Investigating the Impacts of Slag Contents on the Thermal Characteristics of Foam Glasses

Abstract:

The scourge of tonnes of waste generation from municipal, industrial, and medical facilities, among other sources, is a serious concern, significantly the increase in disposal through landfills, incineration, and others, which may pose further health and environmental challenges. In our work, we intend to study the characteristics of foam glass made from hazardous waste incinerator slags (HWIS) and waste bottle glass with 1.5%wt SiC used as foaming agents. Varying percentages (10%wt, 20%wt, 25%wt) of slags were sintered with waste bottles (88.5%wt, 78.5%wt, 73.5%wt). The increase in the height of the green samples with temperature rise, properties of the produced foam glass-like thermal conductivity (0.04-0.135W/mK), effusivity, water absorption (31.93%-98.67%), and compressive strength (3.92-5.61MPa) were checked as well. Our results gave great possibilities for the applicability of slags as secondary raw materials for foam glass production with good thermal insulating characteristics and other physical properties relevant to the expectations of construction materials.
