Influence of Treated Grey Water on Properties of Concrete Using Silica Fume as Admixture

- Concrete is also one of the most water-intensive industries. Water is undoubtedly vital in civil engineering, and there are no suitable substitutes now. Chemical water limits for concrete indicate that non-potable water can be used as mixing water, according to various concrete standards. Grey water, for example, might be repurposed to alleviate pressure on freshwater supplies. Traditional concrete production mainly relies on freshwater resources for mixing and curing, resulting in water scarcity in many areas. The construction sector may drastically cut its water usage and environmental footprint by substituting treated Grey water for some freshwater. Following proper treatment and purification, Grey water can partially replace fresh water in concrete mixtures without harming the material’s performance, durability, or strength. This study aims to determine how the use of Grey water affects the quality of concrete. A M 40 concrete mix was blended with silica fume to increase the strength of the concrete.
