Major cement supply changes / certification
• Major players are currently ramping up imported products• parity matching rather than ATIC ‘unproven’ clinker imports
• ATIC reg. currently relies on second-party monitoring (RMS Lab)• Third-party certification system in development, due 2015/6
(following other similar industry schemes)
• Until then …

New 3211 Clause for Source Changes
6.5.4 Clinker Source Changes
When a source of clinker, or raw feed for clinker production, is relocated outside of an existing production facility, whether situated within or outside Australia, of less than five square kilometres in area contiguously, the ATIC pre-registration of the cement affected will be considered void.
At any time where this occurs:
(a) collect new samples and re-test in accordance with Annexure 3211/L; and
(b) carry out new trial mixes to the relevant specifications using the modified cement.
Submit the test results from the above to either the Principal or RMS Materials Register (as appropriate) for approval at least 14 days prior to the commencement of production of concrete using the modified cement.

Reducing cement - impact on carbonation
![Page 20: RMS Specification 3211 – Cement Specification changes Moss... · RMS Specification 3211 – Cement Specification changes ... New cement sources - changes to RMS 3211 2. Minimum](https://reader034.vdocument.in/reader034/viewer/2022050814/5b1eedd47f8b9af1328c177c/html5/thumbnails/20.jpg)
Open question
• Should the lower limit on cement content limit be reduced? (AKA: is carbonation really that much of a risk?)
• Why?
