ISO 14824-1:2012(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14824-1 was prepared by Technical Committee ISO/TC 71, Concrete, reinforced concrete and pre-
stressed concrete, Subcommittee SC 3, Concrete production and execution of concrete structures.
ISO 14824 consists of the following parts, under the general title Grout for prestressing tendons:
— Part 1: Basic requirements
— Part 2: Grouting procedures
— Part 3: Test methods

ISO 14824-1:2012(E)
Introduction
In post-tensioned prestressed concrete construction, the grouting of tendons is an important operation.
The intention of this part of ISO 14824 is to provide basic requirements for the approval of cement
grouts, compliance with which will satisfy the requirements in ISO 22966.
The main function of grouting is to:
— protect the prestressing steel against corrosion;
— provide a bond between the prestressing steel and the ducts where required for the design of
the structure;
— allow transfer of compressive stresses in the structure in a direction transverse to internal tendons;
— fill all voids where water may accumulate and cause frost damage.
The testing regimes anticipated by this part of ISO 14824 include three levels:
(1) initial type and audit testing in accordance with this part of ISO 14824;
(2) suitability testing for confirmation of the selected grout for a specific project in accordance with
ISO 14824-2;
(3) inspection during grouting works on a specific project in accordance with ISO 14824-2.
The test methods for each of the regimes are given in ISO 14824-3.
In some countries requirements exist for independent third-party certification of grout and grouting
procedures which should be set out in national requirements to supplement ISO 22966.
Certain special structures or tendon configurations can require grouts with enhanced performance.
Any resulting necessary amendment of the requirements of this part of ISO 14824 needs to be included
in the execution specification.
