Abstract: The potentially aggressive environments in some parts of Saudi Arabia have resulted in premature deterioration of many concrete structures during their service performance life. To achieve more effective and long lasting repair materials, it is essential that the properties of the repair materials and the substrate are compatible. This study aims at evaluating the mechanical properties of selected classes of repair materials that are commonly used in repair application within the Kingdom. A total of 114 specimens were cast to investigate some of the important properties of nine widely used local repair materials available in the market. The properties evaluated in this study are: drying shrinkage, compressive strength and modulus of elasticity. Out of each of the selected repair materials, six specimens for shrinkage and six specimens for compressive strength and modulus of elasticity measurements were considered in the study. Additional specimens made from cement paste were used as control samples for the study. Results of the present study show that all repair materials must be checked experimentally to confirm the properties given by the supplier before their use in any field application. The study also recommends that the selection of suitable repair material should be based on the type of application, as application changes properties requirement changes. For example, for one application compressive strength requirement may be more critical, while in another application shrinkage may be of great concern. Keywords: Repairing materials, Cementitious, Drying shrinkage, Compressive strength, Modulus of elasticity.
