Aggregates for construction works - Part 1: Characteristics

The Part 1 (harmonised) European Standard will specify the characteristics of aggregates for use in
•   concrete for buildings, roads and other civil engineering works,
•   mortar
•   bituminous mixtures and surface treatments for roads, airfields and other trafficked areas,
•   unbound and hydraulically bound materials for use in civil engineering work and road construction
Aggregates to be covered in this European Standard, are obtained by processing natural, manufactured or recycled materials and mixtures of these materials. Families of aggregates covered will include coarse aggregates, grit, fine aggregates, natural graded aggregates, all-in aggregates and added fillers.
The standard will cover natural and manufactured aggregates having an oven dried particle density greater than 2,00 Mg/m3 and recycled aggregates with particle densities greater than 1,50 Mg/m3. Natural and manufactured aggregates of density less than or equal to 2,00 Mg/m3 are already covered by our existing standard EN 13055.
The standard will not cover
•   the use of reclaimed bituminous mixtures. Reclaimed asphalt for use as a constituent of bituminous mixtures is specified in EN 13108 8.
•   use of aggregates as soil
•   the creation of unbound mixtures for road construction from aggregates as this aspect is specified in EN13285
The non-harmonised Part 2 standard will provide non-contradictory complementary information to assist in the practical application of the Part 1 standard, including advice on the reasons for testing and declaring various characteristics and recommendations for the practical implementation of factory production control measures.

Overview

The European Standard prEN 17555-1, titled Aggregates for Construction Works - Part 1: Characteristics, is developed by CEN to specify the key characteristics of aggregates used in various construction applications. This harmonised standard covers natural, manufactured, and recycled aggregates, including various aggregate families such as coarse aggregates, grit, fine aggregates, natural graded aggregates, all-in aggregates, and added fillers. It applies to aggregates with oven-dried particle densities above 2.00 Mg/m³ for natural and manufactured types, and above 1.50 Mg/m³ for recycled materials.

This standard is essential for ensuring consistent quality and performance in aggregates intended for:

• Concrete in buildings, roads, and civil engineering
• Mortar applications
• Bituminous mixtures and surface treatments for traffic areas including roads and airfields
• Unbound and hydraulically bound materials in road and civil engineering construction

prEN 17555-1 replaces several earlier standards, streamlining terminology, testing, and classification to support better harmonisation across Europe.

Key Topics

• Aggregate Types and Definitions: Includes coarse and fine aggregates, grit, natural graded, all-in aggregates, and various types of added fillers (natural, manufactured, mixed, composite, and recycled).
• Particle Properties: Focus on particle size, shape, density, percentage of crushed particles, and cleanliness to ensure optimal performance.
• Mechanical and Durability Characteristics:
  • Resistance to fragmentation, wear, polishing, abrasion, attrition, and thermal shock.
  • Volume stability and resistance to weathering, including freeze-thaw resistance.
  • Water absorption, durability, and chemical characteristics such as sulfate and sulfur content.
• Testing Protocols: Specifies standardized sampling methods and test methods for assessing aggregate properties like methylene blue value, carbonate content, and resistance tests.
• Factory Production Control (FPC): Guidelines for ongoing quality control, initial inspections, and continuous monitoring to ensure the reliability of aggregate production.
• Marking, Labelling, and Packaging: Ensures traceability and information transparency throughout the supply chain.

Notably, the standard excludes the use of reclaimed bituminous mixtures, soil aggregates, armourstone, railway ballast, and aggregates for earthworks, which are covered under other European standards.

Applications

prEN 17555-1 aggregates are fundamental materials in multiple construction sectors:

• Concrete Production: Ensures the performance of structural and non-structural concrete for buildings, bridges, highways, and civil infrastructure.
• Mortar and Plasters: Used in masonry mortar, floor screeds, wall renders, repair mortars, and grouts, requiring precise aggregate characteristics for workability and strength.
• Road Construction: Critical for bituminous mixtures, surface treatments, base and sub-base layers, and sprayed asphalt surfaces on roads and airfields.
• Civil Engineering Works: Suitable for hydraulically bound mixtures and unbound road construction materials, ensuring stability and longevity.

