Three test-specimens were moulded for each one of the mixtures. They were kept in the mould during the first seven days at laboratory conditions of 20 °C of temperature and 60% of relative humidity. Afterwards, they were removed and kept in the same conditions up to 60 days for curing time. After this period, samples were flattened by means of mechanical polishing of the surface in order to have flat and parallel sides. Subsequently, the samples were returned to laboratory conditions for up to 90 days of curing time in order to guarantee the stabilization of the carbonation-setting process, as well as their mineralogical composition, which would determine the properties and make them reliable. In addition, an extended curing time limited the amount of water in the mortar and its influence in the bulk density and thermal conductivity [32], [53], [58], [59], [60] and [61]. Regarding this, differences on the results were compared to those of other authors who performed the tests on lime mortars for a shorter curing time [10] and [62].
