Products and systems for the protection and repair of concrete structures - Test methods - Determination of carbonation depth in hardened concrete by the phenolphthalein method
The phenolphthalein test method is intended to measure the depth of the carbonated layer near the surface of hardened concrete. It is not suitable for concrete made with calcium aluminate cement. It may be used on site or in the laboratory, on test specimens or on cores or fragments removed from hardened concrete structures.
Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Bestimmung der Karbonatisierungstiefe im Festbeton mit der Phenolphthalein-Prüfung
Die Phenolphthalein Prüfung ist für die Bestimmung der Karbonatisierungstiefe nahe der Oberfläche des Festbetons vorgesehen. Sie ist nicht geeignet für Beton, der aus Tonerdezement hergestellt wurde. Sie kann am Einsatzort oder im Labor an Probekörpern oder an aus dem Festbeton entnommenen Bohrkernproben oder Bruchstücken angewendet werden.
Produits et systemes pour la protection et la réparation des structures en béton - Méthodes d'essai - Mesurage de la profondeur de carbonatation d'un béton armé par la méthode phénolphtaléine
La méthode d’essai a la phénolphtaléine sert a mesurer la profondeur de la couche carbonatée située pres de la surface du béton durci. Cette méthode ne convient pas lorsque le béton est formé a base de ciment alumineux. Elle peut etre utilisée sur site ou en laboratoire, sur des éprouvettes, des carottes ou des fragments prélevés sur des structures en béton durci.

EN 14630:2006 (E) 3 Foreword This document (EN 14630:2006) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest April 2007, and conflicting national standards shall be withdrawn at the latest by December 2008. It has been prepared by sub-committee 8 "Protection and repair of concrete structures" (Secretariat AFNOR). This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It describes a method for determining the depth of carbonation of concrete. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 14630:2006 (E) 4 Introduction Steel reinforcement in concrete may be at risk of corrosion if the cover is carbonated. ENV 1504-9 defines the principles for protection and repair of concrete structures which have suffered or may suffer damage or deterioration and gives guidance on the selection of products and systems which are appropriate for this intended use. To establish whether there is a sufficient depth of uncarbonated concrete to protect the reinforcement for the remainder of the design life of the structure, the total depth of cover and the depth of carbonation should be determined. The total depth of cover can be determined by physical measurement or by the use of a cover meter. The depth of carbonation determined as defined in this standard is the most widely used method of measuring carbonation depth. It is measured by using the indicator phenolphthalein. Above a pH value of approximately 9 the indicator gives the concrete a red-purple colour. Only concrete which is coloured is sufficiently alkaline to provide passivity for steel.
