heal.abstract	The aim of this experimental work was to investigate the performance of a special concrete repair material. The use of silica fume (SF)-Ca(OH)(2) mixture, with and without cement addition in reinforced mortars has been studied. The examination of the hydration reaction progress by X-Ray Diffraction (XRD), Differential Thermal Analysis-Thermogravimetry (DTA-TG), and Scanning Electron Microscopy (SEM) analysis of SF-Ca(OH)(2) mixture with various cement ratios, shows that calcium silicate hydrate is formed in a desired extent. Damaged specimens repaired by the above-mentioned materials also showed low carbonation depth and the lowest corrosion rate, close to of undamaged specimens. This is attributed to the formation of C-S-H compounds at the interface between these mixtures and cement mortar, resulting in the creation of good binding properties of the repair materials.
