Abstract

This paper describes a number of statistical methods to estimate, through an analysis of in-place test results, the in-place compressive strength of concrete expressed as strength of standard specimens. The evaluation of the probable existence of a linear correlation as a function of sample size is discussed. The regression laws and the degree of reliability of the estimates obtained is also discussed. A criterion is proposed for the choice of the number of points to be used in the regression. Finally a method is proposed, knowing the numberm of replicated in-place tests, to estimate the equivalent numbern of replicated tests performed on standard specimens.

Résumé

Cet article présente diverses méthodes statistiques qui permettent, par le biais de l'analyse des résultats d'essais śinsitu’, l'estimation de la résistance du béton exprimée comme résistance sur échantillons standard. Il est procédé à l'évaluation de l'existence probable d'une corrélation linéaire en fonction de la taille de l'échantillon. Il est procédé à l'analyse des lois de régression, ainsi que du niveau de fiabilité des estimations obtenues. Il est proposé un critère pour l'évaluation du nombre de points à employer dans la régression. Enfin, il est proposé une méthode qui permet, pour un nombrem d'essais répétés selon les méthodes non-destructives, d'estimer le nombren équivalent d'essais répétés sur échantillons standard.
