Effect of Recycled Fine Aggregate Replacement Ratio on the Fresh State, Mechanical, and Water Absorption Properties of Self- Compacting Mortar

This study demonstrates that while increasing the replacement of natural fine aggregates with recycled aggregates in self-compacting mortar progressively reduces flowability, compressive strength, and durability due to the recycled material's higher porosity and rougher texture, moderate replacement levels between 25% and 50% offer a sustainable balance of workability and mechanical performance.

Reconciling carbon footprints and mechanical properties in laser powder bed fusion with 316L stainless steel

This study demonstrates that strategically optimizing laser powder bed fusion parameters for 316L stainless steel, such as increasing layer thickness and utilizing nitrogen shielding gas, can simultaneously reduce carbon footprints by up to 24% while maintaining high part density and low porosity, challenging the notion that sustainability and mechanical quality must be traded off against each other.

A CFD-based critical-velocity threshold framework for flood resilience assessment of vulnerable timber covered bridges

This study proposes a cross-disciplinary CFD-based framework for assessing flood resilience in vulnerable timber covered bridges, demonstrating through the case of Taixin Bridge how its historical irrigation system creates a "functional symbiosis" that maintains critical velocities below overturning thresholds even under extreme hydrological conditions.

Effects of Loading Frequency on the Dynamic Response and Pore Structure of Silty Clay under Repeated High-Amplitude Loading

This study utilizes cyclic triaxial and Mercury intrusion porosimetry tests to demonstrate that higher loading frequencies reduce accumulated plastic strain and energy dissipation in silty clay by limiting the time available for pore-structure rearrangement, which primarily transforms macro-pores into meso-pores while increasing macro-pore heterogeneity.
