Water is an essential resource for humans and a key component in the creation of concrete. However, the availability of this vital resource is being strained by the lack of fresh water brought on by population increase, climate change, and rising pollution. The concrete industry is increasingly using unusual waters, such as treated wastewater, brackish water, and industrial water, in response to the scarcity of fresh water. Although using these waters has benefits for the ecology and economy, there are concerns about how it may affect the quality of concrete. Despite the importance of the subject, there is a lack of scientific articles synthesizing the effects of all water characteristics and their interactions on concrete properties. With this in mind, this study aims to investigate the influence of the main characteristics on the strength, consistency and durability of concrete, using a qualitative approach based on a detailed synthesis of the literature. Our analysis of various water sources reveals that several key parameters in the mixing water significantly impact concrete. These include: pH - low pH leads to reinforcement corrosion, concrete cracking, and strength loss. High pH can degrade mechanical strength and cause setting and hardening issues. Chlorides promote reinforcement corrosion, cracking, loss of adhesion, and reduced mechanical properties. Sulfates contribute to swelling, cracking, strength loss, and aesthetic deterioration. Finally, suspended matter decreases mechanical strength, increases porosity, reduces durability, and hinders workability. Beyond their individual influences, the interaction between these different parameters is of particular importance, especially between ph and other parameters, as well as between chlorides and sulfates.
