Products and systems for the protection and repair of concrete structures - Test methods - Determination of resistance of capillary absorption

This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It specifies a method for determining the resistance to water absorption of repair products and systems, as defined in EN 1504-3 .
The method is based on measuring the increase in weight due to capillary absorption of water over a fixed time interval. The weight of water absorbed is expressed as a coefficient, indicating the tendency of the specimen to imbibe water by capillary action without external pressure applied.

Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Bestimmung der kapillaren Wasseraufnahme

Diese Europäische Norm enthält Festlegungen für ein Verfahren zur Bestimmung der kapillaren Wasseraufnahme von Produkten und Systemen für den Schutz und die Instandsetzung von Beton.

Produits et systemes pour la protection et la réparation des structures en béton - Méthodes d'essai - Détermination de l'absorption capillaire

La présente norme européenne fait partie d'une série de normes traitant des produits et des systemes de protection et de réparation des structures en béton. Elle spécifie une méthode pour déterminer l'absorption d'eau des produits et des systemes de réparation, tels que décrits dans l'EN 1504-3 ) .
La méthode s'appuie sur le mesurage de l'augmentation de poids due a l'absorption capillaire d'eau pendant un intervalle de temps déterminé. Le poids de l'eau absorbée est exprimé en tant que coefficient indiquant la tendance de l'éprouvette a s'imprégner d'eau par action capillaire sans aucune pression extérieure.

EN 13057:2002 (E)3ForewordThis document EN 16057:2002 has been prepared by Technical Committee CEN/TC 104 "Concrete and relatedproducts", 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of an identical text orby endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latestby December 2002.It has been prepared by sub-committee 8 "Products and systems for the protection and repair of concretestructures", the secretariat of which is held by AFNOR.This European Standard is one of a series dealing with products and systems for the protection and repair ofconcrete structures. It gives definitions, requirements, quality control and attestation of conformity for the structuraland non-structural repair of concrete structures.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.SIST EN 13057:2002



EN 13057:2002 (E)41 ScopeThis European Standard is one of a series dealing with products and systems for the protection and repair ofconcrete structures. It specifies a method for determining the resistance to water absorption of repair products andsystems, as defined in prEN 1504-31.The method is based on measuring the increase in weight due to capillary absorption of water over a fixed timeinterval. The weight of water absorbed is expressed as a coefficient, indicating the tendency of the specimen toimbibe water by capillary action without external pressure applied.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 196-1, Methods of testing cement - Part 1: Determination of strength.ISO 556, Conditioning and testing - Standard atmospheres - Definitions.3 PrincipleThe method of test is applicable to repair grout, mortar or concrete specimens. Hereafter the term mortar specimenrefers equally to concrete, unless stated to the contrary.Resistance to capillary absorption is measured on the trowelled upper face of 100 mm diameter cylindricalspecimens of mortar, with a thickness of at least 20 mm or three times the maximum aggregate size, whichever isthe greater. As an alternative, the cut face of 100 mm diameter cores of repair mortar may be used.4 Equipment4.1Standard laboratory climate in accordance with the requirements of annex A.4.2Moulds for producing specimens made from non absorbent, rigid material, not attacked by cement paste orpolymers, of (100 ± 5) mm internal diameter and (25 ± 0,5) mm depth, or other depth necessary to satisfy therequirement of being three times the maximum aggregate size.Suitable moulds may be prepared from rigid polypropylene pipe, cut to the appropriate length. It shall be ensuredthat around the circumference, the length of pipe is within ± 0,5 mm of the target depth of the specimen.4.3Flat bottomed, rigid tray and cover, into which the specimens are placed, resting on knife-edge supportsto achieve a depth of water immersion of (2,0 ± 1,0) mm. The area of the tray should be at least twice the area ofthe test specimen(s) to be stood in the tray with a cover to enclose fully the tray.4.4Demineralised water.4.5Balance with a minimum resolution of 0,01 g.4.6Stopwatch accurate to 1 second.

An alternative is to use a forced action pan mixer (
