    Feb 23, 2020 According to Ref. 35, the strength ratio between a sample with a slenderness of 1.0 and 2.0 is approximately 1.1 to 1.2. This means that the cubecompressive strength f c,m,cube is greater by a factor of 1.1 to 1.2 than the compressive strength determined on a cylinder f c,m,cylinder.

    Compressive Strength An Overview Sciencedirect Topics

    Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber 1998b was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.
