A long-standing primary distributor for technical standards with direct access to ASTM's historical catalog.

ASTM C150/C150M-22 is the 2022 edition of the ASTM standard that specifies the chemical and physical requirements for Portland cement — the most widely used cement type in concrete and mortar worldwide. For engineers, contractors, specifiers, and concrete producers, this standard is a cornerstone: it defines cement types, performance limits, testing methods, and labeling requirements that ensure consistency, safety, and predictability in construction.

| 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 c150m22 pdf verified

Tested using mortar cubes at specific intervals (e.g., 3 days, 7 days, 28 days). Setting Time: Determined using the Vicat needle test. Why a "Verified PDF" Matters

For use when high early strength is required (e.g., fast-track construction). Type IIIA: Air-entraining high early strength cement. | Type | Designation | Primary Application |

Authentic ASTM PDF standards are protected by . The DRM system, typically implemented through FileOpen software, provides multiple layers of protection:

Air-entrained version of Type II.

: Manufactured to develop rapid compressive strength within the first few days of hydration. It enables early structural load-bearing and rapid formwork removal. Type IIIA : Air-entraining version of Type III. Type IV (Low Heat of Hydration)

✅ The 2022 edition still uses Bogue equations (Section X2) for compound composition, but includes a note that direct X-ray diffraction may be used as an alternative when agreed upon. Type IIIA: Air-entraining high early strength cement

ASTM C150/C150M-22 is a standard that outlines the requirements for eight types of Portland cement, which are commonly used in construction. These types include:

One of the most frequent points of confusion is the number of cement types covered. This depends on whether we are listing the eight core types or the ten outlined including air-entraining variations. According to the full text of the standard, :
