Aggregates - Test methods on reactivity to alkalies

Le présent document décrit les méthodes d'essai permettant de qualifier la réactivité d'un granulat aux alcalins. Ces méthodes, associées à une analyse chimique élémentaire et/ou une étude pétrographique (FD P 18-543) , autorisent un classement en : Non Réactif (NR) , Potentiellement Réactif (PR) , Potentiellement Réactif à effet de Pessimum (PRP) selon des critères spécifiés dans le fascicule de documentation FD P 18-542.

Aggregates -Test methods on reactivity to alkalies

Dans la série des normes P 18-... qui concerne les granulats, le présent document définit une méthodologie d'évaluation de la stabilité des granulats en milieu alcalin. Il autorise ainsi leur qualification vis-à-vis de l'alcali-réaction. Ce document est très largement inspiré des normes françaises qu'il remplace.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

mandatory clauses to satisfy,
non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!

What is the Redline format?

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.

The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
