Tests for thermal and weathering properties of aggregates - Part 1: Determination of resistance to freezing and thawing

This European Standard specifies a test method which provides information on how an aggregate behaves when it is subjected to the cyclic action of freezing and thawing.
NOTE   The stresses on aggregates due to frost depend, amongst other factors, on the degree of water saturation as well as the rate of cooling.
The results provide a means for assessing an aggregate's resistance to this form of weathering.
The test is applicable to aggregates having a particle size between 4 mm and 63 mm.

Diese Europäische Norm legt ein Prüfverfahren fest, das aussagt, wie sich eine Gesteinskörnung verhält, wenn sie zyklischen Frost-Tau-Wechseln ausgesetzt wird.
ANMERKUNG   Die Beanspruchung der Gesteinskörnung infolge von Frost hängt neben weiteren Faktoren sowohl vom Grad der Wassersättigung als auch von der Abkühlgeschwindigkeit ab.
Die Prüfergebnisse ermöglichen es, die Widerstandsfähigkeit einer Gesteinskörnung gegen diese Art der
Witterungsbeanspruchung abzuschätzen.
Diese Prüfung kann auf Gesteinskörnungen mit einer Korngröße zwischen 4 mm und 63 mm angewendet werden.

La présente norme européenne spécifie une méthode d'essai permettant de fournir des données sur le comportement du granulat lorsqu'il est soumis à des cycles de gel-dégel.
NOTE   Les contraintes subies par les granulats en cas de gel dépendent, entre autres facteurs, du degré de saturation en eau et de la vitesse de refroidissement.
Les résultats permettent une évaluation de la résistance du granulat à cette forme d'altération.
L'essai est applicable aux granulats d'une granularité comprise entre 4 mm et 63 mm.

Overview

EN 1367-1:2007 is a European Standard developed by CEN that specifies a standardized test method to evaluate the resistance of aggregates to cyclic freezing and thawing. This process is crucial because aggregates used in construction are often subjected to weathering effects that can degrade their performance and durability. The standard provides a precise methodology to simulate freeze-thaw cycles and assess the physical changes in aggregates, particularly mass loss and strength degradation.

The test is designed for aggregates with particle sizes between 4 mm and 63 mm. It helps quantify the durability of aggregates exposed to frost conditions and provides practical insights for selecting materials suitable for use in climates experiencing freeze-thaw weather.

Key Topics

• Test Principle
  Aggregates are soaked at atmospheric pressure to achieve full water saturation, then subjected to 10 freeze-thaw cycles involving freezing at -17.5 °C under water and thawing at approximately 20 °C.

• Sample Preparation
  Samples must be washed, dried to a constant mass, and prepared in specific size fractions, preferably 8 mm to 16 mm. Sampling and size reduction follow EN 932 standards.

• Freeze-Thaw Cycle Conditions
  The freeze-thaw procedure involves controlled cooling and thawing phases within strict temperature and timing parameters to simulate natural weathering stresses accurately.

• Measurement and Evaluation
  The loss of mass after freeze-thaw cycling is determined by comparing the initial dry mass with the final dry mass of the aggregate retained on a sieve. This percentage loss serves as an indicator of frost resistance.

• Strength Loss Determination (Optional)
  Annex B describes methodologies for assessing strength loss post freeze-thaw cycles by conducting fragmentation tests per EN 1097-2 to provide a comprehensive understanding of aggregate durability.

• Reporting Requirements
  Test reports must include detailed sample information, test results expressed as percentage mass loss, observations of aggregate condition, and testing laboratory credentials.

Applications

EN 1367-1:2007 is fundamental for industries and professionals concerned with the durability and quality of aggregates utilized in:

• Civil Engineering and Construction
  Ensuring that aggregates used in concrete, asphalt, and road bases can withstand freeze-thaw cycles to prevent premature deterioration.

• Pavement Design and Maintenance
  Designing pavements that resist cracking, scaling, and weakening due to seasonal temperature changes.

• Material Quality Control
  Supporting manufacturers and suppliers in verifying the frost resistance of their raw materials for compliance with international durability standards.

• Climate-Resilient Infrastructure Development
  Facilitating the selection of aggregates with proven weathering resistance for projects in regions prone to frost damage.
