In the construction industry, cement is a binding substance that sets and hardens to bond to building components like stones, bricks, and tiles. Limestone (calcium), sand or clay (silicon), bauxite (aluminium) and iron ore, as well as shells, chalk, marl and shale, clay, blast furnace slag and slate are often used ingredients in cement. This fine powder is made by grinding the basic materials in cement production plants and heating them to produce a rock-hard substance. A chemical reaction occurs when cement is combined with water, forming a paste that sets and hardens to join the various components of a building.
Different Types of Cement
Cement is divided into mainly two types based on its hardening and setting mechanisms. These are as follows:
Hydraulic cement is, as the name implies, a type of cement that hardens when exposed to water. Non-hydraulic cement is made from limestone, clay, and gypsum. Hydraulic Cement is made by burning this raw material at a very high temperature.
There is no need for water to harden the non-hydraulic cement. As a result of CO2 from the atmosphere, it obtains. To harden, this sort of cement requires a dry environment. Raw materials for non-hydraulic cement include gypsum plasters, lime, and oxychloride. Non-hydraulic cements include slaked lime, for instance.
In addition to these primary categories, there are another types of cement is White Cement
With the exception of its colour, white cement is quite identical to ordinary Portland cement. Iron oxide and manganese oxide are present in only trace amounts in White Cement. It is more costly than OPC, making it uneconomical for routine work.
Color is quite essential from the standpoint of an architectural point of view when it comes to a construction. The use of white cement results in a concrete that is perfectly smooth and consistent in colour throughout. By incorporating pigments into white cement, it is possible to get very light shades of pastels and other colours that are not feasible with the more often used grey Portland Cement. In addition, there are several applications for White Portland Cement.
Forecast for the White Cement Market
There was $7,966.5 million worth of white cement market in 2017 and it is expected to reach $10,904.1 million by 2025, with a CAGR of 4.0 percent between 2018 and 2025. In 2017, the worldwide end-use market was split about 46.9 percent between the residential and commercial segments.
It’s becoming increasingly popular to use aesthetically pleasing building materials like white cement boards, panels and other materials in decorative applications. Asian and Middle Eastern & African areas have seen significant expansion in the building industry. White cement’s outstanding properties, such as its moisture and heat resistance, will fuel industrial expansion. Individual housing complexes will be in high demand due to the burgeoning population in cities around the world. Infrastructure projects including rail, motorways, and airport expansions are projected to stimulate market growth in the future.
The worldwide white cement market is segmented into three categories: type, end use, and geography.
- According to its type, it is divided into three categories: white Portland cement, white masonry cement, and other varieties.
- Residential, commercial, and industrial are the three types of end use that are classified.
- It is divided into five regions: North America, Europe, Asia-Pacific, Latin America, and the Middle East and Africa.
The following are the primary characteristics of White Portland Cement:
- In the case of white cement, the colour of the cement is a very essential consideration. As a result, the most important considerations are uniformity in brightness and tone.
- The colour of white cement is affected by the quality of the raw materials used as well as the manufacturing method.
- This cement is created from raw materials that contain extremely little Iron Oxide and Manganese Oxide, making it environmentally friendly. The brightness and undertone of white Portland cement are influenced by these oxides.
- China clay is commonly used in white cement, along with other materials such as chalk or limestone.
- Because of the presence of coal ash in white cement, oil is used as fuel for the kiln in order to prevent contamination.
- Special care should be taken during the white cement production process to ensure that it is as safe as possible.
- The chemical composition and physical qualities of white cement are in accordance with the standards for Type I Portland cement.
