-   normal-weight, heavy-weight and light-weight;
-   mixed on site, ready-mixed or produced in a plant for precast concrete products;
-   compacted or self-compacting to retain no appreciable amount of entrapped air other than entrained air.
(3) This standard specifies requirements for:
-   the constituents of concrete;
-   the properties of fresh and hardened concrete and their verification;
-   the limitations for concrete composition;
-   the specification of concrete;
-   the delivery of fresh concrete;
-   the production control procedures;
-   the conformity criteria and evaluation of conformity.
(4) Other European Standards for specific products e.g. precast products or for processes within the field of the scope of this standard may require or permit deviations.
(5) Additional or different requirements may be given for specific applications in other European Standards, for example:
-   concrete to be used in roads and other trafficked areas (e.g. concrete pavements according to EN 13877-1);
-   special technologies (e.g. sprayed concrete according to EN 14487).
(6) Supplementing requirements or different testing procedures may be specified for specific types of concrete and applications, for example:
-   concrete for massive structures (e.g. dams);
-   dry mixed concrete;
-   concrete with a Dmax of 4 mm or less (mortar);
-   self-compacting concretes (SCC) containing lightweight or heavy-weight aggregates or fibres;

This document describes the procedure for obtaining the non-steady-state chloride migration coefficient of specimens of hardened concrete at a specified age. The test procedure does not take into account any interaction of concrete with the saline solution over time. The test result is a durability indicator with respect to the resistance of the concrete investigated against chloride penetration.
The test procedure does not apply to concrete specimens with surface treatments such as silanes.
If the aggregate is electrically conductive or porous this will influence the magnitude of chloride migration. This fact has to be taken into account when establishing threshold values. It prevents comparison of chloride migration values between concretes if the aggregates show a difference of half an order of magnitude (higher or lower) of chloride migration.
Similar influence may be seen when metallic or electrically conducting fibres or particles are present.

This Technical Report explains the reasoning behind the requirements and procedures given in EN 13791 [1] and why some concepts and procedures given in EN 13791:2007 [2] were not adopted in the 2017 revision. The annex comprises worked examples of the procedures given in EN 13791.

This procedure is a method for evaluating the carbonation resistance of concrete using test conditions that accelerate the rate of carbonation. After a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide.
NOTE   The test under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to conditioning of 28 days, a minimum conditioning period of 14 days and an exposure to increased carbon dioxide levels of 70 days.
This procedure is not a method for the determination of carbonation depths in existing concrete structures.

This document specifies the requirements for the performance of compression testing machines for the measurement of the compressive strength of concrete.

This document specifies the procedure for the determination of total shrinkage of concrete specimens in drying conditions.
NOTE 1   Possible shrinkage or length changes occurring before 24 h of age, and which may have significant amplitude and/or consequences, e.g. for high performance concrete and/or in case of restraint, may need to be measured according to a complementary procedure not covered by the present standard.
NOTE 2   Information on a simplified procedure for the determination of autogenous shrinkage is given in Annex A.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.

This document describes the procedure for determining the creep (total, autogenous (basic) and drying) of hardened concrete test specimens subjected to a sustained longitudinal compressive load.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.

It differentiates between hardened concrete in the following states:
1) as-received;
2) water saturated;
3) oven-dried.
The mass and volume of the specimen of hardened concrete are determined and the density calculated.

This European Standard specifies a method for the determination of the compressive strength of test
specimens of hardened concrete.

(1)   This European Standard:
-   gives methods and procedures for the estimation of the in-situ compressive strength and characteristic in-situ compressive strength of concrete in structures and precast concrete components using direct methods (core testing) and indirect methods, e.g. ultra-sonic pulse velocity, rebound number;
-   provides principles and guidance for establishing the relationships between test results from indirect test methods and the in-situ compressive strength;
-   provides procedures and guidance on in-situ assessment of the compressive strength class of concrete where there is doubt over the strength of concrete recently supplied to a structure or precast concrete component.
This European Standard does not include the following cases:
-   assessment based on cores less than 50 mm in diameter, micro-cores;
-   assessment of the quality of concrete for properties other than compressive strength, e.g. durability-related properties;
-   specific provisions for lightweight concretes;
-   use of pull-out testing;
-   in the Clause 8 procedures, provisions for less than 8 cores without indirect testing;
-   use of comparative testing (see CEN/TR Further guidance on the application of EN 13791:2016 and background to the provisions [1] for explanation).
(2)   This European Standard is not for the assessment of conformity of concrete compressive strength in accordance with EN 206 or EN 13369 except as indicated in EN 206:2013, 5.5.1.2 or 8.4.

