Preparation and characterization of lightweight glass–ceramics based on industrial wastes
Source abstract
Abstract
Lightweight glass–ceramics based on bypass cement dust and glass waste were prepared successfully through a powder technology method. Five batches with 20 to 50% cement bypass (with regard to the glass waste) were mixed and compressed by uniaxial dry pressing into discs then applied into direct sintering at 1000 °C for 1 h. To investigate the properties of the obtained glass-ceramics, different methods were applied, including DSC, XRD, SEM, investigation of thermal expansion coefficient, bending strength and microhardness. XRD showed that the major crystalline phase is wollastonite. SEM showed that open and closed pores increased gradually until reaching its optimum value for sample 35 bp (35% bypass + 65% glass waste). The density and porosity range for the obtained glass-ceramics were 1.3–2.0 g/cm3 and 31–56%, respectively.
