The revision is exploring the potential of increasing the approved mineral additions in general purpose cement up to 10% (presently at 5%). The drive behind this is to align New Zealand cement production with trends in world production with the aim of reducing green house gases from cement manufacture. The revised standard could see the percentage of mineral additions in cement increase by 5%. Dene Cook, Technical Manager, Firth, is the IPENZ representative on the Standards Committee and will keep us updated on the potential changes to the cement Standard in the next issue of ELEMENT.
