Standards Organizations: Product specifications and test methods are typically developed by national standards development organizations, such as ASTM in the U.S. and CSA in Canada. Full consensus standards are developed with the participation of all parties who have a stake in the standards’ development and/or use. The table below lists the most relevant national and international standard organizations for the concrete industry. | U.S. and Canada | | ASTM | ASTM International. Has a history of more than 100 years of standards development activities, including the first national specifications for portland cement and other concrete materials. Uses a consensus-based standards development process. Committee C01 develops standards related to hydraulic cements and Committee C09 develops standards for concrete and other concrete materials. | | AASHTO | American Association of State Highway and Transportation Officials. Develops standards for many materials though participation of state departments of transportation staff. AASHTO’s Subcommittee on Materials develops concrete-related specifications, many of which are closely related to ASTM standards. | | CSA | Canadian Standards Association. Develops standards for use in Canada through a consensus process, including the CSA A3000 compendium on cementitious materials. | | International | | ISO | International Organization for Standardization. Cement-related standards are developed by TC (Technical Committee) 74 (Cement and Lime) and concrete-related standards by TC 71 (Concrete, reinforced concrete and pre-stressed concrete). | | CEN | European Committee for Standardization. EN 197 is the standard specification for cement in CEN member countries and EN 206 is the standard specification for concrete. | Product specifications and test methods are referenced in local and international building codes and specifications for ease of reference.

For concrete construction projects, other organizations, such as state DOTs or the FAA, also develop specifications that typically refer to ASTM or AASHTO specifications.
Cement Specifications
Different types of cement are manufactured to meet various physical and chemical requirements. There are currently three different common hydraulic cement standards for general concrete construction in use in the U.S.: - ASTM C150 (AASHTO M 85), Specification for Portland Cement
- ASTM C595 (AASHTO M 240), Specification for Blended Hydraulic Cements
- ASTM C1157, Performance Specification for Hydraulic Cements
Each of these three specifications provides for several different types of cement.
