    Abstract - (Show below) - (Hide below)

    Sets out the requirements for chemical admixtures to be added to concrete mixes incorporating portland and blended cements.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for chemical admixtures to be added to concrete mixes incorporating portland and blended cements.NOTES: 1 Sampling procedures are given in Appendix A.2 Information on admixtures for use in concrete is given in Appendix B.3 Guide to determine the chloride ion content in admixtures is given in Appendix C.4 Information on thickening admixtures is given in Appendix D.5 Information on shrinkage-reducing and shrinkage-compensating admixtures is given in Appendix E.6 Information on permeability-reducing admixtures is given in Appendix F.7 Admixtures that have been acceptance tested and approved to AS 14781992 and that meet the requirements of this Standard do not require re-assessment.
