Answer: D. Blast furnace slag cement

Blast furnace slag cement is suitable for marine work.


Low heat portland cement

  • It contains high percentage of C2S and a low percentage of C3S and C3A.
  • Rate of development of strength is low.
  • Initial setting time should not be more than 60 minutes.
  • It is generally used in mass concrete work like dams, retaining walls, bridges etc.

Rapid hardening cement

  • It contains more C3S and less C2S as compared to Ordinary portland cement
  • Initial setting time should not be less than 30%
  • Ultimate strength of rapid hardening cement is equal to Ordinary portland cement.
  • It is used in road repair work,prestress concrete work etc.

Ordinary portland cement

  • Obtained by pulverizing argillaceous and calcareous material in proper proportion
  • Higher compressive strength at early stage
  • It is classified as 33 grade,43 grade,53 grade. The number 33,43 and 53 classified as 28 days characteristics compressive strength of cement
  • Commonly used in concrete construction work where there is no exposure to weather.

Blast furnace slag cement

  • It is obtained by mixing portland cement,granulated blast furnace slag and gypsum.
  • Low heat of hydration
  • High sulphate resistance capacity
  • Good resistance to marine effects.
  • Commonly used in marine work.
