Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...

Carbon Dioxide Uptake and Storage in Construction Materials: Mechanisms, Theoretical Capacity, and Global Potential

cScience, Volume 2, Issue 2, June 2026.
ABSTRACT The construction sector constitutes a major source of global carbon dioxide emissions, and cement production contributes substantially via fuel combustion and limestone decomposition. These challenges have encouraged the incorporation of carbon dioxide into construction materials through mineralization.

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Co‐Calcination of Silicate or Aluminosilicate Network of Clay and Non‐Clay Minerals With NaOH: Physicochemical Insights

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Effects of co‐calcination with alkali hydroxide on pure clay minerals (kaolinite, montmorillonite) and typical impure minerals (quartz, feldspar) are presented. Co‐calcining montmorillonite and quartz with sodium hydroxide improves their reactivity. Co‐calcining kaolinite with sodium hydroxide reduces its reactivity.

Pozzolanic activity of argentine vitreous breccia containing mordenite

Materiales de Construccion, 2020
A vitreous breccia with variable amount of mordenite was studied for its use as pozzolan. The raw material was characterized by optical and scanning electron microscopy (SEM), X-ray diffraction (XRD), and the zeolite content was estimated by the ...
