Sustainable Alkali‐Activated Geopolymers From Red Mud and Ferroalloy Residues: Structure and Properties

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
TGA showed general thermal stability with gradual dehydration at T > 200°C. The physical properties changed progressively: apparent density decreased from 2.5 to 2.2 g/cm3 and water absorption reduced from 13% to 7% (90:10 to 70:30), indicating refined pore structures without defect porosity. This dual‐waste synergy advances circular economy principles,

In Situ Thermomechanical Evolution of Geopolymer‐Bonded Castables Containing Alternative Aluminosilicate Precursors

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT Geopolymer binders have emerged as promising alternatives to calcium aluminate cement (CAC) for refractory castables, although their thermomechanical behavior during heating remains poorly understood. This work investigates high‐alumina refractory castables bonded with geopolymers produced from metakaolin (MK), calcined kaolin (CC), and an ...

Degradation of Silicate Glass Used as Fine Aggregate in Concrete

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT A large body of literature has previously reported on the deleterious expansion which occurs if recycled soda lime silica (SLS) bottle glass is used as fine aggregate in concrete cast with ordinary Portland cement (OPC). It is theorized that this expansion is due to a propensity for the formation of a volume‐expanding alkali–silica reaction ...

Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2233-2257, September 2026.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...
