The fragmentation of standard concrete cylinders during the compressive testing

The paper alternatively discusses the concrete cylinder compressive test. B asically, the fracture is treated as a single comminution process. After co mpressive testing, the main concrete debris as well as the samples of fine- grained particles, including grain-size distribution and grain shape, are a nalyzed. The fine-grained samples are distributed according to a R(osin)-R( ammler)-S(perling)-distribution. The distribution parameters depend on the mechanical properties of the concrete. The shape factor increases as the co mpressive strength increases. Generally, with an increase in the strength p roperties, the fracture becomes non-regular due to a 'homogenization' of th e fracture process.
