With the increase in industrialization, the amount of fly ash (FA), which is one of the industrial solid wastes causing environmental and human health problems, is increasing day by day. Waste valorization and reuse methods need to be developed for this waste ash. The construction industry is the main sector where it is used. In this study, it is aimed to evaluate the usability of industrial FA in the production of economical and useful building panels and to determine their physical-mechanical properties. FA supplied from İsken Sugözü Thermal Power Plant (ISTPP), ordinary Portland cement (OPC) supplied from ÇİMSA Cement Industry and Trade Inc., molding plaster (MP) and lime are the materials of this study. Particle distribution curves were determined by using laser scattering method for FA ISTPP . In this study, compressive and flexural strengths, water absorption, bulk density and porosity as mechanical and physical tests were made in the building panels having the combination of FA ISTPP +cement FA ISTPP +MP and FA ISTPP +lime in contribution ratios of 10, 30, 50, 70 and 90%FA ISTPP . The results of the experiments show that the highest compressive strengths values in 7 and 28 days found in the building panels having combination of 90% cement+10% FA ISTPP are 57.30 and 64.20 MPa, respectively. It was determined that the value-added building panels could be produced from FA ISTPP , an industrial solid waste, in the appropriate proportions of cement contribution.
