When a draft ACI Standard is processed through ACI's ANSI-approved standardization procedures, it is made available to public review for a 45-day discussion period. If there are any draft ACI Standards available for public discussion, links to those drafts are provided below.

You are invited to read these draft ACI Standards and provide comment. Please note that these drafts are not yet official ACI Standards.

Comments should be e-mailed to discussion@concrete.org or mailed to Jessie L. Bournay, Manager, Technical Documents, American Concrete Institute, 38800 Country Club Drive, Farmington Hills, MI 48331. Comments must be received by the end of the public discussion period.

All comments will be responded to by the originating committee. After the committee response is approved, comments and responses will be posted on this web page for 90 days.
