Fracture Parameters of Concrete from Drill-Core Specimens from Objects at the Transgas Gas Control Center

Abstract:

This paper presents the results of fracture tests conducted on nine concrete specimens from drill-cores taken from three selected objects located at the former Transgas Gas Control Center in Prague. The specimens were provided with a chevron notch before being tested in three-point bending. The evaluation included arithmetic mean values and basic statistics for the static modulus of elasticity, fracture toughness and specific fracture energy of the assessed concrete specimens.
