BLL Posted April 13, 2015 Report Share Posted April 13, 2015 (edited) bonsoirje travaille sur un projet ou le marché exige des éprouvettes en cube de 20*20*20 cm pour avoir la résistance par écrasement .le laboratoire utilise des éprouvettes en cube aussi mais de 15*15*15 cm !comme il est connu , pour passer d'une résistance d'un cube (15*15*15) à une résistance d'un cylindre, on multiplie la résistance par un coefficient de corrélation qu'on le prend en général 0.83 ....ma question est si ce coefficient est constant ???? je veux dire si on utilise des cubes mais de 20*20*20 cm, quelle est la valeur de ce coefficient pour avoir une résistance d'un cylindre ?merci Edited April 22, 2015 by BLL 2 Quote Link to comment Share on other sites More sharing options...
