“…Very limited researchers have investigated the effect of confinement on high strength SWSSC having a control compressive strength of more than 60 MPa. Few researchers have also investigated the confinement of fibre reinforced SWSSC by using BFRP needles [45] and structural polypropylene fibres (SPF) [61]. BFRP needles with a length of 100 mm and a diameter of 10 mm were produced from cutting BFRP bar scraps and were used to replace coarse aggregates.…”

“…However, the compressive performance of control SWSSC made with BFRP needles was inferior due to the poor interlocking as they were cylindrical in shape. Structural polypropylene fibres used by Sun et al [61] were 30 mm long and had a diameter of 0.6 mm. With increasing amount of SPF from 4 to 6 kg/m 3 , the compressive performance of control concrete increased from 19.4% to 36.8%.…”

The environmental concerns raised by the over-exploitation of fresh water and river sand have driven researchers to explore seawater sea sand concrete (SWSSC) as a substitute for conventional concrete in structural columns. With numerous investigations on this in the past, there is a need to systematically classify and comprehensively understand the response of confined SWSSC columns to promote their usage as structural columns. Consequently, the objective of this review is to summarise and analyse the experimental work conducted so far on confined SWSSC under different compressive loadings. Confined SWSSC columns are classified into five confinement schemes based on the cross-section of the specimens: single-skin, single-skin multilayered, single-skin with additional reinforcement, double-skin, and double-tube-confined SWSSC columns. Based on the findings of the reviewed studies, it can be concluded that the compressive strength and the ductility of the SWSSC can be enhanced through confinement, with effectiveness majorly depending on the material and geometrical properties of the confinement providing material. The existing research work on SWSSC confinement lays out a strong base for future investigations in this area, which will eventually facilitate the acceptance of SWSSC as structural columns, especially for coastal and marine infrastructure.
