Products and systems for the protection and repair of concrete structures - Test methods - Determination of modulus of elasticity in compression

This European Standard specifies two methods for determining the modulus of elasticity in compression for repair products and systems.
Method 1 is for products and systems with high creep characteristics typically those containing polymer binders (PC).
Method 2 is for products and systems with low creep characteristics typically those containing polymer modified (PCC) and cementitious (CC) binders.

Diese Europäische Norm legt zwei Verfahren zur Bestimmung des Elastizitätsmoduls im Druckversuch von Instandsetzungsprodukten und -systemen fest.
Verfahren 1 gilt für Produkte und Systeme mit ausgeprägten Kriecheigenschaften; diese sind üblicherweise diejenigen, die polymere Bindemittel (PC) enthalten.
Verfahren 2 gilt für Produkte und Systeme mit geringen Kriecheigenschaften; diese sind üblicherweise diejenigen, die Bindemittel mit Polymerzusätzen (PCC) oder zementhaltige Bindemittel (CC) enthalten.

La présente Norme européenne spécifie deux méthodes permettant de déterminer le module d’élasticité en compression des produits et systèmes de réparation.
La méthode 1 s’applique aux produits et systèmes à déformation de fluage élevée, typiquement ceux contenant des liants polymères (PC).
La méthode 2 s’applique aux produits et systèmes à faible déformation de fluage, typiquement les mortiers hydrauliques (CC) et les mortiers hydrauliques modifiés par l’ajout de polymère (PCC).

Overview

SIST EN 13412:2006 is a European Standard developed by CEN that defines test methods for determining the modulus of elasticity in compression of repair products and systems used in concrete structures. This standard is critical for assessing the mechanical performance of materials designed for the protection and repair of concrete, ensuring their reliability and effectiveness in structural applications.

The standard specifies two distinct testing methods tailored for different types of repair products based on their creep characteristics:

• Method 1: For products and systems with high creep characteristics, typically containing polymer binders (PC).
• Method 2: For products and systems with low creep characteristics, typically containing polymer-modified (PCC) or cementitious (CC) binders.

This test plays a vital role in evaluating the elastic properties and durability of repair mortars and coatings, guiding manufacturers, engineers, and quality control professionals in the construction and refurbishment of concrete structures.

Key Topics

• Scope and Application: SIST EN 13412:2006 focuses exclusively on determining the secant modulus of elasticity in compression for concrete repair materials, underpinning quality assurance in structural repair systems.

• Test Specimens Preparation: The standard outlines precise methods for mixing, molding (40 mm × 40 mm × 160 mm prisms), curing, and conditioning test specimens under controlled laboratory climates as per Annex A.

• Test Methods:

  • Method 1 involves a rapid loading rate to counteract creep effects in polymer-based repair materials.
  • Method 2 applies lower loading rates suitable for cementitious and polymer-modified products with minimal creep.

• Equipment and Instrumentation: Includes requirements for mortar mixers, compression testing machines compliant with EN 12390-4, and strain gauges capable of sensitive and continuous strain measurement.

• Measurement Process: Accurate strain measurement aligned parallel to the prism axis ensures valid determination of compressive strain under controlled stress levels.

• Calculation of Modulus: The secant modulus is derived from the ratio of applied compressive stress to the measured strain, averaged across multiple specimens for accuracy.

Applications

SIST EN 13412:2006 is widely used to ensure the structural integrity and longevity of concrete repair materials, including:

• Structural Repairs: Assessing the elastic modulus in compression helps in selecting appropriate repair mortars and coatings to restore or enhance load-bearing capacity in damaged concrete structures.

• Quality Control: Manufacturers use this standard to verify consistency and compliance with performance requirements before market release.

• Design Validation: Engineers rely on standardized modulus values to accurately model repaired structures for safety and serviceability.

• Research and Development: Material scientists and product developers apply these test methods to innovate and improve repair products with optimized mechanical properties.

This standard supports harmonized testing protocols across Europe, facilitating mutual recognition of test results and regulatory compliance for construction materials.
