  The development of alternative and greener cementitious materials based on industrial wastes is one way to reduce the environmental impact of the building sector.The main objective of this work is to perform a detailed analysis of the strength and structure of alkali-activated ground granulated blastfumace slag at different times of hydration.In particular, we have investigated the structure development of the material by use of the complementary techniques, X-ray diffraction (XRD) and Infrared spectroscopy (IR).For the alkali-activation,water glass with various moduli was used.For all sample compositions, both the silica and water contents were kept at fixed values whereas the sodium content was systematically varied.
