European foreword
This document (EN 13286-41:2021) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2022, and conflicting national standards shall be
withdrawn at the latest by May 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersede EN 13286-41:2003.
The following changes have been made in comparison with EN 13286-41:2003:
— editorial changes;
— to cater for the wide range of strengths possible for hydraulically bound mixtures – from < 1 MPa
to 50 MPa or more - an increase in the permitted ‘time window’ for rupture of the specimen.

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 https://www.iso.org/obp
3.1
hydraulically bound mixture
mixture that hardens by hydraulic and/or pozzolanic and/or sulfatic and/or carbonatic reaction, which
usually has a workability to suit compaction by rolling and which is generally used in bases, sub-bases
and capping layers
3.2
compressive strength
stress at failure of a specimen when tested in uniaxial unconfined compression
3.3
slenderness ratio
ratio of the length to the diameter of a cylindrical specimen
4 Principle
A specimen is subjected to a compressive force until failure. The maximum load sustained by the
specimen is recorded and the compressive strength is calculated.
5 Apparatus
5.1 Compression testing machine
The precision of the machine and the load indication shall be capable of loading and measurement to
accuracy of ± 1 %.
NOTE 1 Test specimens of hydraulically bound mixtures can be either cylindrical or cubical, with nominal
dimensions as small as 50 mm (diameter) and as large as 300 mm (height), and with ultimate compressive
to normal concrete strengths. Machines
