What term is used to describe the ratio of water to cement in a mix?

The term used to describe the ratio of water to cement in a mix is indeed the water-cement ratio. This ratio is a crucial factor in determining the strength, workability, and durability of concrete. A higher water-cement ratio generally results in a weaker concrete mix, as excess water can lead to increased porosity and reduced mechanical strength after the cement hydrates. Conversely, a lower water-cement ratio can enhance strength and resistance to environmental factors, but it may make the mix less workable. Therefore, understanding and controlling the water-cement ratio is essential for achieving the desired performance characteristics of concrete in construction projects.
