When lime is mixed with water, lime slowly turns into the mineral portlandite (dense) in the reaction CaO + H 2 O = Ca (OH) 2. Lime is also less brittle and less prone to cracking, and any cracked areas can absorb carbon dioxide and mend over time. Country This can assist in controlling the temperature indoors and in preventing the growth of mould and mildew. The cement is obtained by burning a mixture of calcarious (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder. The high pH of lime acts as a fungicide preventing mold from growing in the lime plasters. This type of mortar is vulnerable to cracking and damage when exposed to heat or cold temperatures.
