Modified Disk-Shaped Compact Tension Test for Measuring Concrete Fracture Properties

A new approach for measuring the specific fracture energy of concrete denoted modified disk-shaped compact tension (MDCT) test is presented. The procedure is based on previous ideas regarding the use of compact tension specimens for studying the fracture behavior of concrete but implies significantm...
