CONSTRUCTION MATERIAL MIXTURE, A METHOD FOR PRODUCING SAME, AND USE THEREOF

摘要

A construction material mixture used as a concrete additive contains a puzzolanic substrate and a photocatalyst. The puzzolanic substrate and the photocatalyst are available in the form of a dry mixture. The construction material mixture is a cement free dry mixture, wherein the photocatalyst has a primary particle size of between 2 nm and 100 nm. The puzzolanic substrate consists of at least 90 weight % of fly ash with a grain size of between 0.1 μm and 1 mm. The substrate and the photocatalyst are available completely mixed so that the photocatalyst is at least partially distributed on the surface of the substrate.
