Use of High Sulfate Fly Ash in Pumice Blocks

Abstract

In the world facing a reality called climate change, issues such as reducing cement production, which is one of the protagonists of human-induced carbon dioxide emissions, and the production of alternative building materials, continue to be popular. Herein, pumice block production, which is used as a masonry material, is discussed. Pumice blocks were produced by replacing the cement used as a binder in the production of pumice blocks with high sulfate fly ash. With the mechanical and physical tests performed on the blocks produced, it was concluded that up to 30% of the cement could be replaced by high sulfate fly ash. In addition, as a result of a short economic analysis for Türkiye, it has been suggested that the cost of masonry can be reduced by up to 8%.
