Blended red brick powder/metakaolin geopolymers
Original language description
The production of red-clay hollow bricks belongs to the sources of ceramic waste which is related to the current trend of utilization of the thin joint technology. Since the current technologies of hollow brick production do not enable to provide sufficiently smooth and even surfaces, the brick blocks have to be ground generating waste red brick powder. This product contains reactive aluminosilicate phases that can be used as precursors for the geopolymer binder. Geopolymers based on the blends of red brick powder and metakaolin having three different ratios of aluminosilicate components and two different alkaline activators were prepared. Substitution of metakaolin by red brick reduces the viscosity of a fresh mixture and diminishes the thixotropic behaviour of metakaolin geopolymer. Although the mechanical properties of pure red brick geopolymer are quite poor, the blends containing up to 50% of red brick show similar mechanical properties as pure metakaolin geopolymer.
