Advanced Cements and Concretes Consortium

Summary

The National Institute of Standards and Technology (NIST), an agency of the United States Department of Commerce, in support of efforts to develop measurements and standards for advanced construction materials, has established the Advanced Cements and Concretes Consortium.

consortium goals

The initial focus of this consortium is to evaluate, develop, and standardize methods to characterize and quantify the carbon and carbonates in new cements and concretes. Test methods to specifically measure carbon in these materials are being explored. A later focus of the consortium will be to evaluate the suitability of current measurement standards to measure the material, mechanical, structural, and durability properties and, where appropriate, develop new test methods needed to help enable acceptance of advanced cements and concretes in the marketplace. NIST and industrial partners will perform research together with the following four goals:

• Evaluate the suitability of current ASTM standards to measure carbon, including specifically measuring carbon in cements, concretes, and the associated starting materials such as aggregates.
• Accurately measure the amount of carbon uptake by a material during CO₂ -curing processes. Validate the robustness and repeatability of the measurement method.
• Use these measurements as a foundation to propose tests(s) that can be standardized through the ASTM consensus process.
• Evaluate the applicability of current material, mechanical, structural, and durability tests used for cements and concretes to new low carbon cements and concretes. If needed, develop new tests or point out why old tests are not needed to help enable acceptance of these new materials in the marketplace.

No proprietary information will be shared as part of the Consortium. Participants will not be required to contribute any funds or pay any fee. Contributions of sample low carbon cements, concretes, and associated aggregates are highly encouraged.

CONSORTIUM MODEL

• Convenes industry, academia, and government to identify and address measurement and standards needs 
• Enables members to work with NIST to develop measurement solutions and standards
• Leverages NIST expertise in measurement science, standards development, reference materials, technology development, and basic research
• Collaborates with related programs at other federal agencies 

WHY NIST

• Cross-disciplinary expertise in engineering, and the physical, information, chemical, and biological sciences
• As a non-regulatory agency of the U.S. Department of Commerce, NIST does not impose standards; standards are accepted by consensus
• Neutral convener for industry consortia, standards development organizations, federal labs, universities, public workshops, and interlaboratory comparability testing
