Abstract - (Show below) - (Hide below)

Proposes requirements for specifying normal-class and special-class concrete and for their manufacture, by either the batch or the continuous production method, for supply in the plastic state, to the customer. Gives performance requirements for the materials and plant used in the manufacturing process, including accuracy of measuring and batch equipment. Criteria for compliance with specified plastic and hardened state properties are also given, together with references to standard methods of testing for these and methods of assessment for compliance with compressive strength criteria. The Appendices cover information to be supplied when specifying special class concrete and methods for determining an acceptable degree of mixing uniformity in different types of mixers.

Scope - (Show below) - (Hide below)

This Standard sets out the minimum requirements for-(a) the materials, plant and equipment used in the supply of concrete;(b) the production and, if applicable, the delivery of concrete in the plastic state;(c) specifying, sampling, testing and compliance with specified properties of plastic and hardened concrete; and(d) the uniformity of mixing.This Standard applies to the supply of all concrete. It is not intended to apply to mortars or grouts.NOTES:1 Requirements for mortars for masonry construction are given in AS 3700 and the methods for sampling and testing mortars in AS 2701.2 Requirements for grouts to be used for the grouting of prestressing tendons in ducts, are given in AS 3600.3 It is not intended that this Standard should take precedence over existing Australian Standards for the manufacture of specific concrete products.4 For additional requirements specified by the customer the applicable contract documents should be consulted.
