Summary:Six glass compositions based on basaltic rocks and some industrial wastes, Batches were melted in an electric furnace at temperature 1400 °C for 2 h and then casted into rods and discs shapes. Many important techniques were used in the present study including X- ray fluorescence, thermal expansion, dielectric properties, indentation micro hardness, bending strength, density and chemical durability, The expansion coefficient in the temperature range 25–300 °C lies in the range between 48.78 to 59.76 × 10 −7 /°C and the temperatures of Tg started at 668.79 °C and ranging between 668.79–632.34 °C and Ts started at 737 °C and lies in the range and 737–711.6 °C respectively. The lower expansion glasses have higher transition and softening temperatures and vice versa. Bending strength and Vickers micro hardness show a gradual decrease from 118 to 56 MPa and 6120–4020 MPa respectively with increasing cement dust content. In the same time the density increases from 2.79 to 2.96 g/cm 3 by increasing cement dust content.
