Foreword
This document EN 13294:2002 has been prepared by Technical Committee CEN/TC 104 "Concrete and related
products", the secretariat of which is held by DIN.
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by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest
by December 2002.
It has been prepared by sub-committee 8 "Products and systems for the protection and repair of concrete
structures", the secretariat of which is held by AFNOR.
This European Standard is one of a series dealing with products and systems for the protection and repair of
concrete structures. It describes a method of test determining the stiffening time of grout, mortar or concrete repair
products and systems, making allowance for the presence of coarse aggregate.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies a method for determining the stiffening time of repair products and systems

specified in prEN 1504-3 comprising hydraulic based mortar and concrete (CC), including those modified by the
addition of polymers (PCC).
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Principle
The method shall be based on EN 480-2. A sample of freshly-mixed repair product is placed into a container set on
a weigh balance. Periodically, a penetration rod is pressed into the mortar to a defined depth and the penetration
resistance calculated from the mass reading on the scale. As the mortar stiffens due to hydration of the
cementitious components, the resistance to penetration will increase and by recording the penetration resistance
with time, the stiffening time can be determined.
The stiffening time is the period from completion of mixing of the grout, mortar or concrete until a resistance to

penetration of 0,5 N/mm
