(1) This document applies to concrete for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures. (2) The concrete under this document can be: - normal-weight, heavy-weight and lightweight; - 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 document specifies requirements for: - the constituents of concrete; - the properties of fresh and hardened concrete; - the limitations for concrete composition; - the specification of concrete; - the delivery of fresh concrete, - the production control procedures; - the assessment criteria for individual values. (4) This document does not apply to: - aerated concrete; - foamed concrete; - concrete with density less than 800 kg/m3; - refractory concrete. (5) This document does not cover health and safety requirements for the protection of workers during production and delivery of concrete.

(1) This document specifies the scheme for the conformity assessment and assessment criteria for concrete. (2) The document provides technical rules for testing of samples and assessment of the performance of the concrete. It also provides rules for actions to be followed in the event of non-conformity of the product or negative assessment. (3) In this document, the word “concrete” is used to refer concrete as defined in prEN 206 1. Such a concrete is produced at a given plant and belongs to a particular type and a particular strength class, as defined and specified in prEN 206 1.

(1) This document specifies additional requirements to prEN 206 1 for the constituents, specification and conformity control of concrete used in: - bored piles constructed in accordance with EN 1536; - diaphragm walls constructed in accordance with EN 1538; - cast-in-place displacement piles constructed in accordance with EN 12699; - micropiles constructed in accordance with EN 14199. (2) The requirements provided in this document are specified in accordance with prEN 206 1:2024, 7.2 Specifications for designed concrete. (3) This document can also apply to applications in special geotechnical works other than those listed above. NOTE 1 For special geotechnical works provisions on cement, minimum cement content, minimum fines content, maximum water/binder ratio, target values of fresh concrete properties and maximum tolerances for target values can deviate from the provisions for other works in prEN 206 1. (4) This document is based on the assumption that the specification is based on considerations including the site conditions and the conditions for execution of concrete used in special geotechnical works. NOTE 2 Guidance for the specification of concrete used in special geotechnical works can be found in the informative Annex A.

This document specifies the methods for the chemical analysis of cement. This document describes the reference methods and, in certain cases, an alternative method which can be considered to be equivalent. In the case of a dispute, only the reference methods are used. An alternative performance-based method using X-ray fluorescence (XRF) is described for SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl and Br. This method is based on beads of fused sample and analytical validation using certified reference materials, together with performance criteria. A method based on pressed pellets of un-fused sample can be considered as equivalent, providing that the analytical performance satisfies the same criteria. An alternative performance-based method using inductively coupled plasma optical emission spectroscopy (ICP-OES) is described for SO3. When correctly calibrated according to the specified procedures and reference materials, XRF and ICP-OES provides methods equivalent to the reference methods but has not been validated for use yet as a reference procedure for conformity and dispute purposes. They can be applied to other relevant elements when adequate calibrations have been established. Any other methods can be used provided they are calibrated, either against the reference methods or against internationally accepted reference materials, in order to demonstrate their equivalence. This document describes methods which apply principally to cements, but which can also be applied to their constituent materials. They can also be applied to other materials, the standards for which call up these methods. Standard specifications state which methods are to be used.

This document specifies a test method for determination of the activity concentrations of the radionuclides potassium (K-40), uranium (U-238) and thorium (Th-232) in mineral-based construction products.  

This document also specifies a method for the calculation of activity index (AI) according to Directive 2013/59/EURATOM, Annex 8 [12] for mineral-based construction products.  

The method is intended to be used for factory production control.
