Calcined Clay—Limestone Cements: Hydration and Mechanical Properties of Ternary Blends
Through the study of binary and ternary blends, the work is focused on the influence of the substitution of the cement by calcined clay and/or limestone filler on the mechanical properties. Besides of an ordinary Portland cement, three binders were analyzed: one binary blend where 30% of the cement is replaced by calcined clay and two ternary blends—one with 15% of calcined clay and 15% of limestone filler and the other with 30% of calcined clay and 15% limestone filler. First, the results show that the substitution rate does not influence the overall degree of reaction determined with the cumulated heat evolution. Then, we notice that the behaviors of the 30% substitution blends (binary and ternary) are similar when the ternary blend with only 55% of Portland cement is clearly different. Finally, the mechanical properties brought back to substitution rate seem to be enhanced for the ternary blend with only 55% of Portland cement. This shows that the limestone filler allows to keep, and even to enhance, the mechanical properties of a binary blend by increasing the level of substitution.
