AS 3735-1991

Specifies requirements for the design and construction of concrete structures that contain reinforcing steel or tendons or both, used for retaining liquids at ambient temperatures. It is intended that the requirements of this Standard supplement and take precedence over the requirements of AS 3600.

This Standard specifies requirements that specifically relate to concrete structures and members, that contain reinforcing steel or tendons, or both, used for retaining liquids at ambient temperature.The Standard supplements and takes precedence over the requirements of AS 3600.The principles of concrete design and construction embodied in this Standard apply to structures and members made of concrete -(a) with a characteristic compressive strength at 28 days (f'c) in the range of 20 MPa to 50 MPa; and(b) of saturated, surface-dry density in the range of 1800 kg/m3to 2800 kg/m3. The Standard does not apply to the design of -(i) dams;(ii) aqueducts, hydraulic tunnels or similar structures;(iii) small septic tanks (see AS 1546);(iv) portable precast concrete water tanks of less than 25 000 L capacity;(v) fibre-impregnated concrete that does not comply with the design requirements and procedures of AS 3600; or (vi) precast concrete pressure pipes (see AS 1392).This Standard is to apply to concrete structures for storage of liquids where the exposure conditions for concrete are within the specified limits. Such structures include those retaining water or sewage, public swimming pools, and swimming pools the area or overall length of which are greater than specified in AS 2783. However, the specifications of the relevant authority shall be used where applicable.NOTE: The design of a structure or member to which this Standard applies should be carried out by, or under the supervision of, an engineer as specified in AS 3600.
