With the aim of generating solutions against the deterioration of the steel embedded in the concrete are studied three cementitious systems obtained from: Portland cement, steel blast furnace slag and fly ash from coal-fired power plants. The main objective was to compare the mechanical performance and durability of each of the systems independently. The cement with steel slag and fly ash alkali activated by combining alkali activators: sodium silicate and sodium hydroxide. The characterization of the powdered raw materials and products formed reaction was performed by analysis of X-ray diffraction. The evaluation of mechanical properties was performed in compression then the concrete will be exposed to the entry of aggressive agents such as chloride ions during 24 months, time when their electrochemical properties were evaluated. The results for various mixtures indicate that these alternative materials (fly ash and steel slag) generate adequate mechanical and durability performance.
