Its most important property is low total heat of hydration. It is, therefore, very suitable for the construction of dams and mass concrete work. Concrete made from super sulphated cement may expand if cured in water and may shrink if the concrete is cured in air. In contrast, a significant advantage of Super sulphated Cement is that it has comparatively high resistance to chemical attack.

Pick the correct statement with regard to super sulphated Cement:a)It...
Super sulphated cement is a type of cement that is formed by grinding a mixture of granulated blast furnace slag (80-85%), calcium sulfate (10-15%), and Portland cement clinker (5-10%). It is commonly used in construction due to its unique properties. Among the given options, option C - "It has comparatively high resistance to chemical attack" is the correct statement. Let's discuss why.
High Resistance to Chemical Attack:
Super sulphated cement has a high resistance to chemical attack compared to other types of cement. This is primarily due to the presence of blast furnace slag, which contains reactive compounds such as calcium aluminate and calcium silicate hydrates. These compounds provide a protective layer on the surface of the concrete, making it less susceptible to deterioration caused by chemical reactions with aggressive substances such as sulfates and acids. This property makes super sulphated cement suitable for use in environments where chemical exposure is a concern, such as wastewater treatment plants and industrial facilities.
Other Properties of Super Sulphated Cement:
Although options A and B are incorrect, it is worth mentioning some other important properties of super sulphated cement for a comprehensive understanding:
- Total Heat of Hydration: Super sulphated cement does not have a high total heat of hydration. In fact, it has a lower heat of hydration compared to Portland cement, which makes it advantageous in situations where excessive heat generation during the curing process needs to be controlled.
- Expansion and Shrinkage: Concrete made from super sulphated cement does not exhibit significant expansion or shrinkage when cured either in air or water. This is because the chemical reactions involved in the hydration process of super sulphated cement do not cause significant volume changes.
In conclusion, super sulphated cement is known for its high resistance to chemical attack, making it a suitable choice for environments where chemical exposure is a concern. While it does not have a high total heat of hydration and does not cause significant expansion or shrinkage, these properties are not its most important characteristics.