This European standard specifies a method for determining the density of compacted fresh concrete both in the laboratory and in the field.
NOTE   It may not be applicable to very stiff concrete which cannot be compacted by normal vibration.

This European Standard describes two methods for determination of air content of compacted fresh concrete, made with normal weight or relatively dense aggregate and having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm.
The test is not suitable for concretes with slumps less than 10 mm.
NOTE    Neither method is applicable to concretes made with lightweight aggregates, air cooled blast-furnace slag, or aggregates with high porosity, because of the magnitude of the aggregate correction factor, compared with the entrained air content of the concrete.

This European standard specifies a method for determining the consistence of fresh concrete by the
slump test.
The slump test is sensitive to changes in the consistence of concrete, which correspond to slumps
between 10 mm and 210 mm. Beyond these extremes the measurement of slump can be unsuitable and
other methods of determining the consistency should be considered.
If the slump continues to change over a period of 1 min after withdrawing of the cone, the slump test is
not suitable as a measure of consistence.
The test is not suitable when the declared value of D of the coarsest fraction of aggregates actually used
in the concrete (Dmax) is greater than 40 mm.

This European standard specifies a method for determining the flow of fresh concrete. It is not applicable to self-compacting concrete, foamed concrete, no-fines concrete, or for concrete having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) of greater than 63 mm.
NOTE   The flow test is sensitive to changes in the consistency of concrete, which correspond to flow values between 340 mm and 620 mm. Beyond these extremes the flow table test may be unsuitable and other methods of determining the consistence should be considered.

This European Standard specifies two procedures for sampling fresh concrete, by composite sampling
and by spot sampling.
NOTE  The requirement for remixing the sample before tests on the fresh concrete, or before making test
specimens, is included in the relevant standards.
When mixing and sampling of concrete is done in a laboratory, different procedures may be required.
Additionally, this standard lists common apparatus mentioned in two or more standards of EN 12350
series and EN 12390-2.

This European Standard specifies a method for determining the consistency of fresh concrete by means of the Vebe time.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm.
If the Vebe time is less than 5 s or more than 30 s, the concrete has a consistency for which the Vebe test is unsuitable.

This European standard specifies a method for determining the consistence of fresh concrete by determining the degree of compactability.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm.
If the degree of compactability is less than 1,04 or more than 1,46, the concrete has a consistence for which the degree of compactability test is not suitable.

This European Standard specifies the procedure for determining the slump-flow and t500 time for selfcompacting concrete.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 40 mm.

Typical CO2 uptake values for a range of structures exposed to various environmental conditions are presented. These values can be incorporated into EPDs for the whole life cycle for either: a functional unit, one tonne or one m3 of concrete, without necessarily having any detailed knowledge of the structure to be built.
In the rest of the document, the data will be given per m3.

This CEN Report provides a summary of provisions valid in the place of use used with EN 206:2013. The aims of this CEN Report are to:
a) provide a picture of how EN 206:2013 is being applied in practice;
b) identify areas where EN 206 is being interpreted in different ways;
c) identify areas where CEN Member Countries have found simplification to be necessary;
d) identify where the options listed in EN 206:2013, Annex M to have provisions valid in the place of use have been taken up;
e) identify other clauses in EN 206 where CEN Member Countries have amended or added to the requirements;
f) identify areas within the scope of concrete production and supply not covered by EN 206, but covered by national provisions;
g) identify developing practice that may lead to a need for standardization in the future.
EN 206 uses the phrase ‘provisions valid in the place of use’. This survey uses the term ‘provisions valid in the place of use’ to include regulations, standards and other documents that form the basis of local practice.
As a summary of national requirements, the information in this CEN Report is incomplete and may have been subject to later revisions, particularly if the entry was based on information in CEN/TR15868: 2009. It is insufficient and not intended to provide the basis for design and specification: for this the national requirements (see Table 2) should be studied.
Table 2 identifies CEN Member Countries who did not respond to the questionnaire. The other tables in this CEN Report only include information from CEN Member Countries, or in the view of the authors, the information in CEN/TR 15868:2009 is still likely to be valid.

