Updated March 6, 2024
Understanding White Cement: Uses and Benefits

White cement is a versatile building material known for its aesthetic appeal and strength. It become  popular in the UK for both residential and commercial projects. But what exactly is white cement, and why is it chosen over traditional grey cement?

What Makes White Cement Unique?

Composition

White cement is similar to ordinary, grey Portland cement in terms of composition but differs in the raw materials used. It is manufactured with raw materials low in iron oxide and manganese oxide, the compounds primarily responsible for the grey colour of traditional cement. Limestone and clay are the main components, with a higher purity level compared to those used in grey cement.

Characteristics

The defining characteristic of white cement is its colour. It provides a neutral background that allows for vibrant colours when pigments are added making it a favourite among architects and designers. Besides its colour, white cement shares many of the same properties as grey cement, including strength and durability.

Uses of White Cement

White cement is incredibly versatile, with applications ranging from architectural and decorative to structural.

  • Architectural and Decorative Uses: It is widely used for pre-cast curtain walls and facades, due to its ability to produce brightly coloured finishes.
  • Structural Applications: While often chosen for its aesthetic qualities, white cement also meets structural requirements.

Benefits of Using White Cement

  • Aesthetic Appeal: The most obvious benefit is its aesthetic versatility. White cement can be used as a base for a wide range of colours, offering designers and homeowners creative freedom.
  • Reflectivity: Buildings using white cement in their construction benefit from higher reflectivity. This can lead to reduced energy costs, as less artificial lighting and cooling is required.
  • Durability: Like grey cement, white cement provides high durability and strength, ensuring structures withstand the test of time.

Considerations When Using White Cement

  • Cost: White cement is generally more expensive than grey cement due to the purity of raw materials and the more rigorous manufacturing process.
  • Availability: While widely available in the UK, it's always best to check with local suppliers for specific types or brands that meet your project's requirements.
  • Application Technique: Special care should be taken during application to avoid contamination with other materials, as this can affect the final appearance.
