In this paper, the effect on cement clinker and cement quality was studied to prove the effect of reducing the sintering temperature of cement clinker as a mineralizer to recycle fluorine based semiconductor sludge, an industrial by-product. In addition, a verification study was conducted to compare the properties of clinker and cement at different temperatures when natural fluorite, previously used as a mineralizer, was used. As a result of the study, semiconductor sludge showed sufficient effectiveness as a mineralizer and could replace natural fluorite, an existing mineralizer.
