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
