Low-heat cement is used in dam construction for several reasons:

Reduced Thermal Cracks: Low-heat cement helps minimize the likelihood of thermal cracks in thick concrete sections, which is crucial for the structural integrity of dams.

Balancing Temperature Rise: In mass concreting projects like dam construction, where large volumes of concrete are used, low-heat cement is preferred to balance the temperature rise during the hydration process. This helps prevent excessive heat generation that could lead to thermal issues.

Improved Durability: The use of low-heat cement contributes to improved durability performance of the dam structure, ensuring its long-term stability.

For the construction of Hydraulic structures like Dams, weirs etc, Normally Pozzolana Cement is used.

Low heat cement for mass constructions lika dams.

Blast furnace slag used only M 20 grade.

For dam m30 grade used so used low heat cement.

The quick setting is cement generally used in under running water and for construction of massive dams, we will use generally low heat Portland cement.

Blast furnace slag cement should be used for bridge.
