Testing the freeze-thaw resistance of concrete - Internal structural damage
This document specifies three test methods for the estimation of the freeze-thaw resistance of concrete with regard to internal structural damage. It can be used either to compare new constituents or new concrete compositions against a constituent or a concrete composition that is known to give adequate performance in the local environment or to assess the test results against some absolute numerical values based on local experiences.
Extrapolation of test results to assess different concrete i.e. new constituents or new concrete compositions requires an expert evaluation.
NOTE Specification based on these test methods should take into account the behaviour of concrete under practical conditions.
There is no established correlation between the results obtained by the three test methods. All tests will clearly identify poor and good behaviour, but they differ in their assessment of marginal behaviour.
Prüfung des Frost-Tauwiderstandes von Beton - Innere Gefügestörung
Dieses Dokument beschreibt drei Prüfverfahren zur Abschätzung des Frost-Tauwiderstandes von Beton hinsichtlich der inneren Gefügestörung. Es kann angewendet werden, um neue Ausgangsstoffe oder neue Betonzusammensetzungen mit bekannten Ausgangsstoffen oder Betonzusammensetzungen, mit denen in der örtlichen Umgebung ein ausreichendes Verhalten sichergestellt wird, zu vergleichen oder um die Prüfergebnisse mit Grenzwerten, die auf örtlichen Erfahrungen basieren, zu vergleichen und zu bewerten.
Die Extrapolation der Prüfergebnisse zur Bewertung verschiedener Betonarten, d.h. mit neuen Bestandteilen oder mit einer neuen Zusammensetzung, ist von einem Fachmann zu bewerten.
ANMERKUNG Die Festlegung von Beton auf der Grundlage dieser drei Prüfverfahren sollte das Verhalten des Betons unter praktischen Bedingungen berücksichtigen.
Es gibt keine feststehende Korrelation zwischen den Ergebnissen aus den drei Prüfverfahren. Alle Prüfverfahren ermöglichen die deutliche Unterscheidung zwischen schlechtem und gutem Verhalten. Sie unterscheiden sich jedoch in der Bewertung des Verhaltens in Grenzfällen.

Foreword
This document (CEN/TR 15177:2006) has been prepared jointly by Technical Committee CEN/TC 51
"Cement and building limes", the secretariat of which is held by IBN/BIN and by Technical Committee CEN/TC
104 "Concrete and related products", the secretariat of which is held by DIN.
No existing European Standard is superseded.
It is based on the Austrian Standard ÖNORM B 3303 "Testing of Concrete" and on the RILEM
recommendation "Test methods of frost resistance of concrete" of RILEM TC 176 IDC. These tests have since
been developed by individual countries. This document takes into account those developments.

Introduction
Concrete structures exposed to the effects of freezing and thawing need to be durable, to have an adequate
resistance to this action and, in cases such as road construction, to freezing and thawing in the presence of
de-icing agents. It is desirable, especially in the case of new constituents or new concrete compositions, to
test for such properties. This also applies to concrete mixes, concrete products, precast concrete, concrete
elements or concrete in situ.
Many different test methods have been developed. No single test met
