Polymer cements are materials made by replacing the cement at least partly with polymers. Cements can be modified by latex, dispersions, polymer powders, water-soluble polymers, liquid resins, and monomers.
When the polymer is used in small amounts, it modifies only the pore structure and dose not behave like a binder.
The addition of polymer changes the properties of the set cement. The water to cement ratio is reduced with the increase of the polymer-to-cement ratio. This influences the mechanical properties. The polymer content results in the change of the properties.
