A comparison of ceramic and carbon‐based reductants for vitrification of low‐activity waste

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Sucrose is the current baseline additive at the Hanford Waste Treatment and Immobilization Plant in Washington to control foaming during waste feed to glass transitions and the redox state of the glass melt. Alternative reductants are being investigated to alleviate strain on effluent treatment from toxic acetonitrile production from ...

Using boron as a tracer reveals how surface precipitates inhibit silicate dissolution in hyperalkaline solutions during alkali–silica reaction

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Silicate dissolution under hyperalkaline conditions is a key process that affects the evolution of alkali–silica reaction (ASR) in concrete. In these environments, dissolution may involve multiple overlapping processes—including ion adsorption on reactive sites, transport of dissolved species, and the formation of alteration layers.

Investigation on the Potential of Bacteria‐Coated Jute Fiber for Enhancing Mechanical Properties and Self‐Healing Capabilities in Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Concrete faces challenges such as low tensile strength, susceptibility to cracking, and limited self‐healing capabilities. To address these issues, natural fibers have gained attention as reinforcements due to their high specific strength, stiffness, biodegradability, and renewability.

Investigating the Mechanical and Microstructural Properties With Machine Learning Optimization of Recycled Eco‐Friendly PET Modified Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Over the past decades, studies have demonstrated the effectiveness of polyethylene (PE) and PE terephthalate (PET) as an alternative to aggregates in enhancing concrete performance. This research aims to predict the compressive strength (CS) of PE and PET‐incorporated concrete by evaluating the influence of key factors, including cement content, PET ...

Evolution of Unconfined Compressive Strength and Microstructural Properties of Geopolymers From Blended Waste Concrete Powder and Metakaolin

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The use of waste concrete powder (WCP) in geopolymer synthesis offers a sustainable method for recycling construction and demolition waste (CDW). However, its low reactivity and high calcium content frequently result in geopolymers with inadequate mechanical strength.

Fayalite-Based Geopolymer Foam

Ceramics
The present work is the first study exploring the potential of geopolymer foams based on fayalite slag, an industrial by-product, as the primary precursor, for lightweight and fireproof construction applications. The research involved the synthesis and characterization of geopolymer foams with varying water to solid ratio, followed by testing their ...
