    Jul 24, 2016 a highly caustic material that is very "thirsty" for water. When combined with water – hydrated or "slaked" the quicklime becomes calcium hydroxide or Ca(OH)2, often simply referred to as "lime". This material quickly reabsorbs CO2 and once again becomes calcium carbonate, completing the lime cycle.

  • Cement Wikipedia

    This reaction takes a significant amount of time because the partial pressure of carbon dioxide in the air is low. The carbonation reaction requires the dry cement to be exposed to air, and for this reason the slaked lime is a nonhydraulic cement and cannot be used under water. This whole process is called the lime cycle.
