Umfang (scope):

(1) This document specifies additional requirements to FprEN 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.NOTE 1 The requirements provided in this document are specified in accordance with FprEN 206 1:2025, 7.2 Specifications for designed concrete.(2) This document can also apply to applications in special geotechnical works other than those listed above.NOTE 2 For other special geotechnical works than those listed in paragraph (1) (e.g. cut-off walls or temporary works) provisions valid in the place of use can have provisions on cement types and suitability, minimum total binder content, minimum fines content, maximum water/total binder ratio, target values of fresh concrete properties and maximum tolerances for target values deviating from the provisions in FprEN 206 1.(3) 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 3 Guidance for the specification of concrete used in special geotechnical works can be found in Annex A.(4) Annex C specifies requirements applying to plastic concrete which is generally used for non-structural structures and groundwater barrier walls (cut-off walls).
