Characteristics of Bond between Concrete Layers

Four different modes of bond between concrete (polymer modified steel fibre reinforced concrete (PM-SFRC)) layers are discussed in the paper. Wedge splitting test (WST) method was used to determine properties of bond: strength at limit of proportion, maximum strength and parameters for evaluation post-crack behaviour: ductility factor and modulus of toughness. They are compared with those of homogenous PM-SFRC. Maximumu strengths are compared with those determined with Pull-off test method.
