Lime is the one of most important and largely used building material.
Lime has been used as main cementing material until the invention of Portland cement.
Egyptians and Romans have made remarkable application of lime in various construction purpose.
Even in India, various engineering structures such as big palaces, bridges, temples, forts and monuments were constructed using lime as cementing material.
The usage of this structure is due to better workability, early stiffening, good strength, excellent adherence and resistance to moisture.
Even though lime is replaced by cement widely, lime is still used in many works.
Sources of lime:
Generally, lime is not available in nature.
It is formed by burning of limestone.
Depending on a percentage of calcium carbonate (CaCO3) in limestone, lime obtained is classified into A, B and C types.
The A type lime is available in a slaked form and is used for masonry works.
The B type lime is available in a slaked and unslaked form and is used for mortar and plaster works.
The C type lime is available in a slaked and unslaked form and is used for white washing works.
Lime is also obtained by burning kankar, shells of sea animals etc.
The lime obtained from calcination of pure limestone is known as quicklime.
It generally consists of oxides of calcium and it is not crystalline.
It shows great affinity to moisture.
