. The site was near the ocean, where sulfate resistance was non-negotiable. Elias pulled up the ASTM C150 Standard Specification ASTM International official site
Measured via autoclave expansion to ensure the hardened paste won’t expand distortively over time.
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).
Are you writing a that requires specific testing protocol summaries?
Many universities, corporate libraries, and engineering firms maintain active subscriptions to ASTM Compass, granting employees and students access to fully verified PDFs.
You are following the latest testing methods and chemical limit requirements
The standard is comprehensive, featuring both inch-pound (C150) and SI (C150M) units to meet both U.S. and international requirements. Key Types of Portland Cement Covered (ASTM C150-22)
: Used when moderate sulfate resistance is needed.
