Testing hardened concrete - Part 13 : determination of secant modulus of elasticity in compression

Le présent document spécifie la méthode de détermination du module sécant d'élasticité en compression du béton durci, en utilisant des éprouvettes pouvant avoir été moulées ou prélevées dans une structure. La méthode d'essai permet de déterminer les deux modules sécants d'élasticité : le module initial, Ec,0 mesuré lors de la première application de la charge et le module stabilisé, Ec,s mesuré après trois cycles de chargement. Deux méthodes différentes sont indiquées. La première (méthode A) porte sur la détermination à la fois du module initial et du module stabilisé, la seconde (méthode B) concerne la détermination du module stabilisé uniquement.

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.
