Description	With the aim to alternatively use fly ashes, including those already deposited, various factors have been studied as to their influence on the compressive strength evolution of geopolymers containing untreated black coal fly ashes with a high LOI. Geopolymers with a mechanical strength of up to 55 MPa were prepared after 90 days of hardening by manipulating some crucial parameters of the activation solution and the geopolymerization mixture. An influence of the replacement of up to 20 % of fly ash by various alumosilicate materials such as slag, kaoline, metakaoline, bolus and calcined bolus on the hardened geopolymers´ mechanical properties was also analysed.
