Sinai basaltic rocks and bypass cement dusts from the Misr Beni Suef plant in Egypt were examined for use in the preparation of technical glass-ceramic materials. Cement kiln dust generated during the manufacturing of Portland cement was used in glass batches, in amounts ranging between 10-50% of the batch constituents. Batches were melted and then cast into rod and disc shapes and subjected to heat treatments. Techniques used in the present study included differential thermal analysis, x-ray diffraction, microhardness indentation, and assessment of bending strength, water absorption, density and chemical durability. The obtained glass-ceramic materials were mainly composed of diopside, gehlenite, magnetite and anorthite with a uniform crystal size of less than 150 nm as shown by SEM. The final materials possessed high values of mechanical properties, hardnesses ranging from 4•1-6•8 GPa, bending strengths ranging from 75-135 MPa, with high chemical durability and zero water absorption, which would allow them to be used in many applications, such as building materials, ceramic tiles, etc.
