Abstract

Epoxy grouts have been widely used for repairing and rehabilitating structure and transportation pipelines because they are resistant to typical aggressive solutions. In recent years, grouts are used as structural infill in defective structures. The appropriateness of using grouts is highly dependent on the required strength of structures in service condition. This paper experimentally studies the mechanical properties of four epoxy grouts as infill components for structural repair. Compressive, tensile, shear, and flexural properties are determined and compared. The compressive and tensile strengths of the grouts are found to be within the range of 60-115 MPa and 10-30 MPa respectively, while their compressive modulus ranging from 1.5 to 6.0 GPa were measured. The overall results suggest the suitability of these grouts for desired structural repair applications. Finally, recommendations are made on the relevance of using these grouts based on their mechanical properties. The outcome obtained from the study is expected to enhance the applicability of epoxy grouts as infill in structural repair and rehabilitation.
