Concrete is the most widely used construction material worldwide, and its production consumes more than two million tons of fresh water annually—a resource that accounts for only 3% of the planet’s available water, compared to 97% of seawater. Furthermore, 75% of freshwater consumption occurs in areas experiencing extreme water scarcity. In Peru, the distribution of water resources is unequal due to the geographic location of water sources relative to population centers, with the coastal region being the most affected since it has the lowest water availability and the highest concentration of inhabitants. This research evaluated, through laboratory testing, the mechanical properties of fresh and hardened concrete mixed with seawater, as a 100% replacement of potable water, and incorporating 30% to 50% blast furnace slag (BFS) and 5% to 15% metakaolin (MK) across eight sample types that varied these three components. The mixture containing seawater, 40% BFS, and 10% MK showed lower workability and reduced compressive strength at 28 days; however, it most closely resembled the control sample, suggesting its potential for future applications.
