SUMMARY:

LC³ (Limestone Calcined Clay Cement) mortars with different Portland cement contents (PC) (100%, 55%, 50%, 45%, and 40%) and a combination of metakaolin (MK) and limestone filler (LS) (0%, 45%, 50%, 55%, and 60%) in a 2:1 ratio were evaluated regarding their fresh, hygroscopic, mechanical, and thermal properties. LC³ mortars with as low as 40% Portland cement contents satisfied the normative requirements for applying on walls and ceilings. In addition, the incorporation of MK and LS for reducing PC consumption generated mortars with lower densities, reflecting in lighter materials with improved thermal insulation capacity with a reduction up to 4 ºC of the equilibrium plateau temperature for mortars LC³ – 55, LC³ – 50, LC³ - 45, and 2.5 ºC for the mortar with the lowest PC content (LC³ - 40).