This European Standard describes the procedures used to determine the carbonation rate of a concrete
expressed in mm/√year.
This European Standard describes the procedure where a standardized storage chamber is used and where
specimens are placed on a natural, but protected from direct rainfall exposure site.

production control.

This European Standard specifies a method for determining the dimensional stability (i. e. the shrinkage and swelling) of cementitious screed, calcium sulfate screed, magnesite screed and synthetic resin screed materials made in accordance with EN 13892-1.

This document reports the data obtained in the Validation Testing Program (VTP) on chloride penetration and
carbonation organized by WG 12 starting from 2009, where the preparation of specimens the collection of results and the statistical analysis were performed by the Institute of Construction Sciences "Eduardo Torroja" of the CSIC of Spain, IETcc –CSIC, under the managing
activities of Prof. Carmen Andrade.

This document provides guidelines for the design and construction of low-rise concrete building
structures of small area to be built in the less developed areas of the world.
This document is applicable to the planning, design and construction of structural reinforced concrete
structures to be used in new low-rise buildings of restricted occupancy, number of stories, and area.
This document can be used as an alternative to the development of a National Concrete Building Code,
or equivalent document in countries where no national design codes are available by themselves, or as
an alternative to the National Concrete Building Code in countries where specifically considered and
accepted by the national standard body or other appropriate regulatory organization.

This European Standard specifies the requirements, the basic performance criteria and the evaluation of conformity for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties steel, polymer or other fibres is also covered. It does not cover prefabricated reinforced components of lightweight aggregate concrete with open structure.
It may also be used to specify products for which there is no standard. Not all of the requirements (Clause 4) of this standard are relevant to all precast concrete products.
If a specific product standard exists, it takes precedence over this standard.
The precast concrete products dealt with in this standard are factory produced for building and civil engineering works. This standard can also be applied to products manufactured in temporary plants on site if the production is protected against adverse weather conditions and controlled following Clause 6 provisions.
The analysis and design of precast concrete products is not within the scope of this standard but it does offer, for non-seismic zones, information about:
-   the choice of partial safety factors defined by the pertinent Eurocode;
-   the definition of some requirements for prestressed concrete products.

This part of EN 1504 gives requirements for
-   substrate condition before and during application of systems and products;
-   storage of systems and products;
-   structural stability during preparation, protection and repair;
-   methods of protection and repair;
-   quality control for execution of work;
-   maintenance of the structure.
These aspects include effects on health and safety, the working environment, the environment and the economy.

This European Standard describes the method for the determination of fly ash fineness by wet sieving on a 0,045 mm sieve (ISO 565).
The standard describes the reference procedure. If other methods are used it needs to be shown that they give results equivalent to those obtained by the reference method. In case of a dispute, only the reference method will be used.

This European Standard describes the procedure for the determination of free calcium oxide content in fly ash.
The standard describes the reference procedure. If other methods are used it needs to be shown that they give results equivalent to those obtained by the reference method.

This European Standard complements the core rules for the product category of construction products as defined in EN 15804+A1 and is intended to be used in conjunction with that standard.
This European Standard applies to concrete and concrete elements for building and civil engineering.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804+A1, this European Standard for concrete and concrete elements:
-   defines the system boundaries;
-   defines the modelling and assessment of material-specific characteristics;
-   defines allocation procedures for multi-output processes along the production chain;
-   defines allocation procedures for reuse and recycling;
-   includes the rules for calculating the LCI and the LCIA underlying the EPD;
-   provides guidance/specific rules for the determination of the reference service life (RSL);
-   gives guidance on the establishment of default scenarios;
-   gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.

This European Standard specifies the composition, characteristics and preparation procedure for reference concrete substrates which are to be used in the test methods to measure performance requirements of products and systems for the repair and protection of concrete structures.
The provisions of this standard are applicable to concrete with a maximum aggregate size of 16 mm or 20 mm or with a maximum aggregate size of 8 mm or 10 mm.

