Using unverified, pirated, or outdated drafts of ASTM standards introduces massive legal and structural risks to a project.

Cement must meet limitations on specific chemical compounds, including: Aluminum Oxide (Al₂O₃) Ferric Oxide (Fe₂O₃) Calcium Oxide (CaO) Magnesium Oxide (MgO) (Limiting to reduce expansion) Sulfur Trioxide (SO₃) (Controlled for soundness)

Determined by air permeability tests (Blaine fineness). Fine particles hydrate faster.

): Regulated to prevent expansion and unsoundness over time.
