This article evaluates the effects of seawater and sea sand on concrete performance and durability, and discusses the corrosion resistance of steel in seawater-mixed concretes. It also highlights the potential applications and challenges of seawater-mixed concretes in regions of water stress.
In order to directly apply seawater and sea sand in construction without desalination, a new type of circular concrete-filled steel tube (CFST) encased prefabricated seawater sea-sand...
This paper evaluates the feasibility and performance of using sea sand as a substitute for river sand in concrete. It discusses the material characteristics, workability, mechanical properties, durability, and challenges of …
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.
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 …
This study investigates the feasibility of establishing an environmentally sustainable ultra-high performance concrete from seawater and sea sand (SWSS-UHPC) which utilizes industrial byproducts (i.e., ground slag and silica fume) by partially substituting ordinary Portland cement (OPC).
The majority of studies show equivalent, if not better, results when sea sand and seawater are used in concrete, although some studies concluded otherwise. This paper investigates the variations in the chemical and physical properties of sea sand.
Strong evidence exists that a combination of mineral admixtures for the concrete and reinforcement with fiber reinforced polymer (FRP) can effectively solve the durability problem associated with the abundance of chloride ions in sea-sand seawater concrete (SSC).
Therefore, this study is expected to develop a feasible and cleaner strategy for the direct value-added utilization of sea sand and propose a novel design for the construction of high-performance CoAl 2 O 4 pigments with low cobalt consumption as well.
A paper in the Journal of Materials in Civil Engineering compares the chemical and physical properties of sea sand from nine locations and its use in concrete production. Sea sand–seawater concrete has a high early compressive strength and can be cured in natural marine conditions.
