What is water cement?

• A. The total amount of water used in the concrete mix relative to the amount of cement
• B. The ratio of cement to aggregate
• C. The chemical compound formed during hydration
• D. The water used for curing only

Answer: (A)

Water-cement ratio is the amount of water in the concrete mix relative to the amount of cement, usually expressed by weight. This ratio determines how much cement paste forms and how porous the hardened concrete will be. A higher ratio leaves more voids, making the concrete weaker and more prone to durability problems; a lower ratio produces a denser, stronger concrete but can be harder to work with unless you use admixtures to keep it workable. It isn’t about cement to aggregate (that’s a different mix proportion), nor about the chemical compound created during hydration, nor just the water used for curing after placement.
