Study on fracture properties of self-compacting concrete using wedge splitting test
This paper reports fracture behavior study on four types of self-compacting concrete with compressive strength ranging from 40 MPa to 150 MPa. Basic fracture properties investigated for each type of self-compacting concrete are: the fracture toughness, the fracture energy, the critical crack length extension and brittle behavior. For achieving this aim, tests were conducted on wedge splitting specimens with initial notch length approximating 100mm. The results show that the fracture energy differs little for self-compacting concrete under consideration in the test, whereas the fracture toughness increases with increasing compressive strength, which is the same as observed in conventional vibrated concrete. At the same time, with computed brittleness index it can be said for sure that as the self-compacting concrete raises its strength, it would fracture in a more brittle manner.
