Geopolymer from ISF zinc slag reported for first time. Effect of milling atmosphere is distinctly evident on properties. Calorimetry results shows effect of altered reactivity on geopolymerization. ISF zinc slag geopolymer samples have compressive strength (after 28 days) > 70 MPa. TCLP studies show zinc slag geopolymer is environment friendly.

Cryogenic grinding produces particles of rubber with a finer surface than produced by ambient grinding. The granules of grinded rubber produced by ambient grinding are soft ( Kim et al., 2018 ). Like plastic waste, rubber waste, due to its low density, is also appropriate for use as lightweight aggregate.

Zinc melts at about 790 °F and boils to vapor at about 1650 °F. Therefore zinc oxide vapor can absolutely be created by grinding galvanized steel without "melting" the base metal in a welding operation or otherwise. The likelihood of producing the zinc vapor in significant quantities goes up with reduced thickness of the workpiece.

Indeed, zinc ions bind aggregate-prone proteins such as amyloid-β, tau, FUS/TLS, and superoxide dismutase 1 (SOD1), and often promote their aggregation 22.
