In the present study, stress-stain behaviour of confined concrete made with basalt fibre reinforced polymer bars (BFRP) were taken up. The stress-strain was studied for mixes steel rebars and BFRP rebars. confinement given in form hoops cylinders, 3 (0.8%), 4 (1.1%), 5 (1.3%) 6 (1.6%). addition fibres along enhanced compressive strength, indicating further effect concrete. It is observed that h...

This study investigates the influences of three types locally available low-cost Fiber Reinforced Polymers (FRP) wraps and two concrete mix designs on axial behavior FRP confined concrete. The experimental program comprised four unconfined (control), glass Matt Strand (GFRP-MS) concrete, Rowing (GFRP-R) carbon (CFRP) specimens with a diameter 150 mm height 300 tested under compression. were pre...

The need for concrete with ‘super’ strength and ductility greater sustainability has been answered by the existence of ultra-high-performance (UHPC) fiber-reinforced (UHPFRC). Over last decades, UHPFRC implemented in actual structures, as well used to retrofit structural elements, including columns. However, use UHPC confinement strengthen normal columns is still limited. Therefore, this resear...

Well-defined carbon polyhedrons with faceted morphologies and hollow internal structures made of self-organized multi-walled carbon nanotubes have been fabricated by gas phase catalytic CVD inside microchannels, of which the confined space is critical for the formation of polyhedral structures with hexagonal, heptagonal and octagonal cross-sections that show superhydrophobic properties, with th...
