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.

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.

Confinement model for circular concrete columns transversely reinforced with GFRP spirals and hoops

Results in Engineering, 2023
In many applications, bars made of Glass-Fiber-Reinforced-Polymer (GFRP) have successfully replaced steel rebars and become a practical substitute for shear and flexural reinforcement in reinforced concrete (RC) members.

Investigation of the effect of fibers on bond properties between self-consolidating concrete and GFRP rebars [PDF]

, 2011
This study evaluated the effect of different fiber types (macro steel fibers, macro PP-fibers and micro PP-fibers) on the bond properties between self-consolidating concrete matrix and glass fiber-reinforced polymer (GFRP) rebars.

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 ...

A Study of the Shear Behavior of Concrete Beams with Synthetic Fibers Reinforced with Glass and Basalt Fiber-Reinforced Polymer Bars

Buildings
The use of synthetic materials with high corrosion resistance in a concrete matrix yields structures that are more durable and suitable for use in aggressive environments, eliminating the need for frequent maintenance.

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 ...
