Abstract

We analyze the mechanical behavior of cracked concrete repaired by epoxy deposition in response to splitting tests uniaxial compression tests and three-point bending tests. Digital Image Correlation and Finite Element Method - based models are used to predict the behavior of repaired concrete for a variety of loading configurations. Parametric studies indicate that repaired concrete is stronger and more ductile than non-repaired concrete. It is recommended to deposit epoxy in cracks above 0.01 mm in width.
