Many countries, including India, have been experiencing a lack of fresh and clean water for years. As concrete is one of the world's most widely produced materials, the water demand of the construction industry is always huge. The mixing water guidelines promote the use of fresh or potable water for concrete mixing. As a result, it is critical to investigate the viability of using wastewater in concrete production and in constructional activities too. This study investigates the potential use of grey water in concrete production. Grey water was considered as a potential alternative because of its widespread availability, perennial nature, and low contamination levels. In this investigation, cement and concrete specimens were prepared using grey water from three different sources. The attributes of these cement and concrete specimens were compared to those of cement and concrete specimens created with potable water, i.e. municipal tap water. The set time and compressive strengths of cement specimens prepared by grey water satisfy the water appropriateness criteria for mixing. Similarly, concrete specimens prepared by grey water either satisfy the criteria or show marginally better results than tap water specimens. Soaps, detergents, and surfactants in grey water may be responsible for the improved properties of concrete.
