Low heat cement is the correct answer.

I also agree low heat cement should be the answer.

Lower Heat of Hydration.

Option D is correct.

Where the minimum dimension of the concrete to be placed at a single time is greater than 500 mm and especially where the cement content is 400 kg/m3 or more, measures to reduce the temperature such as using a material with a slower release of heat hydration should be considered. Cement generates a large amount of heat during the hydration process. Slag hydration is an exothermic reaction but it does not react as quickly as OPC and thus generates heat more slowly. Peak concrete temperatures are reduced. This is an advantage when thermal cracking would be a problem.

Low heat cement.

@All.

In question, avoided word is used. So the given option is correct.

It should be Low heat cement.

How heat cement is correct answer (blast furnace slag cement is use in sea water)?

@Sudip,

You mean the correct answer is blast furnace slag cement?

No guys, low heat cement is only used for thick RCC structures like dams, retaining walls, bridge abutments, etc. So that's not the correct answer.

Agree @Jayasrisiva.

The low heat cement should be the answer here!
