Though all Portland cement is basically the same, eight types of cement are manufactured to meet different physical and chemical requirements for specific applications:

  • Type I is a general purpose Portland cement suitable for most uses.
  • Type II is used for structures in water or soil containing moderate amounts of sulfate, or when heat build-up is a concern.
  • Type III cement provides high strength at an early state, usually in a week or less.
  • Type IV moderates heat generated by hydration that is used for massive concrete structures such as dams.
  • Type V cement resists chemical attack by soil and water high in sulfates.
  • Types IA, IIA and IIIA are cements used to make air-entrained concrete. They have the same properties as types I, II, and III, except that they have small quantities of air-entrained materials combined with them.
