In order to reduce cement consumption, which is one of the significant factors in man-made carbon dioxide emissions, studies are being conducted on issues such as alternative building materials. Replacing cement with fly ash is at the forefront of cement reduction studies. However, the use of fly ash with a high sulfate content in structural elements is limited by European and American standards. Here the production of pumice stones used as wall material is discussed. Pumice blocks were made by replacing the cement in pumice blocks with high sulfate fly ash. High sulfate fly ash increased the late strength of pumice blocks by about 13%. In addition, as a result of a brief economic analysis for Türkiye, it turned out that wall costs could be reduced by up to 8% thanks to the replacement of fly ash. The mechanical and physical tests performed on the blocks produced concluded that the cement could be replaced with fly ash with a high sulfate content of up to 30%.
