Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as wellhe most common method is to use cylinder cores drilled off the structureomber 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.
