White cement is a specialized type of cement commonly used in the construction industry for decorative purposes such as flooring or tiles, precast concrete works, and in the production of architectural concrete. It is named so because it is characterized by its white color, which is obtained by using high-purity limestone and other additives that give it its distinctive color.
One of the primary reasons why white cement is more expensive is due to the high cost of its raw materials. As mentioned earlier, the high-purity limestone used to produce white cement is far more expensive than the ordinary limestone used in the production of regular cement. Additionally, the other additives used in the production of white cement, such as white silica sand, whiting, alumina, and iron oxide, are also more expensive.
Another reason for the higher cost of white cement is that it requires more energy during the manufacturing process. During the production of white cement, a higher temperature is required as compared to regular cement, making it more energy-intensive. This increased energy consumption leads to a higher cost of production, which is reflected in the final price of the product.
White cement is also a specialty product that requires specific handling, packaging, and storage. As compared to regular cement, white cement requires more high-end packaging and storage systems to protect its color from UV rays and other environmental factors that could affect its purity. Therefore, higher storage and handling costs lead to a higher price for the consumer.
White cement is more expensive due to the high cost of its raw materials, the increased energy consumption during manufacturing, and the specialized handling, packaging, and storage requirements. Despite its higher cost, white cement is preferred by builders, architects, and designers for its purity and versatility in decorative projects.

It is important to note that the strength of cement alone does not determine the overall strength of a concrete structure, as it also depends on the quality and proportions of other materials used, such as aggregates, water, and admixtures. The design, construction, and maintenance of the structure also play a crucial role in ensuring its strength and durability.
What is the strongest type of cement?
The strongest type of cement is generally considered to be Portland cement. This type of cement was first produced in the early 19th century and has since become one of the most commonly used cement types in the world. Portland cement is made up of several components including limestone, shale, clay, and iron ore.
The production process of Portland cement involves crushing and grinding these raw materials before heating them in a kiln at high temperatures. The resulting material, called clinker, is then ground into a fine powder and mixed with a small amount of gypsum to create the final product.
The strength of Portland cement comes from its ability to chemically react with water, a process known as hydration. When Portland cement and water are mixed together, the resulting reaction produces a strong, durable material that is resistant to many types of damage, including weathering, erosion, and chemical attacks.
Because of its strength and durability, Portland cement is used in a wide range of applications, from constructing buildings and roads to making concrete blocks, pipes, and other precast concrete products. It is widely available and relatively inexpensive, making it a practical choice for many construction projects.

For example, there are high-strength cements that are designed to withstand extreme conditions, such as those found in oil-well drilling operations or in high-traffic areas of highways and bridges.
There are also specialty cements, such as refractory cement, that are used in high-heat applications like furnaces and kilns.
The choice of cement depends on the specific needs and requirements of each project. However, when it comes to general strength and durability, Portland cement is widely regarded as the strongest type of cement available.
Why is some concrete white and some grey?
Concrete is a mixture made of a combination of cement, water, aggregates like sand, gravel or crushed stone, and sometimes added chemical admixtures. The color of concrete can vary greatly depending on the type and amount of materials used in the mixture, as well as the environmental conditions it is exposed to during the curing process.
Typically, there are two types of colors for concrete, white and grey. Grey concrete is the most commonly used type, and it is made by using Portland cement as the binding agent, sand and gravel or crushed stone as the aggregates, and water. Portland cement contains iron, which gives the concrete its grey color.
On the other hand, white concrete is produced using white Portland cement, which has a lower iron content than grey cement. The white color is more appealing aesthetically and makes it more suitable to be used in architectural and decorative applications such as flooring or walls.
Moreover, the color of concrete can be influenced by the type and color of the aggregates used. For example, a higher proportion of dark-colored aggregates like black basalt or granite will give the concrete a darker grey appearance.
Other factors may also affect the color of concrete, such as the amount of water used to mix the concrete, the curing conditions, and the exposure to the elements over time. Water or moisture can cause discoloration in concrete over time, turning it from grey to a greenish hue due to algae growth, or reddish-brown because of rust produced by steel reinforcement.
To conclude, concrete color is affected by the type and color of the materials used in the mixture, as well as the environmental factors that influence the curing process. Understanding these factors is critical for creating aesthetically pleasing, long-lasting, and durable concrete structures.

Does white cement waterproof?
White cement is a type of cement that is essentially the same as ordinary Portland cement but with the addition of certain compounds that make it white. It is commonly used in construction projects that require a smooth and even finish such as walls, floors, and decorative cement structures. However, when it comes to waterproofing, white cement does not make the cut.
While white cement is known for its strong adhesive properties, it is unfortunately not waterproof. The water-resistant qualities of cement are determined by its ability to prevent water from seeping through or penetrating its surface. While the materials used to make Portland cement provide a certain level of water resistance, this is not enough to make it waterproof.
To make cement waterproof, one must use additives or admixtures that have hydrophobic properties. These additives repel water and make the cement impervious to water penetration. These hydrophobic substances can be added in the form of liquid, powder or resin and can be mixed with the cement mix to improve its water resistance.
One common example of a hydrophobic additive used in cement is acrylic. Acrylic resins are added to cement mixtures to improve water resistance and give it a glossy finish. These additives are commonly used in the manufacture of waterproofing membranes and coatings for roofs, basements, and swimming pools.
White cement is a versatile building material that is commonly used in construction projects, but it does not have waterproofing capabilities. When it comes to waterproofing, it is essential to use additives or admixtures that have hydrophobic properties to ensure that the cement remains impervious to water penetration.
Does white concrete fade?
Yes, white concrete can fade over time due to various external factors. White concrete contains white Portland cement, which is prone to discoloration when exposed to ultraviolet (UV) rays from sunlight or other sources. The exposure to sunlight can cause the concrete to yellow or develop a grayish hue, detracting from its original pristine white appearance.
Additionally, exposure to airborne pollutants can also cause white concrete to lose its color. Pollutants from industrial factories or vehicles can settle on the surface and react with the concrete’s pigments, causing it to discolor.
