ACI SP-156:1995 PDF Download

ACI SP-156:1995 is a specialized publication by ACI International that focuses on the interface fracture and bond in concrete. It aims to provide a fundamental understanding of the behavior of interfaces within concrete composites and their role in the global material behavior. The publication consists of technical papers presented during a special session on fracture mechanics.

The topics covered in this standard include the mechanical properties of the interfacial transition zone, softening slip and size effect in bond fracture, fracture and internal cracking of high-strength concrete under axial compression, experimental studies and modeling of the concrete/rock interface, the role of interfacial fracture toughness in the cracking behavior of high-strength concrete, and the analysis of steel-concrete bond-slip layer fracture using a lattice approach.

Other topics discussed in the publication include fracture mechanics analysis of bond behavior under dynamic loading, prediction and verification of interface debonding for fiber reinforced cementitious material, the effect of lateral stress on debonding and pullout of steel fibers in a cementitious matrix, fluorescence microscopic study of the fracture process of the interfacial zone between a steel fiber and the cementitious matrix, and the influence of silica fume on the strength of the cement aggregate bond.
