The paper presents the assessment of metakaolin-slag-potassium-silicate geopolymer mixtures containing concrete and fired clay aggregates from Construction and Demolition Waste (CDW). An extensive characterization was carried out from a mechanical and physical standpoint, aimed at exploring their potential as a building material and their suitability for exploitation at industrial level. Based on the obtained experimental results, geopolymers with CDW showed promising properties for use in building elements even with 50% of aggregates and more, although further aspects need dedicated investigations.
