Standard Specification for Portland Cement
Also Known As:
The AASHTO M 85-20 standard provides guidelines for ten different types of portland cement. Each type is designed for specific purposes and possesses different properties.
Type I is recommended for general use when the special properties of other types are not required. Type IA is an air-entraining cement used for the same applications as Type I, with the added benefit of air entrainment.
Type II is suitable for general use, particularly when moderate sulfate resistance is needed. Type IIA is an air-entraining cement that serves the same purposes as Type II but with air entrainment properties.
Type II(MH) is used when moderate heat of hydration and moderate sulfate resistance are desired. Type II(MH)A is an air-entraining cement that has the same applications as Type II(MH), with the additional benefit of air entrainment.
Type III is recommended when high early strength is required. Type IIIA is an air-entraining cement used in the same situations as Type III but with air entrainment properties.
Type IV is utilized when low heat of hydration is desired. Lastly, Type V is recommended for use when high sulfate resistance is needed.
