AbstractIn this work, authors report an investigation that reveals the possibility of dosing >Portland-Alkaline> hybrid cements by mixing small amounts of Clinker with different cementitious materials (in the form of binary mixtures, ternary, etc.). Specifically, one binary and three ternary cements are described in the paper: B2-FA [20% Clinker + 80% Flying Ash (FA)]; B3-FA [20% Clinker +50% FA + 30% Ground Granulated Blast Furnace Slag (GBBFS)]; B3-MK [20% Clinker + 40% Blast Furnace Slag (BFS) + 40% Metakaolin]; B3-BT [20% Clinker + 40% Blast Furnace Slag (BFS) + 40% Dehydroxylated Bentonite]. These cements (in the absence and presence of a solid activator) have been hydrated with water. All of them have the same Clinker content (20%) and all of them have technological properties (mechanical strength development) similar or even better than the commercial cements used as reference. Finally, and the most relevant is that all of them, in their hydration process, there is a generation of more than one type of cementitious gel.
