Expanded perlite and bio-based residues for circular low-carbon cementitious materials: a systematic review

The transition to circular and low-carbon construction requires materials that combine resource efficiency, thermal performance, mechanical adequacy, and waste valorization. This review synthesizes 139 studies published between 2010 and 2026 on expanded-perlite and bio-based ceme...

Multiscale Analysis of Depositional Architecture and Diagenetic Evolution in the Cretaceous Shoreface‐to‐Shelf Sandstones, Lower Indus Basin, Pakistan

ABSTRACT Understanding reservoir heterogeneity in siliciclastic systems requires integrated analysis across multiple scales. This study investigates the Early Cretaceous Lower Goru Formation in the Lower Indus Basin using a multiscale integrated approach that combines seismic str...
