Keywords

None Provided

Rationale

Many new supplementary cementing materials are emerging and this revision will require the new SCMs to be evaluated through the concrete prism test first followed by the quicker mortar bar test in the future if it passes the concrete prism test. In addition SCMs with high alkali contents are now mentioned by name in Note 11.
