Codes of Best Practice are ‘how-to’ documents which give information, advice and techniques to improve the construction process. Their role is to improve the benefits for all participants and produce better buildings. Codes of Best Practice apply to everyone involved in a project to bring about a more inclusive culture and reduce barriers to improved performance. A Code of Best Practice for the Use of Aircrete Blockwork [1] has been prepared for use in the UK and will be published in 2002. Aircrete is also known as Autoclaved Aerated Concrete (AAC). The Code of Best Practice brings all of the appropriate information, advice and techniques for design, specification and construction of Aircrete blockwork into a single source. The guidance for design includes advice on a range of practical technique such as suitable jointing mortars, finishes, fixings, movement joints and recommended site practices. The advice in this simple-to-use code should enable the creation of best value, more efficiently constructed Aircrete blockwork within the context of UK masonry construction. The Aircrete producers intend to make the publication available in easy-to-access hard copy and electronic forms through the Autoclaved Aerated Concrete Products Association (AACPA).
