AASHTO M 85-17 Standard Specification for Portland Cement (ASTM Designation: C150/C150M-17)
: Brown Technical Book Store
This specification covers ten types of portland cement as follows: Type I-For use when the special properties specified for any other type are not required. Type IA-Air-entraining cement for the same uses as Type I, where air-entrainment is desired. Type II-For general use, more especially when moderate sulfate resistance or moderate heat of hydration is desired. Type IIA-Air-entraining cement for the same uses as Type II, where air-entrainment is desired. Type III-For use when high early strength is desired. Type IIIA-Air-entraining cement for the same use as Type III, where air-entrainment is desired. Type IV-For use when low heat of hydration is desired. Type V-For use when high sulfate resistance is desired. Note--Some cements are designated with a combined type classification, such as Type I/II, indicating that the cement meets the requirements of the indicated types and is being offered as suitable for use when either type is desired.
