Durability Assessment of Grey Water in Performance of Concrete Using Admixture

When Portland cement, a necessary component of concrete, is manufactured, 2.5 billion tons of greenhouse gases, including carbon dioxide, are released into the atmosphere. Despite its undeniable relevance, there are yet no effective substitutes for water in the field of civil engineering. If specific conditions are met, water that is not fit for human consumption can be utilized as mixing water. This rule is applied to concrete using chemical water limitations. Grey water recycling is one possible technique to reduce the demand for freshwater resources. The primary purpose of this research project is to determine how adding grey water to the concrete production process affects the end product's quality. Prior to mixing, silica fume and filtered grey water were added to an M-40 concrete mix to improve its durability. The following phase entails determining the extent to which treated grey water and tap water samples affect concrete strength.
