Influence of steel reinforced grout configuration, and reinforcement ratio on the flexural performance of strengthened continuous RC beams

Structural Concrete, EarlyView.
Abstract The field of reinforced concrete (RC) strengthening continues to evolve as the construction industry seeks cost‐effective and sustainable alternatives to structural replacement. This study, therefore, aimed to comprehensively investigate the pioneering application of steel‐reinforced grout (SRG) for strengthening large‐scale, 3.5‐meter‐long ...

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 ...
