GYPSUM LIME

Lime is a slow setting material; it takes a considerable time to gain rigidity. Setting time of lime is affected by: • the humidity and CO 2 content of the air (Setting time of lime is longer when the amount of moisture in the air is high and when the amount of carbon dioxide is low). • the amount of CaO present in lime.
