Admixtures for concrete, mortar and grout - Part 3: Admixtures for masonry mortar - Definitions, requirements, conformity and marking and labelling

This European Standard defines and specifies the requirements and conformity criteria for admixtures for use in cement based masonry mortar.
It covers two types of admixtures, long term retarding and air entraining/plasticising which are used in ready-mixed and site made masonry mortars.
Provisions for the use of admixtures for masonry mortar are not part of this European Standard but are covered by EN 998-1 and EN 998-2.

Overview

SIST EN 934-3:2009/kFprA1:2012 is a European Standard developed by CEN that defines the essential requirements, conformity criteria, and marking and labelling specifications for admixtures used in cement-based masonry mortar. This standard addresses the quality and performance criteria for two primary types of admixtures: long-term retarding admixtures and air entraining/plasticising admixtures. It applies to admixtures used in both ready-mixed and site-made masonry mortars, ensuring consistent quality and reliability across construction projects within the European market. The standard aligns with relevant clauses from EN 934-6 for sampling and conformity control but deliberately excludes provisions on the use of these admixtures, which are covered under EN 998-1 and EN 998-2.

Key Topics

• Definitions and Requirements: Establishes clear terminology for admixtures in masonry mortar and outlines mandatory performance characteristics.
• Types of Admixtures Covered:
  • Long-Term Retarding: Extends workability time of mortar for improved site performance.
  • Air Entraining/Plasticising: Enhances mortar workability and durability by incorporating and stabilizing air voids.
• Conformity Criteria: Specifies procedures for compliance verification including sampling, testing, and evaluation, primarily referencing EN 934-6:2001 and its amendment EN 934-6:2001/A1:2005.
• Marking and Labelling: Mandates standardized labelling for transparency and traceability, facilitating safe and informed use on site.
• Modifications and Amendments: The 2011 draft amendment refines clause references and removes outdated normative references to enhance clarity and maintain alignment with current testing standards.

Applications

• Construction Industry: Used by manufacturers and suppliers of masonry mortars to ensure their admixtures comply with stringent European standards enhancing the quality and durability of masonry work.
• Ready-Mixed and Site-Made Mortars: Provides quality assurance for admixtures employed both in factory-mixed mortars and mortars mixed on-site, ensuring consistent performance regardless of production method.
• Architects and Engineers: Helps specify appropriate admixtures with performance guarantees, supporting durable masonry structures.
• Quality Control Labs: Offers procedural guidance for sampling, conformity control, and evaluation to verify admixture compliance with European regulations.
• Regulatory Compliance: Assists national standard bodies and construction authorities in enforcing standardized admixture use aligned with European norms.

Related Standards

• EN 934-6:2001 and EN 934-6:2001/A1:2005: Provide detailed procedures for sampling, conformity control, and evaluation essential for compliance assessment under EN 934-3.
• EN 998-1 & EN 998-2: Cover provisions related to the application and use of admixtures in masonry mortar, complementing the scope of EN 934-3.
• EN 934 Series: A comprehensive set of standards for admixtures used in concrete, mortar, and grout, ensuring harmonized testing methods and quality requirements across related construction products.
• CEN/TC 104 Technical Committee: Responsible for development and maintenance of standards related to concrete and related products, ensuring up-to-date industry relevance.

By adhering to SIST EN 934-3:2009/kFprA1:2012, stakeholders benefit from harmonized definitions, robust requirements, and conformity protocols that support high-quality masonry construction across Europe. This standard promotes durability, workability, and safety in cement-based masonry mortars enhanced by regulated admixtures.
