AS 2758.0:2020 pdf free.Aggregates and rock for engineering purposes Part 0: Glossary and general series information.
This document sets out essential definitions for aggregates used throughout the AS 2758 Aggregate and rock for engineering purposes series. The document includes a number of informative appendices that may assist in naming rock types and their appearance when crushed. A scheme for identifying unsound stone is appended which may be used if no alternate scheme is provided in contractual documents. Similarly, a sampling scheme is suggested if no sampling scheme for aggregate supply has been included in contract documents.
NOTE 1 Guidance on typical sampling is given in Appendix A.
NOTE 2 InformatIon on aggregate naming, shape and texture is given in Appendix B.
NOTE 3 Recommended limits [or establishing unsound stone are given in Appendix C.
2 Normative references
There are no normative references in this document.
NOTE Documents referenced for informative purposes are listed in the Bibliography.
3 Terms and definitions
For the purposes ot this series, the following terms and definitions apply.
aggregate
granular material produced from crushed rock, gravel, sand, metallurgical slag or reclaimed material, used in in civil construction products and engineering works
3.1.1 coarse aggregate
aggregate in which the majority of particles are retained on a 4.75 mm AS sieve
3.1.2 fine aggregate
aggregate, formed naturally in sand deposits or purpose-made by crushing and processing, in which the majority of particles pass a 4.75 mm AS sieve
Note I to entry: Purpose-made aggregate is known as manufactured sand.
3.1.3 graded aggregate
aggregate in which more than 15 % (by mass) of the total material is retained on at least each of three consecutive sieve sizes in a set
Note I to entry: The typical sieve set used in Australia includes sieves with the following aperture sizes: 75.0
mm, 53.0 mm, 37.5 mm, 26.5 mm, 19.0 mm, 13.2 mm. 9.50 mm, 6.70 mm, 4.75 mm, 2.36 mm, 0.600 mm and 0.075
mm. This selection of sieves is approximately a quarter series.
Note 2 to entry: Crushed rock that consists of a mixture of fine and coarse aggregates, the coarse fraction being graded, is considered a graded aggregate for the purpose of the AS 1141 series.AS 2758.0 pdf download.
