Products and systems for the protection and repair of concrete structures - Test methods - Determination of workability - Part 3: Test for flow of repair concrete

Normal workability concrete mixes, which can include proprietary formulations, are applied and compacted in accordance with conventional practice. The workability of these products should be assessed using the slump, VeBe or other appropriate method given in EN 206-1. The workability of conventional high flow concrete mixes should be assessed by the method of EN 12358.

Anwendungsbereich
Betonmischungen mit üblicher Verarbeitbarkeit, zu denen auch Fertigmischungen gehören können, werden nach der üblichen Praxis angewendet und verdichtet. Die Verarbeitbarkeit dieser Produkte sollte durch das Slump-, das Vebe- oder ein anderes geeignetes Verfahren nach EN 206-1 nachgewiesen werden. Die Verarbeitbarkeit von konventionellen freifließenden Betonmischungen sollte nach dem Verfahren von EN 12358 nachgewiesen werden.

Les bétons qui ont une ouvrabilité normale, et dont certains peuvent avoir une formulation brevetée, sont appliqués et compactés suivant la pratique conventionnelle. Il convient d'évaluer l'ouvrabilité de ces produits par l'essai d'affaissement, l'essai Vébé ou selon toute autre méthode appropriée indiquée dans l'EN 206-1. Il convient d'évaluer l'ouvrabilité des mélanges conventionnels de béton à haute fluidité conformément à la méthode donnée dans l'EN 12358.

Overview

EN 13395-3:2002 is a European Standard developed by CEN that specifies test methods for evaluating the workability of repair concrete used in the protection and repair of concrete structures. This part 3 of the series focuses specifically on the test for flow of repair concrete. The standard provides a reliable laboratory method to assess the flowability of high-performance repair concrete mixes, ensuring that these mixes meet practical requirements for ease of application and compaction on-site.

The standard addresses concrete mixes with normal workability, including proprietary formulations, mainly those that are unsuitable for conventional slump or VeBe tests but require specialized flow testing to ensure effective repair applications. EN 13395-3:2002 harmonizes quality control practices across Europe by defining precise test procedures and equipment specifications for assessing flow performance.

Key Topics

• Scope & Applicability: Applies to normal and proprietary repair concrete mixes with normal workability, including those with maximum aggregate sizes up to 10 mm and high flow characteristics. Normal flow concretes are evaluated through traditional methods (EN 206-1 or EN 12358), while highly flowable repair concrete requires this flow test.

• Test Principle: Measures the time required for a fixed volume of repair concrete to flow 750 mm along a horizontal trough, representing the material's flowability under laboratory conditions.

• Test Equipment: Includes a specially designed flow trough and funnel made of galvanised steel, a concrete mixer conforming to EN 206-1, measuring jugs, and controlled climate conditions to simulate typical site or environmental conditions.

• Test Procedure: Concrete is mixed and conditioned at standard or specified temperatures, poured into the funnel, and released onto the trough. The flow time and maximum distance flowed are recorded, with repeated tests at various intervals post-mixing for accuracy.

• Reporting Requirements: Detailed test reports include test method references, laboratory and product identification, test conditions, equipment calibration, flow time results, observations of segregation or bleeding, and precision data, ensuring traceability and quality control.

Applications

EN 13395-3:2002 is essential for:

• Quality Control of Repair Concrete: Ensures repair concrete products meet specific workability parameters for optimal application and performance on site.

• Site Laboratory Testing: Provides a simple, robust, and replicable test method suitable for on-site labs, enabling contractors and manufacturers to monitor concrete flow during repair works.

• Research and Development: Allows manufacturers to develop and validate new repair concrete formulations with appropriate flow characteristics that align with European standards.

• Compliance and Certification: Supports compliance with European standards for concrete repair products, facilitating market acceptance and regulatory approval.

• Durable Concrete Repairs: Accurate flow testing helps avoid issues such as poor compaction, segregation, or insufficient filling, enhancing the longevity and structural integrity of repaired concrete structures.

Related Standards

• EN 13395-2: Test for flow of grout or mortar - covers lower flow materials for repair.
• EN 13395-4: Application testing for mortar overhead - evaluates workability during application in non-horizontal orientations.
• EN 206-1: Specification and conformity of concrete - provides general testing guidelines including slump and VeBe methods.
• EN 12358: Test methods for consistency of concrete - relevant for conventional high flow concrete mixes.
• EN 1504-1: Definitions, requirements, and quality control for protection and repair products - includes terminology used across the repair standards series.
