Conclusion:
ASTM C150/C150M-22 is the verified, current gold standard for portland cement in North America and many other regions. If you are writing a concrete specification, QC plan, or material purchase order, use the verified PDF from ASTM directly – not a free third-party copy. The -22 revision offers only minor clarifications, so if you already have -21, an upgrade is not urgent. However, if you hold C150-19 or older, update now to avoid referencing obsolete limits (especially MgO and air content).

C150/C150M Standard Specification for Portland Cement - ASTM
ASTM C150/C150M-22 standard is the international specification for Portland cement
, providing the benchmark for its chemical and physical requirements. This 2022 edition was a key update before being superseded by the 2024 version. Key Cement Types
The specification categorizes Portland cement into ten distinct types based on their intended application: 分析测试百科网 For general use when no special properties are required.
For general use, specifically when moderate sulfate resistance is needed. Type II(MH):
Designed for moderate sulfate resistance and moderate heat of hydration. Used when high early strength is required. Specifically for low heat of hydration. For use where high sulfate resistance is essential. "A" Designations (IA, IIA, etc.): These indicate air-entraining versions of the above types. 分析测试百科网 Essential Requirements
The standard outlines strict criteria for the composition and testing of these cements: Ingredients:
Primarily Portland cement clinker, water, and calcium sulfate. It permits up to 5.0% limestone Chemical Properties:
Sets limits on aluminum oxide, ferric oxide, magnesium oxide, and sulfur trioxide. Physical Properties:
Defines standards for compressive strength, fineness (air permeability), heat of hydration, and setting time (Vicat or Gillmore needles). Provides values in both (metric) and inch-pound units
; these systems must be used independently to ensure compliance. iTeh Standards C150 Standard Specification for Portland Cement - ASTM

ASTM C150/C150M-22 is the standard specification for Portland cement, providing the benchmark for manufacturing, testing, and quality control in the construction industry. This 2022 edition was published in July 2022 and supersedes the previous 2021 version. 1. Core Scope and Cement Types
The standard identifies ten specific types of Portland cement, categorized by their performance characteristics and intended environment:
Type I: General-purpose cement used when special properties are not required.
Type II: Provides moderate sulfate resistance and moderate heat of hydration.
Type II (MH): Specifically for general use requiring moderate heat of hydration and moderate sulfate resistance.
Type III: Formulated for high early strength, typically used when forms need to be removed quickly.
Type IV: Low heat of hydration, used in massive structures like dams to prevent thermal cracking.
Type V: High sulfate resistance for use in soils or water with severe sulfate exposure.
Air-Entraining Variants (Types IA, IIA, IIIA, II(MH)A): Contain additions that create microscopic air bubbles to improve freeze-thaw durability. 2. Material Composition
