The Analysis of the Behavior of Alkali-Activated Materials Applied as a Repair Mortar

Article Preview

Abstract:

The paper deals the possibility of alkali activated materials utilization as matrix for repair mortars, determined for rehabilitation of reinforced concrete structures. Alkali activated materials have owing to their specific properties a high potential especially for utilization in materials determined for specific applications. Materials showing in comparison with the cement matrix significantly higher resistance against the effect of chemical substances are the so-called alkali activated materials. One of the essential conditions for the successful use of repair mortars is their sufficient cohesion to the surface respectively with the surface of rehabilitated structures.
