This European Standard specifies the reference methods used for type testing and in case of dispute, for the determination of particle density and water absorption of normal weight and lightweight aggregates. Other methods may be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. For convenience, some of these other methods are also described in this standard.
The reference methods for normal weight aggregates specified are:
-   a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for railway ballast which uses Annex B);
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the 4 mm test sieve (Clause 8);
-   a pyknometer method for aggregate particles passing the 4 mm test sieve and retained on the 0,063 mm test sieve (Clause 9).
In Clauses 7, 8 and 9, three different particle density parameters (oven-dried particle density, saturated and surface dried particle density and apparent particle density) and water absorption are determined after a soaking period of 24 h. In Annex B, the oven-dried particle density parameter is determined after soaking in water to constant mass.
The wire basket method may be used as an alternative to the pyknometer method for aggregate particles passing the 31, 5 mm test sieve and retained on the 4 mm test sieve. In case of dispute, the pyknometer method described in Clause 8 should be used as the reference method.
NOTE 1   The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve.
NOTE 2   The pyknometer method described in Clause 8 can be used as an alternative for aggregates passing the 4 mm sieve but retained on the 2 mm sieve.
The reference method for lightweight aggregates (Annex C) is a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the 4 mm test sieve. Three different particle density parameters and water absorption are determined after pre-drying and a soaking period of 24 h.
Three other methods for normal weight aggregates can be used to determine the pre-dried particle density:
-   a wire basket method for aggregate particles passing the 63 mm test sieve and retained on the 31,5 mm test sieve (A.3);
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve and retained on the 0,063 mm test sieve (A.4);
-   a pyknometer method for aggregate particles passing the 31,5 mm test sieve, including the 0/0,063 mm size fraction (Annex G).
NOTE 3   If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the pre-dried particle density method as defined in Annex A.
The quick method in Annex E can be used in factory production control to determine the apparent particle density of lightweight aggregates.
Guidance on the significance and use of the various density and water absorption parameters is given in Annex H.

For other purposes, in particular factory production control, other methods may be used provided an appropriate working relationship with the reference method has been established.
This standard is based on the testing of concretes of fixed mix proportions and aggregates of 20 mm maximum size.
NOTE 1   Guidance on the use of larger size is given in Annex A. Precision data is not available for variations in size and for variations in the water content of the test concrete.
NOTE 2   In those cases where the drying shrinkage of a source of coarse aggregate only or a source of fine aggregate (sand) only are required, the other component to be used should be, respectively, a fine or coarse aggregate of known low shrinkage.
NOTE 3   Aggregates with high water demand and/or porosity may in a concrete with a fixed water content result in a mix with insufficient workability to allow full compaction of the test specimens. This is likely to occur with aggregates combinations having a composite water absorption value greater than 3,5% or oven-dried particle densities less than 2,45 Mg/m³ (e.g. for recycled aggregates). In such instances a variation of the method (without precision data) may be carried out by one of the following changes to the concrete mix:
   (a) use of aggregates in the saturated and surface dry condition.
   (b) use of water-reducing admixture.
A note on the details of any modification to the mix design should be included with the test report.

This European Standard specifies a test method which provides information on how an aggregate behaves when it is subjected to the cyclic action of freezing and thawing.
NOTE   The stresses on aggregates due to frost depend, amongst other factors, on the degree of water saturation as well as the rate of cooling.
The results provide a means for assessing an aggregate's resistance to this form of weathering.
The test is applicable to aggregates having a particle size between 4 mm and 63 mm.

This European Standard specifies the procedure for the determination of acid soluble chloride salts which may be present in aggregates. This test is suitable for aggregates where the chloride content does not derive directly from contact with, or immersion in, saline water. Examples of such aggregates are: recycled aggregates containing hydrated cement, where chloride may be bound as calcium chloroaluminates; and some aggregates from desert areas where chloride is occluded within the aggregate particles.

This European Standard specifies the procedure for the determination of the influence of water-soluble components from recycled aggregates on the initial setting time of cement.
NOTE   A procedure is described in EN 1744-1:1998, clause 15.3, for use with natural aggregates; this procedure is intended to demonstrate and quantify the effects of organic contaminators. It is not suitable for recycled aggregates because these may also contain inorganic contaminators.

1   Modification in clause 1 Scope
Amend the existing "NOTE" to read "NOTE 1" and add the following "NOTE 2":
"NOTE 2   For coarse aggregate between 4 mm and 20 mm the percentage of crushed or broken surfaces is linked to the flow coefficient and can therefore be used in association with the test method specified in EN 933-6."
