European foreword
This document (prEN 1744-4:2020) has been prepared by Technical Committee CEN/TC 154
“Aggregates”, the secretariat of which is held by BSI.This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1744-4:2005.
The main changes compared to EN 1744-4:2005 are:
— updated normative references;
— clarification of the apparatus described in 5.2;
— clarification of the procedure described in 5.5.
This document forms part of a series of tests for chemical properties of aggregates. Test
methods for other properties of aggregates are covered by Parts of the following European
standards:EN 932, Tests for general properties of aggregates
EN 933, Tests for geometrical properties of aggregates
EN 1097, Tests for mechanical and physical properties of aggregates
EN 1367, Tests for thermal and weathering properties of aggregates
EN 13179, Tests for filler aggregate used in bituminous mixtures
The other parts of EN 1744 are, or will be:
Part 1: Chemical analysis
Part 2: Determination of resistance to alkali/aggregate reaction
Part 3: Preparation of eluates by leaching of aggregates
Part 5: Determination of acid soluble chloride salts
Part 6: Determination of the influence of aggregate extract on the initial setting time of cement

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at http://www.iso.org/obp
3.1
filler aggregate
aggregate, most of which passes a 0,063 mm sieve, which can be added to construction
materials to provide certain properties3.2
water susceptibility of filler
measure of the degree of separation which occurs in the presence of water from a filler bitumen
mixture, e.g. as a result of intra-crystalline water inclusion between aggregate particles and
binder coating3.3
subsample
sample obtained from sampling increments or a bulk sample by means of a sample reduction
procedure3.4
test portion
sample used as a whole in a single test
3.5
aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D
Note 1 to entry: This designation accepts the presence of some particles which will be retained on the
upper sieve (oversize) and some which will pass the lower sieve (undersize).3.6
particle size fraction
fraction of an aggregate passing the larger of two sieves and retained on the smaller
Note 1 to entry: The smaller sieve size can be zero.3.7
constant mass
successive weighings after drying at least 1 h apart not differing by more than 0,1 %, by mass
Note 1 to entry: In many cases constant mass can be achieved after a test portion has been dried for a
pre- determined period in a specified oven at (110 ± 5) °C. Test laboratories can determine the time
required to achieve constant mass for specific types and sizes of sample dependent upon the drying
capacity of the oven used.---------------------- Page: 7 ----------------------

4 Principle
A mixture of filler and bitumen is stirred in hot water. If filler becomes separated from the
mixture (indicated by the turbidity of the water), the filler is recovered on a filter paper and
weighed.5 Separation of filler from a bitumen filler mixture
