How does low heat cement has less compressive strength?

Srinivas said: (Oct 13, 2015)  
For low heat cement heat of hydration is very low compare to other cement I think.

Anup Bhagat said: (Jul 1, 2016)  
I think low heat cement have high compressive strength.

Mahendra Shukla said: (Dec 10, 2016)  
Low heat cement have high Ultimate strength.

Ravindra Rathod said: (Mar 8, 2017)  
Low heat cement have less compressive because it shows high ultimate strength.

Gaurav said: (Nov 1, 2017)  
I think strength is not low.

Manirul said: (Feb 6, 2018)  
I think D is the correct answer.

Hitesh Nagar said: (Apr 19, 2018)  
Low heat cement has less early strength.

But ultimate strength is same as other cement. It is used for mass concrete work.

Ganesh said: (Jun 2, 2018)  
D answer is correct.

Low heat cement process high strength for example in dicalcium silicate it is low heat cement but process high strength so we use for Mass concrete works.

Anand Tiwari said: (Aug 18, 2018)  
Low heat cement generates low heat of hydration but the total heat generated is the same as the normal cement. We use low heat cement in mass concreting to avoid temperature stress in the internal zone and cracking. It does not affect the strength of concrete. Because strength depends on mix design we use and cement is one of the ingredients of concrete. Cement is not only the one who gives the strength in concrete. Initial and Final setting time is normal.

Hence D answer is correct.

Eliza Haque said: (Sep 18, 2018)  
Low heat setting time is 60 mins. Final setting time is 600 mins (IS:12600), used for mass concrete like dams. I have a doubt about its compressive strength.

Abdul Kalam said: (Oct 1, 2018)  
Low heat concrete is for use to dam construction purposes.

J J Radadiya said: (Mar 9, 2019)  
In Cement heat of hydration and early strength gaining properties due to C3A & C3S.

In law heat cement C3A & C3S content is less, thus heat of hydration is less . And low heat cement thus has less initial compressive strength compared to normal.

But, Ultimate strength of low heat cement is more than normal cement.

Devendar Uttarakhandi said: (Aug 14, 2019)  
In low heat cement c2s containt is high. It means least Heat of hydration and least rate of Hydration.
