TYPE | Typical Use |
| I - General Purpose | Commenly used for general structural work where special properties are not required |
| II - Modified | Used for a moderate exposure to sulfite attack or a moderate heat of hydration is required. Type II cement gains
strength somewhat slower than Type I |
| Type III - High Early Strength | As it's name indicates, Type III is used when early strength is required. It's strength will typically develop
in 3 days compared to the 28 day strength of a Type I or II. Type III has a high heat of hydration and should not be used in mass concrete placements. |
| Type IV - Low Heat | Typically used for mass concrete placement. Type IV will gain it's strength relatively slowly. |
| Type V - Sulfite Resistance | Used where the exposure to sulfites is high such as structures exposed to seawater. |
