Explain anyone, please.

Blast furnace slag is suitable to MARINE structures as it has less heat of hydration and suited to MASSIVE constrction.

Since we used granulated blast furnace slag (pozzolona material) it has the property of HYDRAULICITY.

Hence it doesnt the correct answer.

Correct option is LOW HEAT CEMENT.

It attains slow rate of strengthening hence it is mainly suited to the construction of MASSIVE STRUCTURES it is not preferred to thin concrete works.

Agree @Jayasrisiva.

The low heat cement should be the answer here!

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.

@Sudip,

You mean the correct answer is blast furnace slag cement?

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

It should be Low heat cement.

@All.

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

Low heat cement.

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.
