Exploring the Viability of Seawater in Concrete Mixing: A Sustainable Approach to Water Management in Morocco’s Construction Industry

Article Preview

Abstract:

Like many other nations, Morocco is grappling with escalating water stress, exacerbated by climate change, decreasing rainfall, and the increasing demand for water, particularly within the civil engineering sector. The growing reliance on concrete, driven by infrastructure development, has intensified pressure on already limited freshwater resources, presenting a significant challenge. In this context, the use of seawater in concrete mixing emerges as a promising alternative. While many studies explore ways to reduce freshwater consumption in civil engineering, few specifically address the use of seawater in concrete production. Seawater, which contains high levels of chloride and sulfate ions, can lead to the corrosion of steel reinforcements and potentially compromise the long-term durability of structures. Our research aims to explore this solution through a multi-phase approach. Initially, we will establish criteria for the acceptability of seawater as mixing water. Subsequently, we will conduct laboratory tests to assess the strength and durability of concrete made with seawater, comparing it with that produced using freshwater. Based on these findings, we will propose technical improvements to minimize the corrosive effects and enhance the viability of this approach. Ultimately, this study seeks to contribute to sustainable water management in the construction industry by alleviating pressure on freshwater resources, while supporting the growth and development of Morocco’s infrastructure.
