AS 5146.2:2018

This Standard specifies requirements and sets out methods for the determination of the characteristic properties of Reinforced Autoclaved Aerated Concrete members (Reinforced AAC), with a thickness not less than 50 mm, for use in structures where the design and construction conform with AS 5146.1.
NOTES:
1 This Standard uses the term AAC (autoclaved aerated concrete material) and Reinforced AAC (wall, floor or roof panels or other members, consisting of AAC into which steel reinforcement has been cast).
2 Typical uses of Reinforced AAC include loadbearing and non-loadbearing wall panels for both internal and external use, fascias and cladding, roofs, floors, beams, lintels, piers, noise barriers and earth retaining structures.
3 This Standard does not cover the design or use of unreinforced AAC blocks.
4 This Standard does not cover the use of Reinforced AAC subject to dynamic loads, except loads due to earthquake.
5 This Standard does not cover finishes such as render, tiling, plasterboard and the like, fixings or supporting structures.
6 This Standard applies only to cases where—
(a) the design has been performed by an experienced structural engineer and design actions, material properties, section properties, bending moments, shears and deflections have been determined in accordance with the provisions of this Standard; and
(b) the execution of such work is carried out under the direction of appropriately qualified persons who are experienced in Reinforced AAC construction and who understand the structural requirements specified herein.
7 This Standard should not be interpreted in a way that prevents design using alternative materials or methods not specifically referred to herein. However, the design of such members is outside the scope of this Standard.
Means for demonstrating conformance with this Standard are given in Appendix AA.
