This Standard sets out requirements for construction using Reinforced Autoclaved Aerated Concrete (Reinforced AAC) members conforming with AS 5146.1 and AS 5146.2, including associated fixings, flashings and control joints. This Standard does not cover the construction of structures consisting of unreinforced autoclaved aerated concrete blocks.
The systems described in Part 3 of this Standard nominate specific thicknesses of AAC panel. The Standard does not provide for the systems in Part 3 to be modified so as to include panel thicknesses other than those nominated.
NOTES:
1 The term ‘Reinforced AAC structures’ refers to buildings that incorporate ‘Reinforced AAC members’, such as walls, floors, roofs, beams and the like made of Reinforced AAC. In this Standard, the term ‘components’ refers to items made from other materials, such as bolts, fixings, flashings and the like.
2 The forms of construction and detailing prescribed in Sections 2 and 3, together with Sections 4, 5, 6, 7 or 8 for the applications described therein, satisfy the requirements of AS 5146.1. However, they are not the only forms of construction or details capable of doing so. Other construction and details may be assessed separately for conformance with AS 5146.1.
3 This Standard should not be interpreted in a way that prevents the design and construction of structures that use alternative materials or methods of design or construction not specifically referred to herein. However, the design and construction of such structures are outside the scope of this Standard.
4 This Standard is based on the assumption that the design information is conveyed to the builders via comprehensive documentation such as drawings, details and specifications.
