Testing fresh concrete - Part 4: Degree of compactability
This standard specifies a method for determining the consistency of fresh concrete by determining the degree of compactability. It is not applicable to concrete of which the maximum size of aggregate exceeds 63 mm. If the degree of compactability is less than 1,04 or more than 1,46, the concrete has a consistency for which the degree of compactability test is insensitive.
Prüfung von Frischbeton - Teil 4: Verdichtungsmaß
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Konsistenz von Frischbeton durch Berechnung des Verdichtungsmaßes fest.
Diese Norm gilt nicht, wenn das Größtkorn der Gesteinskörnung mehr als 63 mm beträgt.
Wenn das Verdichtungsmaß kleiner als 1,04 oder größer als 1,46 ist, hat der Beton eine Konsistenz, für die die Prüfung des Verdichtungsmaßes nicht geeignet ist.
Essai pour béton frais - Partie 4 : Degré de compactabilitié
La présente Norme européenne prescrit une méthode de détermination de la consistance du béton frais par l’évaluation de son indice de serrage.
Elle n’est pas applicable aux bétons contenant des granulats dont la dimension maximale du plus gros granulat est supérieure à 63 mm.
Si l’indice de serrage est inférieur à 1,04 ou supérieur à 1,46, le béton a une consistance pour laquelle l’essai de l’indice de serrage n'est pas adapté.

EN 12350-4:2009 (E) 3 Foreword This document (EN 12350-4:2009) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, 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of an identical text or by endorsement, at the latest by September 2009, and conflicting national standards shall be withdrawn at the latest by September 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12350-4:1999. This standard is one of a series concerned with testing concrete. This series EN 12350 includes the following parts.
Part 1: Sampling; Part 2: Slump-test;
Part 3: Vebe test;
Part 4: Degree of compactability; Part 5: Flow table test;
Part 6: Density;
Part 7: Air content - Pressure methods; Part 8: Self-compacting concrete - Slump-flow test (in preparation); Part 9: Self-compacting concrete - V-funnel test (in preparation); Part 10: Self-compacting concrete - L-box test (in preparation); Part 11: Self-compacting concrete - Sieve segregation test (in preparation); Part 12: Self-compacting concrete - J-ring test (in preparation).
CAUTION — When cement is mixed with water, alkali is released. Take precautions to avoid dry cement entering the eyes, mouth and nose whilst mixing concrete. Prevent skin contact with wet cement or concrete by wearing suitable protective clothing. If cement or concrete enters the eye, immediately wash it out thoroughly with clean water and seek medical treatment without delay. Wash wet concrete off the skin immediately. SIST EN 12350-4:2009