This European Standard is for prefabricated reinforced components of autoclaved aerated concrete to be used in building construction for:
a) Structural elements:
- loadbearing wall components;
- retaining wall components;

- floor components;
- linear components (beams and piers).
b) Non-structural elements:
- nonloadbearing wall components (partition walls);
- cladding components (without fixtures) intended to be used for external facades of buildings;
- small box culverts used to form channels for the enclosure of services;
- components for noise barriers.
Depending on the type and intended use of elements for which the components are utilised, the components can be applied - in addition to their loadbearing and encasing function - for purposes of fire resistance, sound insulation and thermal insulation indicated in the relevant clauses of this European Standard.
Components covered by this standard are only intended to be subjected to predominantly non-dynamic actions, unless special measures are introduced in the relevant clauses of this European Standard.

This European Standard does not cover:
- rules for the application of these components in structures;
- joints (except their strength and integrity E of resistance to fire);
- fixtures;
-  finishes for external components, such as tiling.
NOTE AAC components may be used in noise barriers if they are designed to fulfil also the requirements of EN 14388.

This European Standard does not give rules for the use of HSCF in concrete. Some general rules for the use of type II additions are given in EN 206-1.
NOTE   Supplementary rules related to the use of HCSF in concrete may be given in non conflicting national standards for concrete.

1.1   General
This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made according to the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer.
The report covers commonly used applications (walls/beams/columns and solid slabs and pipes). The range of these applications is further limited to prevent other types of failure than concrete breakout failure (cone failure), bond failure, failure of reinforcement or failure in the steel insert.
Due to lack of information this report does not cover double shell walls, floor plates and small beams for floor systems.
The safety levels are given for information and are intended for short-term-handling and transient situations.
This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2013, 6.3) covering the insert embedment.
This Technical Report does not cover:
—   the design of the lifting inserts independently placed on the market;
—   lifting inserts for permanent and repeated use.
This Technical Report is prepared based on the fact that the anchorage in the concrete of parts of the lifting assembly is governed by the Construction Products Regulation. Lifting accessories independently placed on the market are governed by the Machinery Directive.
1.2   Types of inserts for lifting and handling
This Technical Report applies to the embedment of lifting inserts. Devices made by the precaster may consist of smooth bars, prestressing strands, steel plates with anchorage or steel wire ropes. The system devices may be e.g. internal threaded inserts, flat steel inserts and headed inserts.
Lifting loops of ribbed bars are not covered.
1.3   Minimum dimensions
This Technical Report applies in general to inserts with a minimum nominal diameter of 6 mm or the corresponding cross section. In general, the minimum anchorage depth should be hef = 40 mm.
Wire ropes of diameter less than 6 mm are not covered.

This European Standard is a method for determining the unidirectional non-steady state chloride diffusion and surface concentration of conditioned specimens of hardened concrete. The test method enables the determination of the chloride penetration at a specified age, e.g. for ranking of concrete quality by comparative testing. Since resistance to chloride penetration depends on the aging, including the effects of continual hydration, then the ranking may also change with age.
The test procedure does not apply to concrete with surface treatments such as silanes and it may not apply to concrete containing fibres, see E.1.

This European Standard specifies the requirements of pavers and accessories manufactured from clay for use in the flexible form of construction (see 3.10) and in the rigid form of construction (see 3.11).
This European Standard applies to rectangular and other shaped units intended as construction products in pavements mainly for exterior use, including roofs as roof paving units, but which may also be used internally. The flexible form of construction is subjected to pedestrian and vehicular traffic, while the rigid form of construction is usually subjected to pedestrian traffic.
This European Standard specifies the characteristics and classes of performance and corresponding test methods. It provides for product marking and for the evaluation of conformity of the product to this European Standard.
This European Standard covers only clay pavers and accessories with or without coatings and with or without post firing chemical treatment which do not contain any material with asbestos fibres nor contain formaldehyde.
It excludes products intended for refractory and chemical engineering applications and clay floor tiles. It also excludes clay masonry units.
This European standard does not cover clay pavers having tactile surfaces.

This European Standard specifies the constituent materials, the composition and the mixing procedure to produce a reference masonry mortar with a prescribed consistence for testing mortar admixtures as defined in EN 934-3. It also describes the determination of the water reduction of the test mix compared to the control mix.

This document specifies a method for determining the wear resistance of moulded specimens made from cementitious screed material, primarily for hard aggregate wearing screed materials or optionally for other screed materials.
