“…Particularly promising is the possibility of its utilization as a component for the production of cement or new building elements (recycling). Polish power plants and combined heat and power plants produce approximately 20 Mt of CBPs from coal every year, including fly ash and slag [6]. Utilizing such waste also brings economic benefits, such as avoiding landfilling.…”

This paper presents the results of sorption tests against selected gaseous pollutants SO2, CO2 and H2O on geopolymer materials obtained from high-calcium fly ash from lignite power generation. In the synthesis process, activation of geopolymer materials was carried out using KOH and NaOH. It was found that the activating agent significantly affects the porous structure of the samples. The sorption experiments conducted for the KOH-activated sample showed high SO2 adsorption efficiency, almost ten times higher than against CO2. The results demonstrate the possibility of utilizing fly ash obtained from the lignite energy processing sector for the synthesis of geopolymers with potential application of the materials as functional plastering compounds.
