Concrete is characterised by the sort of aggregate or cement employed, by the particular traits it manifests, or via the methods employed to make it. In everyday structural concrete, the character of the concrete is essentially based on a h2o-to-cement ratio. The lessen the h2o written content, all else being equivalent, the much better the concrete. The combination needs to have simply enough h2o to ensure that Every aggregate particle is totally surrounded via the cement paste, which the spaces among the aggregate are filled, and that the concrete is liquid enough to become poured and distribute correctly.
