A large amount of fly ash is accumulating in Kangal Thermal Power Plant in our country. Fly ash produced in this plant is abandoned to the landfills and causes certain serious environmental problems and health hazards. Waste glass also constitutes some problems. The most of non-recyclable glass is sent to landfill that is not an environment-friendly solution. Therefore, there is a strong need to be utilized it in building sector because it is not biodegradable. In this study, masonry blocks were produced by using fly ash, lime and waste glass powder. Blocks were cured for periods of 24, 48, 72 and 96 hours at 70 degrees C. The compressive and flexural strengths, water absorption, sorptivity and density values of blocks were determined. It was found that curing time and amounts of additional materials that were lime and waste glass powder in the block were directly effective on the results. The results obtained showed that block could be produced by using these waste materials.
