(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.
(1) This European Standard 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 European Standard can be: - 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 deviati
