Abstract:
Concrete is usually specified in terms of the strength of standard specimens (normally cylinders or cubes) which are cast from samples of the fresh concrete. If the concrete in a structure is to be investigated using core tests, an understanding of the factors which influence the measured strength of a core together with a knowledge of the relationship between the strength of standard specimens and the strength of concrete in structures are required. The paper presents results of both laboratory research and site investigations in which some of the relevant factors have been investigated.
