Influence of magnesia on sinter-crystallization, phase composition and flexural strength of sintered glass-ceramics from waste materials

Influence of Sintering Temperature on Mechanical Properties of Glass-Ceramics Produced with Windshield Waste

“…Because the consumption habits of the population have generated environmental problems such as the growth of landfills and depletion of natural resources [1,2], scientific research has been much requested regarding the recycling of discarded materials, for finding new utilities and generating value from the waste [2][3][4][5]. Glass, despite being recyclable, occupies large volumes in landfills [6].…”

“…is is due to the PVB (polyvinyl butyral) film, which exists between layers of glass, whose function is to protect the occupants, preventing the glass from shattering when breaking on impact [7]. Several studies have proposed the use of glass for the production of glass-ceramics, adding value and targeting a discarded material [2,[8][9][10]. e silicates, which are the basis of the glasses, can be used for the production of profitable products such as glass-ceramics [2].…”

When compared to glass, it has greater stability, durability, superior mechanical properties, resistance to thermal shock, low coefficients of thermal expansion, and fracture toughness [11,12].…”

Waste glass in civil engineering applications—A review

“…CWG, obtained from bottle waste, was used in the preparation of GFG. 133,[159][160][161][162][163][164] Toniolo et al 165 evaluated the potential of using CWG (soda lime) in fly ash-based geopolymers by conducting mechanical, microstructural, and leaching experiments. Concrete samples containing GFG showed no major change in workability compared to control samples.…”

“…Similarly, other studies have also demonstrated that CWG, coupled with other materials and at optimal conditions, could potentially be used in the manufacture of glass-ceramics. 133,[159][160][161][162][163][164] Toniolo et al 165 evaluated the potential of using CWG (soda lime) in fly ash-based geopolymers by conducting mechanical, microstructural, and leaching experiments. The ceramic mixture was prepared using aqueous NaOH solutions as alkali activation, while a liquid to solid ratio of 0.45 was set to achieve good workability.…”
