This PAS specifies the performance requirements for alkali-activated cementitious material comprising aluminosilicate main constituents and an alkali activator. An AACM (including the activator) may contain Portland cement only at a content of less than 5% mass of binder solids, and may contain subsidiary constituents not exceeding 25% of the mass of the cementitious material. It also specifies a means of assessing concrete obtained through the use of such cementitious material for performance and durability, and sets requirements for the alkali-activating component and the aluminosilicate powder component of these concretes.<\/p>\n

\n
\n NOTE 1<\/i>\n <\/div>\n

The term\u201dgeopolymer\u201d is not used in this PAS, but this does not exclude its use for descriptive purposes in conjunction with alkali-activated cementitious materials.<\/i><\/p>\n<\/div>\n

This PAS does not:<\/p>\n

    \n
  • \n

    set detailed requirements for the composition of the alkali-activated cementitious material;<\/p>\n<\/li>\n

  • \n

    specifically address applications for such materials as renders, screeds, mortars or repair materials, although it does not exclude the possibility that such materials could be used for such purposes; or<\/p>\n<\/li>\n

  • \n

    cover the use of any material classified as hazardous waste.<\/p>\n<\/li>\n<\/ul>\n

    \n
    \n NOTE 2<\/i>\n <\/div>\n

    Hazardous waste is defined in the Technical Guidance of the UK Environment Agency () and includes radioactive materials [16]<\/span>.<\/i><\/p>\n<\/div>\n

    This PAS is for use by manufacturers of alkali-activated cementitious material, producers of prefabricated concrete elements containing alkali-activated cementitious material and producers of concrete containing alkali-activated cementitious material which is to be precast, delivered ready-mixed, or mixed in situ. It is also of interest to designers and specifiers as it provides a means of assessing the suitability of AACM concrete mixtures for typical construction uses.<\/p>\n
