Electrochemical realkalization and chloride extraction treatments for reinforced concrete - Part 1: Realkalization

This document specifies a procedure for carrying out impressed current electrochemical realkalization of carbonated reinforced concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement embedded in concrete.
This document does not apply to concrete containing prestressing steel which can suffer hydrogen embrittlement during realkalization, or to concrete containing epoxy-coated or galvanized reinforcement, or if chloride contamination is contributing to reinforcement corrosion.

Elektrochemische Realkalisierung und Chloridextraktionsbehandlungen für Stahlbeton - Teil 1: Realkalisierung

Diese Technische Spezifikation legt ein Verfahren zur elektrochemischen Realkalisierung von karbonati-siertem Stahlbeton in bestehenden Bauwerken mittels Fremdstrom fest. Es ist anwendbar auf Teile von Gebäuden mit normaler, in Beton eingebetteter Bewehrung, die der Atmosphäre ausgesetzt sind.
Diese Technische Spezifikation ist nicht anwendbar auf Beton mit vorgespannter Bewehrung, die Wasser-stoffversprödung infolge der Realkalisierung unterliegen kann, auf Beton mit organisch beschichteter oder verzinkter Bewehrung sowie wenn Chlorid zur Korrosion der Bewehrung führt.

Ré-alcalinisation électrochimique et traitements d'extraction des chlorures applicables au béton armé - Partie 1 : Ré-alcalinisation

La présente Spécification technique prescrit un mode opératoire pour procéder à la ré-alcalinisation électrochimique par courant imposé du béton armé carbonaté dans des structures existantes. Elle est applicable à des éléments de structure exposés au milieu ambiant et armés avec des fers noyés dans le béton.
La présente Spécification technique ne s'applique pas au béton contenant des aciers de précontrainte qui peuvent subir une fragilisation due à l'hydrogène lors de la ré-alcalinisation ou au béton contenant des armatures revêtues époxyde ou galvanisées, ou lorsque la contamination par les chlorures contribue à la corrosion des armatures.

SIST EN 14038-1:2016

This European Standard specifies a procedure for carrying out impressed current electrochemical realkalization (ER) of carbonated reinforced concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement embedded in concrete.
This European Standard does not apply to concrete containing prestressing steel which can suffer hydrogen embrittlement during realkalization, or to concrete containing epoxy-coated or galvanized reinforcement, or if chloride contamination is contributing to reinforcement corrosion.
NOTE   In case of post-tensioned prestressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.

Assessment of in-situ compressive strength in structures and precast concrete components
SIST EN 13791:2019

(1) This document:
- 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;
NOTE    To align with the design standard EN 1992-1-1, where the compressive strength is based on 2:1 cylinders, the in situ compressive strength is based in 2:1 cores of diameter ≥ 75 mm.
- 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 for assessing the conformity with the compressive strength class of concrete supplied to structures under construction where standard tests indicate doubt or where the quality of execution is in doubt.
(2) This document provides requirements for determining the in situ strength at test locations and the characteristic strength of test regions, but how this information is to be applied needs to be considered in the light of the specific situation and engineering judgement applied to the specific case.
(3) This document does not include the assessment of the quality of concrete for properties other than compressive strength, e.g. durability-related properties.
(4) This document 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+A1:2016, 5.5.1.2 or 8.4.
(5) This document does not cover the procedures or criteria for the routine conformity control of precast concrete components using either direct or indirect measurements of the in situ strength.

CEN/TR 17080:2018(Main)
Design of fastenings for use in concrete - Anchor channels - Supplementary rules
SIST-TP CEN/TR 17080:2018

EN 1992-4:2018 covers anchor channels located in cracked or uncracked concrete subjected to tensile loads and/or shear loads transverse to the longitudinal channel axis as well as combinations of these loads. Shear loads acting in direction of the longitudinal axis of the channel and combinations of shear loads acting transverse and in direction of the longitudinal axis of the channel, combinations of tensile loads and shear loads acting in direction of the longitudinal axis of the channel and combinations of loads in all three directions are excluded.
This Technical Report provides design rules for anchor channels under static and quasi-static shear loads acting in direction of the longitudinal channel axis and all possible combinations of shear and tension loads acting on the channel as well as design rules for anchor channels with supplementary reinforcement to take up shear loads, additional and alternative to the provisions of EN 1992- 4:2018. All relevant failure modes are considered and will be verified. Fatigue, impact and seismic loads are not covered.
The design rules in this document are only valid for anchor channels with a European Technical Product Specification. The design provisions for shear loads acting in direction of the longitudinal axis of the channel cover the following anchor channels and applications:
-   Anchor channels with 2 or 3 anchors.
-   Anchor channels where the shear load in the longitudinal axis of the channel is transferred to the channel by corresponding locking channel bolts creating mechanical interlock by means of a notch in the channel lips or serrated channel bolts which interlock with serrated lips of the channel (Figure 1).
-   Anchor channels produced from steel with at least two metal anchors rigidly connected to the back of the channel (e.g. by welding, forging or screwing). The anchor channels are placed flush with the concrete surface. A fixture is connected to the anchor channel by channel bolts with nut and washer.
-   Anchor channels close to the edge placed either parallel or transverse to the edge of the concrete member. The design provisions for concrete edge failure do not cover channel orientations inclined to the concrete edge.
The design method for anchor channels loaded in shear in direction of the longitudinal axis of the channel follows closely the existing design model for headed fasteners. For reasons of simplicity modifications specific for anchor channels are used where necessary.
The design provisions for the supplementary reinforcement to take up shear loads in case of anchor channels situated parallel to the edge and loaded in shear transverse to the longitudinal axis apply to anchor channels with unlimited number of anchors.
Examples of anchor channels and channel bolts ensuring mechanical interlock are given in Figure 1.
