Methods of test for mortar - Part 14: Determination of durability of hardened masonry mortars (with cement comprising greater than 50% of the total binder mass)

This European Standard specifies a laboratory method of test under onerous conditions for determining the durability of masonry mortars containing mineral binders, with cement comprising greater than 50% of the total binder mass, and normal, as well as lightweight aggregates. The method may also be applicable to mortar beds taken from existing structures.

Prüfverfahren für Mörtel für Mauerwerk - Teil 14: Bestimmung der Dauerhaftigkeit von erhärtetem Mauermörtel (Festmörtel) (mit einem Zementanteil an der Gesamtbindemittelmenge von mehr als 50%)

Diese Europäische Norm legt ein Laborverfahren zur Bestimmung der Dauerhaftigkeit von Mauermörteln mit mineralischen Bindemitteln, deren Zementanteil an der Gesamtbindemittelmenge mehr als 50 % beträgt und die sowohl Normal- als auch Leichtzuschläge enthalten, unter verschärften Prüfbedingungen fest. Das Verfahren darf auch für Lagerfugenmörtel angewendet werden, die bestehenden Bauwerken entnommen werden.

Méthodes d'essai des mortiers - Partie 14: Détermination de la durabilité du mortier durci (avec du ciment comportant plus de 50% de la masse totale de liant)

La présente norme européenne décrit une méthode d'essai permettant, dans des conditions sévères, de  déterminer la durabilité des mortiers pour maçonnerie à base de liants hydrauliques (minéraux dans les autres normes d'essais) constitués pour plus de 50 % en masse de ciment et contenant des granulats lourds et/ou légers. Cette méthode est applicable également aux lits de mortiers prélevés sur des ouvrages existants.

Overview

prEN 1015-14 is a CEN laboratory test method for assessing the durability of hardened masonry mortars where cement comprises greater than 50% of the total binder mass. The standard defines an onerous (severe) laboratory procedure to evaluate how cement-bound mortars - including mixes with normal and lightweight aggregates - resist deterioration. It also notes possible applicability to mortar beds sampled from existing structures.

Key topics

  • Scope and applicability: Mortars with mineral binders and a cement content exceeding 50% of the binder mass; both normal and lightweight aggregates are covered.
  • Laboratory method: A standardized, severe test regime intended to simulate aggressive conditions to assess long-term performance (accelerated durability testing).
  • Specimens and sampling: Procedures for using hardened mortar specimens and, where relevant, mortar beds taken from existing construction.
  • Durability assessment: Evaluation of deterioration under the prescribed test conditions to judge suitability for masonry applications.
  • Standards context: Part of the prEN 1015 series (Methods of test for mortar), focused specifically on durability of hardened masonry mortars.

Applications

prEN 1015-14 is practical for professionals involved in mortar design, quality assurance, and building conservation:

  • Materials and mortar manufacturers - to evaluate performance of cement-rich mortar formulations and optimize mixes for durability.
  • Testing laboratories - to perform standardized laboratory durability tests and provide comparable results.
  • Structural and conservation engineers - to assess existing mortar beds and specify durable repair mortars for masonry restoration.
  • Contractors and specifiers - to select mortars suitable for demanding exposure conditions or for use with lightweight aggregates.
  • Certification and compliance bodies - to support conformity assessment and technical documentation related to mortar durability.

Related standards

  • prEN 1015 series - other parts covering methods of test for mortar (sampling, physical and mechanical testing).
  • Other masonry and mortar standards (national and European) for performance, composition and specification - consult relevant standards for complementary requirements.
