Using white cement in prefabricated manufacturing provides early strength far greater than that possible with grey cements due to the superior strength characteristics of white cement. This is why it is preferred by pre-cast manufacturers. It is also the reason that white cement is preferred in historic structures, custom decorative applications, and cladding. The use of white cement in the production of color concrete and mortar with high gloss inorganic pigments provides the end user with excellent visual appearance in both indoor and outdoor applications. This article is a compilation of the benefits and technical advantages of using white cement in prefabricated manufacturing.

What is White Cement? Why is it Used?
What distinguishes white cement from grey Portland cements is the purity of the raw ingredients used to make it. White cement is preferred by pre-cast manufacturers to obtain a colorful, glossy and stable visual appearance, especially in products with a lighter hue. In addition to being used in structural and architectural concrete applications, it also makes it possible to manufacture products in a variety of colors including cladding, decorative plasters, and pool applications. There are other factors that influence the final color of pre-cast products.
- The whiteness of the cement
- The amount of pigment
- The color and cleanness of the aggregate
- The color of other additives
- The surface processing performed on the final product
- The amount of water
To minimize color changes in the production of pre-cast concrete, every component should be used from similar sources. Materials produced by the same manufacturer, such as cements, aggregates and additives, are very important in terms of color stability.
Technical Advantages of Using White Cement in Prefabricated Manufacturing
The technical advantages of using white cement in prefabricated manufacturing are listed below:
- Aesthetics
- High initial strength
- Low alkali content – resistance to alkali silica reaction
- Durability
- Increase in production speed and
- Quick removal from molds.
There are several technical and aesthetic advantages to using white cement in prefabricated manufacturing. Important technical advantages include high initial strength, resistance to alkali-silica reaction and quick removal from molds. White cement also provides an aesthetic appearance, so it is preferred in prefabricated manufacturing.
Why Should You Use White Cement in Pre-cast Manufacturing?
Concrete made from white cement is an essential part of many structures. White concrete is widely used in the construction sector, both in pre-cast applications and concrete poured on site. The use of white cement in these products provides users with not only decorative properties and durability, but the ability to create products with different colors as well. White cement is preferred for wall blocks, paving stones and other external cladding because it gives the final product the qualities of durability, strength and resistance to environmental factors.
