In the present study, waste incineration fly ash samples, taken from a clinic and hazardous waste incineration and energy production plant in Turkey, were mixed with brick raw materials in 10%, 20%, 30%, 40% and 50% proportions. These samples were shaped, dried and fired. Subsequent to these phases drying and firing shrinkage, strength, water absorption, color, heavy metal contents (Ni, Cd, Fe, Cr, Cu, Ag) and TCLP analysis were conducted. Additionally, the samples were examined in terms of technical and environmental impacts and their possibility of utilizing in brick industry was explored. In connection with the findings of the present study, and concerning the results of the strength tests as well, it can be claimed that adding fly ash to brick production process in 10% and 20% proportions is convincingly an appropriate process. Moreover, concerning the results of the present study it can be claimed that utilization of maximum 20 % waste incineration fly ashes as additive material in brick industry might be an appropriate stabilization process.
