Mechanical Properties of Rubberised Concrete Confined with Basalt-Fibre Textile-Reinforced Mortar Jackets

This paper presents an experimental investigation of the mechanical properties rubberised concrete confined with basalt-fibre textile-reinforced mortar (TRM) jackets. The main aim is to evaluate effectiveness TRM confinement scheme on cylindrical specimens by examining five different mixtures (rubber content ranging from 10.5% up 42% total aggregate volume), including a plain reference mixture. Unconfined and either one or two layers were subjected monotonic axial loading. results indicate decrease in compressive strength unconfined as rubber increased. stress–strain curves became smoother at peak increased, also exhibiting increased strain capacity post-peak. Rubberised exhibited less brittle failure than concrete, accompanied lateral dilation. Confinement strength, while enhanced performance terms toughness deformation compared concrete. Overall, it concluded that there promising potential for using TRM-confined applications ductility demands low environmental footprint specifications.
