Abstract |
|
|
| Large amounts of powder of limestone waste, cement kiln dust and phosphate are accumulating all over Egypt every year and disposal of these tailings is needed. Recycling of the wastes into glassy material is one from the best ways for eliminating their hazardous impact on the people and environment. Glasses based on these tailings were prepared by conventional melt-quenching method. The composition dependence of the elastic properties of these glasses was discussed in association with the effects of adding SiO2. The addition of SiO2 was expected to produce significant changes such as an increase in density, ultrasonic velocities and elastic moduli. |
