Details
This research proposes using natural hemp fiber-reinforced ropes (FRR) to strengthen recycled aggregate concrete columns, offering a cost-effective alternative to synthetic FRPs. Experimental results show significant improvements in compressive strength and ductility.
This research suggested natural hemp fiber-reinforced ropes (FRR) polymer usage to reinforce recycled aggregate square concrete columns that contain fired-clay solid brick aggregates in order to reduce the high costs associated with synthetic fiber-reinforced polymers (FRPs). Key aspects include:
- Experimental Setup: A total of 24 square concrete columns were tested under monotonic axial compression.
- Variables: Strength of unconfined concrete and the number of FRR layers.
- Key Findings: Strengthened specimens showed increased compressive strength and ductility. Specimens with the smallest unconfined strength saw the largest improvements, with compressive strength and strain enhanced by up to 181% and 564%, respectively.
- Modeling: The study investigated analytical stress–strain models and employed neural networks to predict compressive strength, demonstrating close agreement with experimental results.
Objective
