Abstract
The research aims to investigate the viability of employing polyester grout as a bonding agent for the splicing of reinforcement bars. 0.43 and 1 binder-to-filler ratio were examined. The process of splicing reinforcement bars under tension using a polyester grouted splice connector is elucidated. Through direct tension tests, the optimal mix design and required length of the splicing sleeve were identified. The findings indicate that the polyester grouted connector with a 0.43 binder-to-filler ratio performs satisfactorily for the splicing of tensile reinforcement bars. Specifically, a spiral length of 250 mm with an embedded length of 125 mm is demonstrated to achieve the full strength of the spliced bar.