Aggregates that comply with this standard contribute to improved construction quality, durability, safety, and environmental sustainability by integrating both natural and recycled materials within a regulated framework.

Related Standards

• prEN 13055-1:2021: Lightweight aggregates with lower density than those covered in prEN 17555-1.
• prEN 13383-1:2021: Armourstone characteristics for use in hydraulic engineering.
• prEN 13450-1:2021: Aggregates for railway ballast.
• EN 13108-8:2016: Reclaimed asphalt aggregates used in bituminous mixtures.
• EN 16907-2:2018: Aggregates used in earthworks.
• Test Method Standards: Including EN 933 series (geometrical properties), EN 1097 series (mechanical and physical properties), and others for specific chemical and mechanical tests.

This suite of standards collectively ensures the comprehensive assessment and specification of construction aggregates, supporting regulatory compliance, quality assurance, and enhanced construction performance.

— EN 13043:2002, together with EN 13043:2002/AC:2004,
— EN 13139:2002, together with EN 13139:2002/AC:2004, and
— EN 13242:2002+A1:2007.
The most significant technical changes compared to EN 12620:2002+A1:2008, EN 13043:2002,
together with EN 13043:2002/AC:2004, EN 13139:2002, together with EN 13139:2002/AC:2004, and
EN 13242:2002+A1:2007 include:
a) unification and clarifications of the scope statement;
b) unification and improvement of definitions for aggregate families and other matters which were
common across the four main aggregate standards EN 12620, EN 13043, EN 13139 and EN 13242,
i.e. for coarse, fine, all-in aggregates, natural graded aggregates, grit and added fillers;
c) updating and improving references to supporting test methods;
d) consolidation of classes for characteristics, including:
a. merging of classes which were common across the four main aggregate standards: EN 12620,
EN 13043, EN 13139 and EN 13242;
b. addition of classes to respond to requests from Member States;
c. addition of intermediate classes to provide a more uniform sequence;
e) with regard to aggregates (not including added filler):
a. unification of overall limits for graded coarse aggregates at mid-size sieves;
b. removal of clauses referring to tolerances on grading;
c. deletion of classes (and replacement with a simple level declaration) for proportions of

4.1.3.2 Harmful fines
4.1.3.2.1 General
The harmfulness of fines of fine aggregates, all-in aggregates and natural-graded aggregates may be
determined using two different proxy characteristics: the sand-equivalent value and the methylene
blue value. The “sand equivalent” test quantifies the relative proportions of fine dust or clay-like
materials in fine aggregate by forcing the fine particles into suspension using a flocculating agent.
However, the sand equivalent test does not quantify the deleterious adsorbing effect of the fine dust or
clay-like minerals, which varies from one mineral to another. This is achieved instead by the
methylene blue test which is based on the degree of adsorption of a dye solution of methylene blue by
the particles of clay contained in a 0/2 mm fine aggregate.
4.1.3.2.2 Sand equivalent test
4.1.3.2.2.1 General
There are two methods in EN 933-8:2012+A1:2015 for determining sand equivalent value for fine
aggregates, all-in aggregates and natural graded aggregates: SE and SE . The SE method is carried
10 4 10
out on the 0/2 mm size fraction and the SE method is carried out on the 0/4 mm size fraction. The
SE method shall be the reference method.
4.1.3.2.2.2 Sand equivalent SE method
The sand equivalent SE of fine aggregate, all-in aggregate and natural graded aggregate shall be
assessed, either:
a) without testing (WT), if the performance of fines content of these aggregates is declared, based on
the assessment according to 4.1.3.1, and the value determined therein is < 3 % (by mass); or
b) based on determination of the sand equivalent SE10 in accordance with EN 933-8:2012+A1:2015,
Clause 8.
In case b) the results obtained shall be evaluated against the criterion for the respective class in
Table 11.
The performance shall be expressed as a
