Cement render or cement plaster is the application of a mortar mix of sand and cement, (optionally lime) and water to brick, concrete, stone, or mud brick. It is often textured, colored, or painted after application. It is generally used on exterior walls but can be used to feature an interior wall. [1]
It requires a much lower content in colored impurities in the raw materials (essentially limestone and clay) used to produce clinker: low levels of Cr 2 O 3, Mn 2 O 3, and Fe 2 O 3), but above all, a higher temperature is needed for the final sintering step in the cement kiln (1600 to 1700 °C in place of 1450 °C for ordinary Portland cement ...
