ABSTRACT / САЖЕТАК:

Worldwide, the concrete structures under harsh environment cannot reach the expected service life. In order to restore the damaged, different types of repair mortars can be used. The aim of this paper is to evaluate the physicomechanical properties of repair cement-based mortars that contain 0, 10, 20 and 30% slag as SCM, prepared with a water-to-binder ratio of 0.5, by using the concept of performance index. Applied slag represents a by-product from the one company located in Serbia. The compressive strength, modulus of elasticity, and capillary water absorption of examined mortars were determined at the age of 28 days.
