Ternary mixes composed of Portland clinker plus two different mineral additions emerge as an environmentally friendly alternative in the construction market.However, to significantly increase the sustainability of the designed mixes, very high mineral admixtures total contents must be used.Therefore, the substitution of Portland clinker by these high mineral admixtures contents can imply a decrease in the mechanical performance of the cementitious materials obtained, thus limiting their potential applications as their use in high strength concretes.Nevertheless, if the cement formulation is accurately designed by using adequate contents of each binder material and the chemical composition of the Portland cement (OPC) (or clinker) is appropriately selected, the obtaining of ternary mixes with mechanical properties similar or even improved than those obtained when using plain OPC (type CEM-I) materials can be achieved.Accordingly, in present work several ternary mixes were evaluated by combining OPCs with different chemical composition with Blast Furnace Slags (BFS) and/or Limestone Filler (LF) and/or Fly Ashes (FA).
