Full title and description

Products and systems for the protection and repair of concrete structures — Test methods — Part 4: Determination of shrinkage and expansion (EN 12617-4:2002). This part specifies laboratory procedures to measure dimensional stability (shrinkage and expansion) of repair and protection mortars and concretes caused by moisture changes, using both unrestrained and restrained test arrangements.

Abstract

EN 12617-4:2002 provides standardized test methods to quantify length change (shrinkage and expansion) of hydraulic and polymer‑modified hydraulic mortars and concretes (CC and PCC as referenced in EN 1504‑1). Two measurement procedures are described — one for unrestrained (free) movement and one for restrained movement — together with specimen preparation, test conditions, measurement techniques and reporting requirements. The methods are intended to support product assessment, quality control and specification of repair systems for concrete structures.

General information

• Publication date: European publication 1 May 2002; many national adoptions published in 2002 (for example national adoption dates in mid–late 2002).
• Publisher: CEN — European Committee for Standardization (adopted and published by national standards bodies under their national designations such as UNE, DIN, BS, NF, etc.).
• ICS / categories: 91.080.40 (Concrete structures — Test methods for repair and protection products).
• Edition / version: EN 12617-4:2002 (Part 4 of the EN 12617 series).
• Number of pages: Typically 15–18 pages (page count varies slightly between national publications).

Scope

This standard specifies methods to measure dimensional change (shrinkage and expansion) resulting from moisture content variations for hydraulic binders and polymer‑modified hydraulic binders used in mortars and concretes for repair/protection of concrete structures. It applies to grout, mortar and concrete products and systems with a maximum aggregate size up to approximately 10 mm. The procedures include specimen preparation, conditioning, measurement devices, test durations and reporting formats. The standard is intended for product characterization, quality control and to inform specification and design decisions where dimensional stability of repair materials is relevant.

Key topics and requirements

• Definition of the materials covered (hydraulically bound mortars/concretes (CC) and polymer‑modified cement mortars/concretes (PCC), as per EN 1504‑1).
• Two test procedures: unrestrained (free) movement measurement and restrained (constrained) movement measurement.
• Specimen geometry and dimensions, maximum aggregate size limitation (≈10 mm) and mixing/curing instructions to ensure reproducible results.
• Environmental conditioning and monitoring (temperature and relative humidity control during test periods) and recommended test durations.
• Measurement methods: displacement transducers, dial gauges or comparable devices; frequency of readings; calculation of length change as a function of time.
• Presentation and reporting of results (length change vs. time, test conditions, specimen identification and preparation details).
• Notes on applicability and limitations: the standard prescribes test methods but does not itself set acceptance criteria — these must be specified by product standards, contract specifications or regulatory requirements.

Typical use and users

Used by manufacturers of repair mortars and concretes, independent testing laboratories, quality control/assurance teams, material researchers, design engineers and specifiers preparing repair and protection specifications for concrete structures. Typical applications include product development, batch consistency checks, verification against performance specifications and to inform selection of repair products where shrinkage or expansion could affect long‑term performance.
