Portland cement
The type of cement used as binder for the preparation of concrete or portland cement concrete. When portland cement is mixed with water, yields a product with features plastic adherent properties which solidifies and hardens in a few hours over a period of several weeks to acquire their resistance characteristic. With the addition of particular materials for cement (limestone or lime) is obtained plastic cement, which passes more quickly and more easily workable. This material is used in particular for the external cladding of buildings.
