“…Previous studies have found that river sand can be replaced in concrete and mortar with other various type of sand which include offshore sand. These studies provide evidence that offshore sand can be use as substituted for river sand in concrete and mortar [7][8][9][10][11]. The use of offshore sand in concrete was limited by the properties of the materials itself where the chloride content level is not suitable for concrete.…”

Alternative replacement for land aggregate is very important for island and coastal region where land aggregate resources is scarce, expensive and even unavailable for construction industries. For country that have limited sources of land aggregate, offshore sand is a potential choice of replacement for their construction industries. This research studied the production and usage of synthetic lightweight coarse aggregate produced using offshore sand (SYLCAG). SYLCAG was produced to replace coarse aggregate that normally use igneous rock for concrete production. It was produced with density of 1300 kg/m3 which is nearly 60% lighter than normal aggregate. This SYLCAG was used as a full replacement for coarse aggregate in concrete which then produced as a concrete with density almost 1900 kg/m3. The produced concrete did not have achieve the design strength of 25 MPa concrete using the standard concrete design. However, it still has the potential to be develop with higher design and later used as structural concrete.

“…A lower water-cement ratio was also used in seawater concrete because the salinity of the seawater was found to affect the overall performance of the concrete (Dhondy et al, 2021). In addition, the use of seawater would slightly reduce the slump and spread of cement paste generated in the concrete mixture compared to Da B et al, 2021;Li et al, 2021;Yue C et al, 2021;Dhondy et al, 2020;He X et al,2020;Yin et al, 2020;Parvizi et al, 2020;Chen G et al, 2020;Mansyur & Permana, 2020;Ma H et al, 2020;Gao et al, 2020;Soares et al, 2020;Adnan et al, 2020;Li, L.

Concrete is made from freshwater, cement, and aggregate and the only material shared with mankind, flora, and fauna is freshwater. One of the most concerning problems the world has been facing over the last few decades is the rising demand for freshwater due to the increasing global population and depleting source of freshwater by 2050. In Malaysia, the population is expected to rise from 32 million people in 2020 to 40.50 million people in 2050, which would correspondingly increase the demand for domestic houses, industrial areas, and other building construction as well as increase the overall usage of freshwater. The utilisation of seawater has been applied in constructing buildings and infrastructures since the time of the Roman Empire and the structures still survive for more than 2000 years against chemical attacks and underwater wave force. Given that seawater is considered an alternative mixing agent in concrete production, research on seawater-based concrete has continued to gain interest from the scientific community and undergone swift development. Therefore, the aim of this study was to present a systematic literature review on the recent development of concrete with seawater as the mixing agent and its effect on the physical and mechanical performance of the concrete. A four-stage investigation criterion was conducted for the data collection from the Scopus database, which includes the search parameter, identification, screening, and writing. The screening of the literature retrieved 53 articles, which were then classified based on the physical and mechanical properties of the concrete. Based on the review, the use of seawater as a single mixing agent reduced the physical and mechanical performance of the concrete. However, the incorporation of seawater with special chemical admixture, mineral admixture, and reinforcement with certain treatment resulted in a higher performance of the concrete. Finally, the review highlighted the various potential studies that can be performed to investigate the utilisation of seawater in the construction industry while achieving a sustainable solution to preserve the environment.

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.
