abstract

L'invention concerne un mélange de matériau sous forme d'additif pour béton, comprenant un support pouzzolanique et un photocatalyseur. Le support pouzzolanique et le photocatalyseur se présentent sous forme de mélange sec. Il s'agit d'un mélange sec exempt de ciment, le photocatalyseur présentant une taille de particules primaires comprise entre 2 nm et 100 nm et le support pouzzolanique étant constitué d'au moins 90 pour-cent en poids de cendre volante d'une granulométrie comprise entre 0,1 mum und 1 mm. Le support et le photocatalyseur sont intimement mélangés de telle manière que le photocatalyseur est réparti au moins en partie sur la surface du support. Ce mélange de matériau améliore l'ouvrabilité d'un béton par comparaison à l'utilisation d'autres supports pouzzolaniques pour le catalyseur.
