规定了用于在环境温度下保持液体的钢筋混凝土结构的设计和安装要求。本标准仅限于28天时极限抗压强度在20 MPa至50 MPa范围内的混凝土。对于这些结构，本标准补充并优先于AS 3600《混凝土结构》的要求。

Specifies requirements for the design and installation of reinforced concrete structures used for retaining liquids at ambient temperatures. This Standard is limited to concrete with ultimate compressive strength in the range 20 MPa to 50 MPa at 28 days. For these structures, This Standard supplements and takes precedence over the requirements of AS 3600, Concrete structures.
