Evaluation of Behavior of the Joint Between Two Concrete Layers During Splitting

Evaluation of the Resistance to Crack Propagation of High-Performance Concretes by the Wedge Splitting Test Method

“…In practice, the equivalent splitting tensile strength up to a crack width of 0.2 mm (f0,2) is most used to calculate the resistance of concrete to crack propagation, and equation ( 1) takes the following form [21]:…”

Bond strength evaluation of polymer modified cement mortar incorporated with polypropylene fibers

“…There are several tests available to evaluate the behavior and/or the strength of overlay-to-substrate interfaces. These tests can be classi ed into three categories according to the stress resultant at the interface 1) axial, includes; Pull-off (Long and Murray, 1984;Delatte et al, 2000), Direct Tension (Ohama et al, 1986), and Split-Tensile test (Sustersic and Zajc, 1999;Tschegg et al, 2000), 2) bending, includes exural test (Wall et al, 1986;Abu-Tair et al, 1996;Kunieda et al, 2000;Kamada and Li, 2000), and 3) shear, includes testing by; Direct Shear (Chen et al, 1995;Li et al, 1997), Slant-Shear (Tayeh et al, 2013;Pattnaik, 2015), Bi-surface shear, and Push-off (Hofbeck et al, 1969;Mattock, 1974;Crane, 2010).…”
