Concrete is characterised by the sort of combination or cement utilised, by the specific attributes it manifests, or because of the techniques utilised to make it. In ordinary structural concrete, the character in the concrete is basically determined by a water-to-cement ratio. The reduced the h2o content, all else being equal, the more powerful the concrete. The mixture will need to have just enough water to ensure that Each and every mixture particle is completely surrounded by the cement paste, which the spaces amongst the aggregate are filled, and which the concrete is liquid enough to become poured and distribute correctly.

A different innovation in masonry development is using prestressed concrete.
