Crystallisation of glasses based on the diopside anorthite eutectic system containing increasing amounts (0-30 wt%) of orthodase was studied. Waste by-pass cement dust formed during the manufacturing of Portland Cement. was used in the glass batches in amounts ranging between 25-37 wt% of the batch constituents. Due to its veri-fine nature it causes air pollution which affects negatively the health of the citizens, animals, plants and land. Depending on the composition batches were melted in the range 1300-1400degreesC The glasses obtained and their corresponding heat treated specimens were examined by D TA. x-ray, SEM and optical microscopy. It has been found that increasing the content of the orthoclase phase in the glasses results in an increased bulk crystallinity when treated at 1100degreesC for 3 h. This effect was accompanied v a change in the texture of the glass ceramic specimens from coarse to fine grained Microcline phase was formed with diopside and anorthite when the percentage of the nominal orthoclase reaches 20 or 30 mol%. The present application of by-pass cement dust waste may pare the way to get rid of it with a friendly environmental method through the manufacturing of glass ceramic products.
