Curing compounds - Test methods - Part 1: Determination of water retention efficiency of common curing compounds

This Technical Specification describes a procedure for determining the ability of a curing compound to prevent the evaporation of water from young concrete when applied immediately after the bleed water has evaporated.
NOTE   The procedure involves application to a horizontal surface; it may not be applicable for use on vertical or sloping surfaces.

Nachbehandlungsmittel - Prüfverfahren - Teil 1: Bestimmung der Wasserrückhaltefähigkeit von üblichen Nachbehandlungsmitteln

Diese Technische Spezifikation beschreibt ein Verfahren zur Bestimmung des Wasserrückhaltevermögens  eines Nachbehandlungsmittels für Beton, mit dem das Verdunsten von Wasser aus jungem Beton verhindert werden soll, wobei das Auftragen des Nachbehandlungsmittels unmittelbar nach Verdunsten von abgesondertem Wasser erfolgt.
ANMERKUNG   Das Verfahren betrifft die Anwendung auf horizontale Oberfläche; es ist überlicherweise nicht an senkrechten oder geneigten Oberflächen anwendbar.

Produits de cure - Méthodes d'essai - Partie 1 : Détermination de l'efficacité de protection des produits de cure courants

La présente Spécification technique décrit un mode opératoire permettant de déterminer la capacité d’un produit de cure, appliqué immédiatement après que l’eau de ressuage s’est évaporée, à empêcher l’évaporation de l’eau d’un béton au jeune âge.
NOTE   Le mode opératoire implique l’application sur une surface horizontale ; il peut ne pas s’appliquer à une utilisation sur des surfaces verticales ou inclinées.

This Technical Specification (CEN/TS) was approved by CEN on 3 July 2006 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
