“…Whereas the alkali-activated slag (AAS) system has rapid setting time and relatively lower workability than OPC [6]. In order to conquer these limitations, alkaliactivated fly ash-slag (AAFS) blended system has recently attracted increasing attention due to its potential ability to achieve superior engineering properties under ambient curing condition [7][8][9].…”

“…Similar to other fibre materials, basalt fibres integrated with a resin matrix were also employed in innovative structures for strengthening or retrofitting. In most studies of FRP bar-reinforced concrete structures, attention has been given to the static properties [13][14][15][16]. Mahroug et al [13] compared the test results and design codes through experiments on six slabs reinforced with BFRP bars and found that the compounded shear-deflection failure led to a lower failure moment than the codes estimated.…”

In addition, the bond durability in aggressive environments [14], the corrosion resistance, and the mechanical behaviour of structural components reinforced with BFRP rods [13,15,16] have been analysed and reported by other investigators.…”

An innovative cellular concrete procured with sat-SAP (superabsorbent polymer) is introduced. Combined with BFRP bars, this concrete may play a role as protective structures in marine applications. Eight BFRP-reinforced cellular concrete slabs (BSs) and three steel-reinforced normal concrete slabs (SPs) are exposed to simulated blast loadings in a shock tube device. Low-modulus cellular concrete and BFRP bars cause BSs to exhibit distinctive behaviours compared to those of SPs. BSs, which are more flexible at the same reinforcement ratio, have more intensive vibrations and larger deformations compared to SPs under various blast loadings. In addition to the porous structure of cellular concrete, BSs demonstrate better wave-attenuating and energy-absorbing abilities. More severe damage such as cracks, deflections, and breaches is observed for BSs. In the current research, a comprehensively superior blast resistance can be achieved through improving reinforcement ratio to promote serviceability.

“…These research studies reported that FRP bar reinforced concrete columns exhibited lower axial load capacity compared to equivalent steel RC columns. The FRP bars were effective in resisting axial loads and hence the contribution of FRP bars should be adequately accounted for in the axial load capacity of FRP bar reinforced concrete columns [19][20][21][22][23][24][25]. The flexural behavior of FRP bar reinforced concrete beams was extensively investigated.…”

The axial and flexural behaviors of Concrete Filled Carbon Fiber Reinforced Polymer Tube (CFRP-CFFT) columns have received significant research attention in the last two decades. One of the most attractive advantages of Carbon FRP (CFRP) tube is the high confinement which results in substantial increase in peak axial and flexural loads and deformations. Despite large research efforts, the behavior of CFRP-CFFT with and without CFRP reinforcing bars under different applied axial load eccentricity has not yet been adequately investigated. This study investigates the experimental and analytical axial-flexural (P−M) interactions of CFRP-CFFT columns with and without CFRP reinforcing bars. A total of 12 specimens of 204-205 mm outer diameter and 800-812 mm height were tested under concentric axial load, 25 mm and 50 mm eccentric axial loads and four-point load. The effectiveness of CFRP reinforcement (tube and bar) was observed to be reduced with the increase in the applied axial load eccentricity. Analytical P−M interactions were constructed using available FRP confined concrete design codes which matched well with the experimental P−M interactions. The parametric study showed that the actual confinement ratio, orientation of fibers and CFRP bar reinforcement ratio have significant influences on P−M interactions of CFRP-CFFT specimens.
