AB Limestone Calcined Clay Cements (LC3) are binders with complex phase development andmicrostructures. Although the hydration chemistry of these cements are being widely researched [1],due to the clay mineralogy variability, more studies are needed to build full knowledge. The use ofcalcined kaolinitic clays as SCMs in Portland cement is one of the best approaches, as metakaolinshows exceptional pozzolanic properties. Here, we report a summary of our ongoing research dealingwith LC3 binders based on Spanish calcined clays with different kaolinite content. The kaolinitecontents [2], jointly with the particle size of the calcined clays [3] will determine the reactivity, andconsequently, the mechanical performances. Initially, a selection of three commercially availableSpanish kaolinitic clays was carried out. Mineralogical and elemental analyses were obtained by Xraypowder diffraction (XRPD) and X-ray fluorescence (XRF), respectively, are elsewhere [3]. The clayprovenance and estimated average kaolinite contents are given in Table 1; the latter was obtainedthrough the combination of three methodologies (LXRPD, thermal analysis and XRF) [3].
