An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O.

Lime Mortar Tips

Mortar Mixing. Lime mortar does not require water to grow crystals, cure and get hard like cement based mortars. Limes get hard by absorbing carbon dioxide from the atmosphere. As such, you must add only just enough water to make the mortar workable. Mortar can be mixed by hand or in a modern cement mixer.

Lime Production from Limestone

In this process, only one mole of gas is formed, so the net of the moles increase in the formation of lime since there are no gaseous products, therefore by decreasing the pressure, it will favor the production of more carbon dioxide molecules, ultimately shifting towards the right (products) side and producing more lime.
