Hydro-abrasive erosion of concrete incorporating ground blast-furnace slag and ground basaltic pumice

open access: yesConstruction and Building Materials, 2009
Abstract In this research work, an attempt has been made to find the suitability of the ground blast-furnace slag (GBS) and ground basaltic pumice (GBP) as a possible substitute for conventional crushed fine aggregate. The main purpose of this investigation is to determine the hydro-abrasive erosion (HAE) characteristics of concrete with GBS and GBP ...

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

open access: yesBoreas, Volume 55, Issue 1, Page 231-257, January 2026.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

Shear Behavior and Shear‐Flow Coupling Mechanisms of Red‐Clay‐Infilled Joints Under High Water Pressure

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Rock joints are considered as a discontinuity between two continuous media. The presence of infilled joints influences the mechanical and hydraulic properties of joint rock. Understanding these properties is critical for assessing underground excavation safety, slope stability, and water inrush risk.
