Currently, the large amount of waste produced is a significant problem for the environment and for the people who live near the deposits of by-products obtained from technological processes. Limited storage capacity, as well as the uncontrolled disposal of waste or industrial by-products from landfills, are growing concerns for environmental protection. The recovery of waste can be carried out to obtain new inorganic materials, known under several names, including geopolymers, alkaline activated materials. Aluminosilicate sources can come from industrial by-products such as silica fume, slag, fly ash, etc. In the formulation of this material, the type, ratios and concentrations of the compounds in the mixture are very important to the properties of the new inorganic materials. Prior to synthesis, a compressive analysis of the source materials must be performed to identify the minerals present and their amount relative to the total mass. The aim of this study is the formulation and characterization of new alkaline activated materials with the replacement of cement and establishing the influence of the properties of raw materials over final products.
