Cement - Composition, specifications and conformity criteria for very low heat special cements

This European Standard defines and gives the specifications of six distinct very low heat special cement products and their constituents. The definition of each cement includes the proportions in which the constituents are to be combined to produce these distinct products in a single strength class having a limited heat of hydration value. The definition also includes requirements the constituents have to meet and the mechanical, physical, chemical and heat of hydration requirements for these products. This European Standard also states the conformity criteria and the related rules. Necessary durability requirements are also given.
In addition to the specified requirements, an exchange of additional information between the cement producer and user can be helpful. The procedures for such an exchange are not within the scope of this European Standard but should be dealt with in accordance with national standards or regulations or can be agreed between the parties concerned.
NOTE 1   The word "cement" in this European Standard is used to refer to very low heat special cement unless otherwise indicated.
NOTE 2   The risk of early-age thermal cracking in concrete depends upon the properties and execution and is, therefore, also dependent on factors other than the heat of hydration of the cement.

Zement - Zusammensetzung, Anforderungen und Konformitätskriterien von Sonderzement mit sehr niedriger Hydratationswärme

Diese Europäische Norm legt die Anforderungen an sechs verschiedene Sonderzementprodukte mit sehr niedriger Hydratationswärme und ihre Bestandteile sowie die entsprechenden Definitionen fest. Die Definition jedes Zements beinhaltet die Anteile der Bestandteile, die erforderlich sind, um jedes dieser Produkte für eine einzelne Festigkeitsklasse mit einem Grenzwert für die Hydratationswärme herzustellen. Sie beinhaltet ferner die Anforderungen an die Bestandteile und an die mechanischen, physikalischen und chemischen Eigenschaften sowie die Anforderungen an die Hydratationswärme für diese Produkte. Darüber hinaus werden in dieser Europäischen Norm die Konformitätskriterien und die entsprechenden Regeln festgelegt. Die notwendigen Anforderungen an die Dauerhaftigkeit sind auch angegeben.
Neben den festgelegten Anforderungen kann ein Austausch von zusätzlichen Informationen zwischen Zementhersteller und -anwender hilfreich sein. Die Vorgehensweisen für einen solchen Informationsaustausch sind nicht Gegenstand dieser Europäischen Norm. Sie sollten in Übereinstimmung mit nationalen Normen oder Vorschriften festgelegt werden oder können zwischen den Beteiligten vereinbart werden.
ANMERKUNG 1   Sofern nicht anders angegeben, kennzeichnet das Wort „Zement" in dieser Europäischen Norm ausschließlich Sonderzemente mit sehr niedriger Hydratationswärme.
ANMERKUNG 2   Die Gefahr der frühzeitigen wärmebedingten Rissbildung im Beton hängt von den Eigenschaften des Betons und von der Ausführung ab und ist daher nicht nur von der Hydratationswärme des Zements, sondern auch von anderen Faktoren abhängig.

Ciments - Composition, spécifications et critères de conformité de ciments spéciaux à très faible chaleur d'hydratation

Cement - Sestava, zahteve in merila skladnosti za posebne cemente z zelo nizko toploto hidratacije

Ta evropski standard določa in vsebuje zahteve za šest različnih posebnih cementnih izdelkov z zelo nizko toploto hidratacije in njihove sestavine. Definicija vsakega cementa vključuje razmerja, v katerih se sestavine združijo, da se proizvedejo ti različni izdelki enega trdnostnega razreda z omejeno vrednostjo toplote hidratacije. Definicija vključuje tudi zahteve, ki jih morajo izpolnjevati sestavine, ter mehanske, fizikalne in kemijske zahteve ter zahteve glede toplote hidratacije za te izdelke. Ta evropski standard določa tudi merila skladnosti in povezana pravila. Navedene so tudi zahteve za potrebno trajnost.
Poleg navedenih zahtev je lahko koristna tudi izmenjava dodatnih informacij med izdelovalcem cementa in uporabnikom. Postopki za takšno izmenjavo ne spadajo v področje uporabe tega evropskega standarda, temveč naj bi se obravnavali v skladu z nacionalnimi standardi ali predpisi ali po dogovoru med vpletenimi stranmi.
OPOMBA 1: Izraz »cement« v tem evropskem standardu se nanaša na poseben cement z zelo nizko toploto hidratacije, če ni navedeno drugače.
OPOMBA 2: Tveganje za termične razpoke v mladem betonu je odvisno od lastnosti in izvedbe ter je torej odvisno tudi od drugih dejavnikov, ne samo od toplote hidratacije cementa.

— use of the terminology given by the Construction Products Regulation (Regulation (EU) No 305/2011); — a clause “Dangerous substances” has been added; — the former Annex A (informative) “Water-soluble hexavalent chromium” has been deleted; — Annex ZA has been revised in accordance with the Construction Products Regulation (Regulation (EU) No 305/2011). This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this document. The various stages in the development of a European Standard for common cement, in response to the preliminary mandate given to CEN by the EC and the EFTA, are described in EN 197-1. It is indicated that, in view of the large numbers of different cements involved, it was considered necessary to separate the "common cements", which are now covered by EN 197-1, from special cements, i.e. those with special properties or those having hardening processes not mainly dependent on the hydration of calcium silicates. The low heat property for common cements is covered by EN 197-1. A need for control of heat development during hydration of concrete is referred to in EN 206. Classification of cements with respect to heat of hydration is one method whereby heat development of concrete can be controlled. The purpose of this European Standard is therefore to specify the heat of hydration for very low heat special cements. Composition and other requirements are those specified in EN 197-1 for common cements. Conformity criteria are additionally specified. The requirements in this European Standard are based on the results of tests on cement in accordance with EN 196-1, EN 196-2, EN 196-3, EN 196-5, EN 196-7, EN 196-8 and EN 196-9. The scheme for the evaluation of conformity in EN 197-2 is applicable to very low heat special cements. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
