This standard serves as a voluntary consensus guideline to establish quality control in the manufacture and application of Portland cement. It defines the allowable ingredients, including Portland cement clinker, calcium sulfate, water, limestone, and processing additions. The specification is issued under a "dual designation," meaning it provides requirements in both and inch-pound (imperial) units, which must be used independently to avoid non-conformance. Classification: The Ten Types of Portland Cement
: Air-entraining variant of the Type II(MH) classification.
Despite the release of newer specifications like ASTM C1157 (performance-based cement specification), ASTM C150/C150M remains the dominant standard for Portland cement in North America and many international markets. ASTM C150/C150M continues to be referenced in countless project specifications, building codes, and regulatory frameworks.
For users requiring the specific differences between the 2021 and 2022 editions, ASTM offers —documents that visually highlight every change made from the previous edition. A redline PDF shows additions, deletions, and modifications, allowing engineers to quickly assess the impact of the revision on their work.
| Type | Designation | Primary Application | |------|-------------|---------------------| | Type I | General Purpose | When no special properties are required | | Type IA | Air-Entraining Type I | Same as Type I, with air-entrainment | | Type II | Moderate Sulfate Resistant | For general use where moderate sulfate resistance is desired | | Type IIA | Air-Entraining Type II | Same as Type II, with air-entrainment | | Type II(MH) | Moderate Heat + Moderate Sulfate | For general use where moderate heat of hydration and sulfate resistance are desired | | Type II(MH)A | Air-Entraining Type II(MH) | Same as Type II(MH), with air-entrainment | | Type III | High Early Strength | When rapid strength gain is needed | | Type IIIA | Air-Entraining Type III | Same as Type III, with air-entrainment | | Type IV | Low Heat of Hydration | For massive concrete structures | | Type V | High Sulfate Resistance | For exposure to severe sulfate conditions |

ASTM C150/C150M-22 is titled "Standard Specification for Portland Cement." This standard outlines the requirements for six types of Portland cement, which are used in construction. These types include:
– same chemical limits plus air content of 12–18% for mortar (ASTM C185).
The official 2022 edition—developed under the jurisdiction of —bridges international sourcing requirements by providing dual values in both SI and inch-pound units, which must be maintained independently to avoid non-conformance. Classification of the 10 Portland Cement Types
: Engineered for general concrete work exposed to moderate sulfate levels in water or soil. Type IIA : Air-entraining version of Type II.
Do you need guidance on how (blended cements)?
Resistant to moderate sulfate action; ideal for structures in contact with soil or groundwater.
ASTM C150/C150M is a standard specification issued by ASTM International. It covers eight distinct types of portland cement. The designation "C150" represents the standard number, while "C150M" indicates that the document includes both metric and inch-pound units.
