Department of State Growth Department of State Growth – January 2021 Section 610 Page 1 of 57 SECTION 610 - STRUCTURAL CONCRETE ##This section cross-references Sections 175, 204, 606, 611, 613, 614, 680, 684, 686, 687, 689, 691, 703 and 801. If any of the above sections are relevant, they should be included in the specification. If any of the above sections are not included in the specification, all references to those sections should be struck out, ensuring that the remaining text is still coherent: 610.01 GENERAL This section specifies the requirements for durability, strength and surface finish for structural concrete including the requirements for mix design, supply and delivery of concrete, sampling and testing, placing, compaction, finishing, curing and protection. Additional requirements for concrete for post-tensioned, pre-tensioned, precast, sprayed concrete and other types of concrete construction are specified in the relevant sections. Requirements for general non-structural concrete paving Works are specified in Section 703. Concrete using general purpose portland cement Type GP or blended cement Type GB shall comply with the requirements of AS 3972 General purpose and blended cements. In addition, blended cement Type GB shall consist of a specified minimum quantity of portland cement in combination with any one or two of Ground Granulated Blast Furnace Slag (Slag), Fly Ash (FA) or Amorphous Silica (AS) and as specified in this section. All concrete shall be special class performance concrete in accordance with Appendix B of AS 1379 Specification and Supply of Concrete and the requirements of this section. Structural concrete shall be designed and constructed in accordance with the requirements of this specification to prevent the occurrence of nonconforming drying shrinkage and cracking, alkali-aggregate reactivity, soluble salts, inadequate cover, curing and compaction and to provide the required protection against exposure to the specified in-service conditions. 610.02 STANDARDS Australian Standards and VicRoads Codes of Practices are referenced in an abbreviated form (e.g. AS 1379 and RC 500.00).
