“…Other anecdotal evidence of the significant research on this topic includes a) large, funded proposals to investigate seawater-mixed concrete in Europe, Qatar, and Hong Kong, including the authors of this publication as investigators (SEACON, NPRP 9-110-2-052, etc. ), and b) a special issue of the journal Advances in Civil Engineering Materials on Concrete Using Seawater and Salt-Contaminated Aggregates which was Guest Edited by the corresponding author of this publication, and c) five review papers published on seawater and sea sand concrete between 2017 and 2021 [13][14][15][16][17].…”

“…In spite of five existing review papers on this topic, this current publication is novel because three review papers focus on seawater and sea sand concrete [13,14,16], one focuses on FRP [15], and only one focuses on seawater-mixed concrete [17]. Xiao et al [13] present a comprehensive discussion of the more engineering aspects of seawater-mixed concrete, and topics such as hydration, microstructure, etc.…”

“…Multiple studies have shown that seawater accelerates the early-age hydration of cement [11,[16][17][18][19][20][21][22][23][24][25][26]. Some studies show that the induction period is unaffected, while others show a shortening in the duration of the induction period.…”

“…Continued efforts have been made accordingly to address the shortage of natural resources, such as geopolymer concrete [ 3 , 4 ] and recycled aggregates [ 5 , 6 ]. Recently, an innovative concept of seawater sea sand recycled aggregate concrete has been proposed by many researchers [ 7 , 8 , 9 , 10 , 11 ], in which seawater, sea sand, and recycled aggregates are applied collectively as replacements for fresh water, river sand, and rock fragments. These more sustainable alternatives have been certified as successful substitutes.…”

In response to resource shortage and carbon dioxide emissions, an innovative type of sustainable concrete containing LC3, seawater, sea sand, and surface-treated recycled aggregates is proposed in this study to replace traditional concrete. To understand the bond properties between the sustainable concrete and CFRP bars, an investigation was conducted on the bond behavior between sand-coated CFRP bars and advanced sustainable concrete. Pull-out tests were carried out to reveal the failure mechanisms and performance of this bond behavior. The results showed that the slip increased monotonically along with the increase in confinement. The bond strength increased up to approximately 15 MPa, and the critical ratio of C/D was reached. The critical ratio approached 3.5 for the Portland cement groups, while the ratio was determined as approximately 4.5 when LC3 was introduced. When the proportion of LC3 reached 50%, there was a reduction in bond strength. A multisegmented modified bond–slip model was developed to describe the four-stage bond behavior. In terms of bond strength and slip, the proposed advanced concrete exhibited almost identical bond behavior to other types of concrete.

The application of CFRP bar and seawater sea-sand concrete (SSSC) in construction can overcome the shortcomings in conventional reinforced concrete, such as corrosion induced by carbonation and chloride ingress. In this study, the bond-slip behavior between an SSSC cube and CFRP bar has been investigated, and different CFRP bar surface shapes have been considered. A total of 27 specimens (9 groups) were fabricated for a pull-out test, where three types of CFRP bar with different surface shapes were used: smooth regular bars, double-wrapped bars and ribbed bars. Bond strength, bond-slip curve, and failure mode have been presented and discussed. FE models have been constructed and validated by experimental results. The effect of concrete compressive strength and relative area of ribs on bond strength has been studied through numerical simulations. It is found that the bond strength increased with concrete compressive strength, and the ribbed bar had significantly higher bond strength than the smooth regular bar. Pull-out failure was observed when the cover-depth-to-bar-diameter ratio was no less than 4 and, otherwise, splitting failure occurred. In addition, a simple formula has been proposed to approximately evaluate the bond strength between an SSSC cube and CFRP bar and validated by experimental results, and analytical expressions for different bond-slip curves have also been developed.
