62  Definitions
 (1) In this Part:
cement means any hydraulic cement, including general purpose and blended cements, meeting the minimum requirements for such cements set out in AS 3972—2010 or any other specific contract and export specifications.
 Note: In 2020, AS 3972—2010 was available from http://www.standards.org.au.
Portland cement clinker means the Portland cement clinker resulting from clinker production which:
 (a) has a concentration of calcium silicates equal to or greater than 60% by mass; and
 (b) has a concentration of magnesium oxide (MgO) equal to or less than 4.5% by mass; and
 (c) is useable in the making of Portland cement.
supplementary cementitious material means any mineral additive to cement which meets the minimum requirements for such additives set out in any of Australian Standards AS 3582.1:2016, AS 3582.2:2016, AS 3582.3:2016 or AS 3582.4:2022, or any other specific contract and export specifications.
 Note: In 2023, each of the Australian Standards was available from http://www.standards.org.au.
 (2) In this Part the activity of clinker production is the physical and chemical transformation of:
 (a) either or both of calcium carbonate compounds (limestone (CaCO3)) and other calcium carbonate (CaCO3) feedstocks; and
 (b) any of the following:
 (i) clay;
 (ii) clay mixed with 1 or more feedstocks that contain 1 or more of the following:
 (A) silicon dioxide (SiO2);
 (B) iron (Fe);
 (C) aluminium oxide (alumina (Al2O3));
 (iii) 1 or more feedstocks that, when combined, contain all of the following:
 (A) silicon dioxide (SiO2);
 (B) iron (Fe);
 (C) aluminium oxide (alumina (Al2O3));
that are fused together at a temperature above 1000 °C into Portland cement clinker.
