BS PAS 8820:2016 specifies the performance requirements for alkali-activated cementitiousmaterial comprising aluminosilicate main constituents and an alkali activator. AnAACM (including the activator) may contain Portland cement only at a content ofless than 5% mass of binder solids, and may contain subsidiary constituents notexceeding 25% of the mass of the cementitious material. It also specifies a meansof assessing concrete obtained through the use of such cementitious materialfor performance and durability, and sets requirements for the alkali-activatingcomponent and the aluminosilicate powder component of these concretes.

NOTE 1 The term “geopolymer” is not used in this PAS, but this does not exclude itsuse for descriptive purposes in conjunction with alkali-activated cementitious materials.

This PAS does not:

  • set detailed requirements for the composition of the alkali-activatedcementitious material;
  • specifically address applications for such materials as renders, screeds, mortarsor repair materials, although it does not exclude the possibility that suchmaterials could be used for such purposes; or
  • cover the use of any material classified as hazardous waste.

NOTE 2 Hazardous waste is defined in the Technical Guidance of the UK EnvironmentAgency and includesradioactive materials.

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

NOTE 3 Attention is drawn to The Personal Protective Equipment Regulations 2002and The Health and Safety at Work etc Act 1974.

All current amendments available at time of purchase are included with the purchase of this document.
