Web7.9 The lime cycle. The lime cycle is one of the most important in construction materials, and also one of the oldest chemical processes used on a large scale. The Romans produced lime in large quantities. The first process is calcination of limestone, by heating to a high temperature. This is carried out in kilns. WebLimewater. Limewater is the common name for a saturated aqueous solution of calcium hydroxide. Calcium hydroxide, Ca (OH) 2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C [1] ). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste.
