Concrete is characterized by the type of mixture or cement employed, by the particular features it manifests, or via the solutions used to supply it. In standard structural concrete, the character with the concrete is largely based on a h2o-to-cement ratio. The lower the water content, all else staying equal, the more robust the concrete. The combination needs to have just enough water making sure that Each and every aggregate particle is totally surrounded through the cement paste, the Areas between the aggregate are loaded, and that the concrete is liquid enough to become poured and distribute effectively.
