Slant shear bond strength
WebFor the slant shear test, a cylindrical mould of size 7.5 × 15 cm is used to conduct the slant shear test as per the provision given in ASTM C882 C882/882 M−13a [27]. The split tensile strength and the bond strength of the GPC mix are evaluated by the following equations. ... The shear bond strength between GPC and PCC substrate is evaluated ... WebThe structural performance of these strengthened structures is highly dependent on the bond performance at the interface between the UHPC and normal-strength concrete (NSC) substrates. This study investigates the shear strength and ultimate failure mode of the interface in UHPC-NSC composites using an experimental program of slant shear test.
