The ceramic tile industry produces waste ceramic tile powder during the final polishing process. Ceramic tile waste powder can contaminate soil, weather. The use of ceramic waste powder as an alternative material in concrete will have a positive environmental impact. After conducting research and studies by previous researchers, materials are prepared for laboratory compressive strength of concrete mixing designs. After mixing methods, sampling is done from each of them. Ordinary concrete samples are known as control samples, and also concrete with ۵, ۱۰ and ۱۵% percent of ceramic tile powder is mixed and made. The specimens are made for ۷ and ۴۲-day olds, and their compressive strength test is performed. Using the results of the compressive strength test results, it can be said that, in general, up to ۷ days of age, all designs containing recycled soil powder have a better compressive strength growth trend than the control design. Still, this growth trend is more significant at ۴۲ days of age and older. It is for ۷ days.
