Products and systems for the protection and repair of concrete structures - Test method - Determination of loss of mass of hydrophobic impregnated concrete after freeze-thaw salt stress

This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It specifies a method for determining the loss of mass after freeze-thaw salt stress in sodium chloride solution. It can be used to test the resistance of hydrophobic impregnated concrete as well as the untreated concrete. There are two types of concrete deterioration when a freeze-thaw attack occurs: surface scaling and internal damage.

Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Bestimmung des Masseverlustes von hydrophobiertem Beton nach der Beanspruchung durch Frost-Tausalz-Wechsel

Diese Europäische Norm ist Teil einer Reihe von Normen über Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken. Sie enthält Festlegungen für ein Verfahren zur Bestimmung des Massever-lustes nach Beanspruchung durch Frost-Tausalz-Wechsel in einer Natriumchloridlösung. Das Verfahren ist geeignet für die Prüfung der Beständigkeit von hydrophobiertem sowie unbehandeltem Beton. Bei einem Frost-Tausalz-Angriff sind zwei Arten von Betonschädigungen möglich: oberflächiges Abwittern und innere Schädigun-gen.

Produits et systemes pour la protection et la réparation des structures en béton - Méthode d'essai - Détermination de la perte de masse apres la méthode d'essai de gel-dégel d'un béton hydrofuge

La présente Norme européenne fait partie d'une série traitant des produits et des systèmes destinés à la protection et à la réparation des structures en béton. Elle spécifie une méthode destinée à déterminer la perte de masse après l'épreuve de gel-dégel dans une solution de chlorure de sodium. Elle peut être utilisée pour contrôler la résistance d'un béton imprégné d'hydrofuge ainsi que d'un béton non traité. Il existe deux types de détérioration du béton lorsqu'une attaque de gel-dégel se produit : écaillage de la surface et dégâts internes.

Overview

SIST EN 13581:2002 is a European Standard developed by CEN that specifies a test method for evaluating the durability of hydrophobic impregnated concrete under freeze-thaw salt stress conditions. This standard is part of a series focused on products and systems designed for the protection and repair of concrete structures. It provides a systematic procedure to determine the loss of mass of concrete specimens after exposure to multiple freeze-thaw cycles in a sodium chloride (NaCl) solution.

This standard is critical for assessing the effectiveness of hydrophobic treatments aimed at enhancing the freeze-thaw resistance of concrete surfaces. It addresses two main deterioration types caused by freeze-thaw stress: surface scaling and internal damage, which can significantly affect the structural integrity and longevity of concrete infrastructure exposed to cold climates and deicing salts.

Key Topics

• Scope: Application to hydrophobic impregnated and untreated concrete to measure freeze-thaw salt stress resistance.
• Test Samples: Preparation involves casting concrete cubes (100 x 100 x 100 mm) from a specified concrete mix, curing for 28 days, followed by conditioning under controlled temperature and humidity.
• Treatment: Hydrophobic impregnation is applied by dipping test cube faces in the impregnant, with mass measurements taken before and after treatment to calculate material consumption.
• Freeze-Thaw Cycle: Test cubes are immersed in 3% sodium chloride solution and subjected to 50 freeze-thaw cycles in a controlled temperature environment, simulating realistic freeze-thaw conditions.
• Measurement: Mass loss is measured at 5-cycle intervals, with visual inspections for cracking and surface scaling.
• Results: The change in mass over cycles is graphed to illustrate the deterioration, enabling comparison of treated and untreated specimens.
• Test Report: Comprehensive details including sample preparation, treatment consumption, absorption rates, mass change, visual assessment, graphs, and any deviations from the standard are reported.

Applications

• Concrete Protection Evaluation: SIST EN 13581:2002 provides a reliable test to assess hydrophobic treatments designed to protect concrete from freeze-thaw damage in regions subjected to deicing salts.
• Quality Control: Manufacturers of concrete protective products use this standard to verify product performance before market release.
• Infrastructure Maintenance Planning: Engineers and facility managers can evaluate treated concrete systems for durability, supporting informed maintenance and repair decisions.
• Research and Development: R&D teams benefit from standardized testing procedures to optimize and innovate hydrophobic impregnation technologies.
• Standards Compliance: Ensures that protection and repair treatments meet minimum durability requirements, contributing to safer and longer-lasting concrete structures like bridges, tunnels, parking decks, and highways.

Related Standards

SIST EN 13581:2002 is part of a broader framework of European standards for concrete protection and repair, and it references related standards including:

• EN 1766: Products and systems for the protection and repair of concrete structures - Test methods - Reference concrete for testing. This is used for preparing standardized test cubes in EN 13581.
• Other CEN standards governing the characterization and performance of protective coatings and repair materials for concrete structures.
