Impact of the water-curing time on the carbonation initiation period of high-volume limestone powder concrete [PDF]

Građevinski Materijali i Konstrukcije
The high-volume limestone powder concrete (HVLPC) is one of the potential CO 2 mitigation strategies within ready-mixed concrete sector. As with other low-clinker concretes, its durability related properties, carbonation resistance especially, could ...

Tuning Redox Dynamics in Cu‐Based Electrocatalysts: Effect of Secondary Metals

Advanced Functional Materials, EarlyView.
Advanced analysis of operando X‐ray absorption spectroscopy data reveals that secondary metals affect the redox processes in Cu‐based catalysts for electrocatalytic CO2 reduction. This influences the amount of oxides formed under pulsed reaction conditions and the distribution of reaction products.

Concrete affected by multi-modal exposure of CO2 curing and alkali silica reaction (ASR)

Discover Concrete and Cement
In the past decades the ability to create durable, and sustainable concrete has largely been achievable thanks to the relative abundance, and regional availability of supplementary cementing materials (SCMs). SCMs are widely recognized to reduce and even

Performance of Cementitious Materials Subjected to Low CO₂ Concentration Accelerated Carbonation Curing and Further Hydration

Buildings
Excessive carbonation curing can impair later-age properties; therefore, determining an appropriate carbonation duration is critical for practical low-CO2 utilization.

Hierarchical Primary‐Secondary Coordination Synchronizes Ion Flux and Sulfur Redox in Solid Polymer Electrolytes

Advanced Functional Materials, EarlyView.
Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...

Accelerated Carbonation Curing as a Means of Reducing Carbon Dioxide Emissions

, 2021
Globally, carbon dioxide concentration has immensely increased post the industrial revolution. With more greenhouse gases generated from human activities, more radiation is being absorbed by the Earth’s atmosphere, causing an increase in global temperature. The phenomenon is referred to as the greenhouse gas effect.

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Improvement effect of carbonation curing on the performance of lightweight calcium carbide slag cement-based materials under the coupled action of sulfate attack and dry-wet cycling

Case Studies in Construction Materials
To promote sustainable utilization of calcium carbide slag (CS) and rice husk while enhancing CO₂ sequestration, lightweight materials were previously developed by incorporating foam and raw rice husk into a carbonation curing calcium carbide slag cement-
