The hydration behaviour of the lower-temperature standard quicklime is a lot more different than significant-temperature commercially developed quicklime, produced from the same stone. The lower temperature material hydrates far more gradually, reaches a decreased temperature and maintains a peak temperature plateau for longer when compared to the large-temperature quicklime. The traditional quicklime also generates around fifty% non-hydrated residue through the tests. This implies an origin for ?�lime inclusion??texture in historic mortars. Mortars created making use of regular hot mixing processes are petrographically much like historic mortars. The recognition of distinct quicklime microstructures might also supply a diagnostic Software for quality Handle in tiny-scale regular lime output.
