The hydration behaviour with the lower-temperature common quicklime is more diversified than significant-temperature commercially created quicklime, produced from a similar stone. The reduced temperature materials hydrates more gradually, reaches a reduce temperature and maintains a peak temperature plateau for for a longer period when compared to the large-temperature quicklime. The normal quicklime also creates around 50% non-hydrated residue through the tests. This implies an origin for ?�lime inclusion??texture in historic mortars.
