To ensure the authenticity and accuracy of the ASTM C150/C150M-22 PDF, it is essential to verify it through official channels. Here are the steps to verify the document:
The most straightforward verification method is knowing where the PDF came from. Legitimate ASTM standards can only be obtained through:
Air-entrained version of Type II(MH).
Air-entrained version of Type III.
ASTM actively pursues copyright infringement cases. The organization has brought legal actions alleging copyright infringement, contributory copyright infringement, trademark infringement, unfair competition, and false designation.

The direct publisher of the standard.
For use when high early strength is required (e.g., fast-track construction or cold-weather concreting). Type IIIA: Air-entraining cement corresponding to Type III.
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
The designation provides distinct protocols for both standard inch-pound measurements and metric (SI) equivalent units. The standard explicitly notes that each measurement framework must be evaluated independently to maintain structural math integrity; combining values from the two frameworks violates compliance mandates. To ensure the authenticity and accuracy of the
): Limits to prevent premature stiffening or long-term sulfate expansion.
Determined via air-permeability tests (Blaine fineness). Finer cement (like Type III) hydrates faster, accelerating strength gain.
Any deviation—such as “ATSM” instead of “ASTM,” missing hyphens, or incorrect dates—indicates a potentially counterfeit document.
| 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 | Air-entrained version of Type III
To stay informed about updates to ASTM C150/C150M:
In civil engineering and commercial construction, using an unverified, outdated, or bootleg copy of an ASTM standard introduces severe compliance and liability risks. Looking for a ensures: Legal and Contractual Compliance
The 2022 version explicitly details the following categories: : General use when no special properties are required. : For general use, specifically when moderate sulfate resistance is needed. Type II(MH)
The 2022 standard covers the following types, designed for specific construction environments:
Cement covered by this specification shall contain only the following ingredients: Portland cement clinker; water or calcium sulfate (or both); limestone; processing additions; and air-entraining addition for air-entraining Portland cement.
