Journal of Microscopy, EarlyView.Abstract Iron‐sulphide‐bearing aggregates can compromise concrete durability when reactive sulphide phases, particularly pyrrhotite (Fe1–xS), oxidise and contribute to internal sulphate attack, cracking, and premature deterioration. Existing aggregate assessment methods, including bulk sulphur measurements, petrographic examination, oxygen consumption ...

Influence of Pulverized Lightweight Pumice Fine Aggregate on the Cement Mortar’s Dry Shrinkage
Journal of EngineeringThe use of lightweight aggregates in cement concrete manufacturing solves the issue of drying shrinkage over the concrete's life span; nevertheless, the use of artificial lightweight sand may increase this issue in the cement mortar. This research looks

Meteoritics &Planetary Science, EarlyView.Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Earthquake Spectra, Volume 42, Issue 4, November 2026.Modern confined masonry (CM) construction consists of masonry walls confined by reinforced concrete (RC) tie‐columns and tie‐beams. When built correctly, CM buildings have shown good performance in earthquake's shaking. Even though CM construction has been practised for almost a century in some Latin American countries, its use and standardisation are ...
