Membrane Gas Separation for CO2 Capture From Flue Gas: Materials, Modules, Processes, and Application Prospects for Coal‐Fired Power Plant Retrofitting

Safety Science and Technology, EarlyView.
This review systematically covers the full CO₂ flue gas membrane separation chain, finding it cuts energy use by ∼30% versus amine methods, yet faces stability and cost hurdles for large‐scale application. ABSTRACT As global climate change becomes increasingly severe, carbon capture, utilization, and storage (CCUS) technologies have emerged as a ...

Influence of calcination temperature on the durability of metakaolin concrete and limitations of conventional testing methods

Structural Concrete, EarlyView.
Abstract Incorporating metakaolin (MK) as a partial cement replacement offers a viable pathway to reduce carbon emissions while improving concrete performance. However, its durability behavior remains inconsistent, and the applicability of durability test methods to MK‐based concrete is not well established.

A probabilistic framework for modeling chloride‐induced corrosion and related load‐deformation behaviour of reinforced concrete

Structural Concrete, EarlyView.
Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

Structural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

Structural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...

Quantifying the embodied‐carbon premium of RC transfer beams via automated design

Structural Concrete, EarlyView.
Abstract Transfer structures in reinforced concrete (RC) buildings enable architectural flexibility but often increase material use and embodied carbon. This study introduces an automated framework to quantify the embodied‐carbon premium associated with such systems. For each parametric configuration, two equivalent RC frames—one regular and one with a

Development and characterization of eco‐friendly fire‐resistant 3D‐printable concrete utilizing recycled nickel slag

Structural Concrete, EarlyView.
Abstract This study investigates the utilization of industrial nickel slag waste to develop eco‐friendly fire‐resistant 3D concrete printing (3DCP). The benefits of waste nickel slag are bifold: it serves as a partial replacement, reducing carbon‐intensive cement and enhances fire resistance.

Decoupling sustainability and performance: How government infrastructure projects in Australia fare on strategic environmental commitments

Australian Journal of Public Administration, EarlyView.
Abstract Australian government organisations are pivotal in helping to meet the United Nations sustainable development goals. Yet while these organisations promote sustainability in their strategic plans, they struggle to embed these same commitments into their own infrastructure and construction projects. This study examines this persistent disconnect
