2020 12 23 Abstract. In this paper, the most important observations of the effect of seawater SW and/or sea sand SS on the properties of concrete are presented and critically reviewed. Concrete is responsible for about 9% of global annual industrial water and almost 70% of the extracted natural sands use. During last decades many researchers focused
2021 8 9 Seawater sea sand concrete SSSC refers to concrete prepared with seawater and/or sea sand instead of freshwater and/or river sand. It generally sets faster due to the exist of chloride but demonstrates slightly lower long term strength compared to ordinary concrete due to the effect of the sulfate or impurities 3, 4 .
The use of sea sand and seawater in concrete can provide sustainability to natural resources, while improving the mechanical properties of concrete. The corrosion of steel reinforcement is inevitable with the use of sea sand seawater concrete. Can you use sea sand in mortar? However, sea sand can not be directly applied to the production of
2021 2 21 Sea sand is one such alternative tried as fine aggregate in many countries. The present paper reviews the current status of utilization of sea sand as fine aggregate in concrete and its effect on
The application of sea sand is a systematic project, involving multiple links such as concrete raw materials, mix ratio, construction process supervision, and post maintenance. In order to prevent sea sand from being improperly used in the
The concrete samples were cured in natural marine conditions and atmospheric conditions and tested at 7 and 28 days. Sea sand–seawater concrete had a high early compressive strength at 7 days and remained slightly higher than conventional concrete at 28 days. The experimental procedure used all natural, unaltered, concrete constituents and
2022 7 11 After the sea sand is desalinated, it can also be used as construction sand and gravel, but the salt and chloride ions of the sea sand must be cleaned. With the progress of sea sand cleaning technology, the application range of sea sand will be wider. Japan strictly stipulates the limit value of chloride ion content per cubic meter of concrete.
2017 11 30 Effects of sea sand and/or seawater on the properties of concrete are summarised. Admixtures can enhance the performance of concrete with sea sand and/or seawater. Combination of sea sand seawater concrete with FRP leads to sustainable structures. Sea sand seawater concrete incorporating recycled coarse aggregate is attractive.
