【 摘 要 】

This study was conducted to investigate the effect of Carbon Fibre Reinforced Polymer (CFRP) on the stress responses of ferrocement slabs. For this purpose, a total of eight ferrocement slabs of size 500 × 500 × 18 mm were cast and tested. The major variables studied in this investigation included the number of CFRP strips and their configurations. Structural performance parameters used for comparisons included load-deflection curves, ultimate load and corresponding deflection at failure, failure modes, and crack patterns. That the inclusion of CFRP strips for strengthening ferrocement slabs can significantly improve their resistance may be concluded from these experiments. The increases ranged between 26 and 74% compared with the control specimen. Furthermore, an increase in the stiffness of the ferrocement slabs at all stages of loading, and a consequent reduction in the deflection at corresponding loads, was observed in specimens with CFRP compared to the control specimen. This decrease in maximum deflection was about 23.5 to 53.6% compared with the unstrengthened slab.
