Steel–Mortar and Flexural Mortar–Mortar Bond Strengths of Metakaolin‐Based Geopolymer

Engineering Reports, Volume 7, Issue 11, November 2025.
Metakaolin‐based geopolymer mortar demonstrated significantly higher interfacial bond strength than cement mortar across both mortar–mortar and steel–mortar testing, with performance influenced by interface transition zone (ITZ) roughness and curing age.

Effect of GFRP rebars and polypropylene fibers on flexural strength in high-performance concrete beams with glass powder and microsilica

Case Studies in Construction Materials, 2023
Considering the benefits of GFRP rebars and their lighter weight compared to steel rebars and the sustainability of polypropylene fibers, GFRP rebars and polypropylene fibers are investigated as sustainable materials replacements for steel rebars in high-

Short‐length mechanical bond anchorage for reinforcement bars made of FRP: Experimental and numerical investigations

Structural Concrete, Volume 26, Issue 1, Page 821-836, February 2025.
Abstract The availability of fiber‐reinforced polymers (FRP) as an alternative for conventional steel reinforcement in concrete construction is increasing. To widen the scope of application, for example, in the case of prestressing, and to improve the bond behavior at the bar ends, end anchorages need to be considered.

Poststrengthening Remote Monitoring in Practice: A Case Study of RC Structure Renovation

Journal of Engineering, Volume 2025, Issue 1, 2025.
Reinforced concrete (RC) structures are widespread globally, requiring systematic monitoring and proactive maintenance due to ageing, evolving demands and environmental exposure. Prolonging the service life of existing RC structures to meet modern requirements promotes sustainability by reducing waste, conserving resources and minimising environmental ...

Novel Splice Method of Reinforced Concrete Beams Without Web Reinforcement Subjected to Pure Torsional Loading

Journal of Engineering, Volume 2025, Issue 1, 2025.
This work examines the performance of no web reinforced concrete beams with novel spliced longitudinal steel bars and enhanced by wrapped CFRP sheet subjected to pure torque. The spliced bars were of insufficient length to show the substandard state and were treated with a new method of enhancing the splice region by wrapping CFRP sheet transversely ...

A Novel Structural Assessment Technique to Prevent Damaged FRP-Wrapped Concrete Bridge Piers from Collapse [PDF]

, 2009
Repairing deteriorated concrete bridge piers using externally wrapped fiber reinforced polymer (FRP) composites have been proven as an effective approach. This technique has also been applied to low-rise building structures.
