Originální abstrakt

Waste brick powder represents an easily available supplementary cementitious material that can contribute to the enhanced properties of lime plasters and concretes. Furthermore, the prerequisite properties of the brick powder enable its application in alkali activated materials. In this study, brick powder was used for production of binary alkali activated binders with metakaolin, slag or fly ash. Brick powder based geopolymers were tested for their mechanical properties, porosity and microstructure; flow properties of the fresh geopolymers were evaluated by rheometric measurements. In accordance with the results, brick powder could be a suitable precursor for blended binders with metakaolin and slag. These samples exhibited good mechanical properties and microstructure characteristics. The combination with fly ash was less applicable due to a rapid setting, hardening retarder used in these binders caused significant deterioration of the mechanical properties and massive efflorescence formation.
