Low heat of hydration cement is a type of hydraulic cement that generates less heat during the setting and hardening process compared to ordinary Portland cement. This is achieved by modifying the composition of the clinker and using raw materials that produce a slower reaction between the cement and water.
The reduced heat of hydration is important in large concrete structures, such as dams and high-rise buildings, where the buildup of heat can cause cracking and damage to the concrete. By reducing the heat of hydration, low heat of hydration cement helps to ensure the stability and durability of the structure over time.
In terms of properties, low heat of hydration cement has similar strength, durability, and resistance to chemical attacks as ordinary Portland cement. However, its slower setting time means it is not suitable for applications where a rapid setting time is required.
Low heat of hydration cement is typically more expensive than ordinary Portland cement due to its specialized production process and the need for higher quality raw materials.
Overall, low heat of hydration cement is a specialized type of hydraulic cement designed for large concrete structures where the buildup of heat can cause cracking and damage. Its reduced heat of hydration helps to ensure the stability and durability of the structure over time.

In terms of properties, low heat of hydration cement has similar strength, durability, and resistance to chemical attacks as ordinary Portland cement. However, its slower setting time means it is not suitable for applications where a rapid setting time is required. It is typically used in large concrete structures where the buildup of heat is a concern, such as in dams, high-rise buildings, and other infrastructure projects.
Low heat of hydration cement is typically more expensive than ordinary Portland cement due to its specialized production process and the need for higher quality raw materials. This can be offset by the reduced risk of cracking and damage to the concrete, which can result in long-term cost savings.
In conclusion, low heat of hydration cement is a specialized type of hydraulic cement designed for use in large concrete structures where the buildup of heat can cause cracking and damage. Its reduced heat of hydration helps to ensure the stability and durability of the structure over time, although its slower setting time and higher cost must be considered when making a decision to use this type of cement.
