Manufacturing of lime comprises three stages, viz.:

It is available in quick or hydrated form. It is generally used as an undercoat and finishing coat of plaster.

The lime is produced by burning lime nodules (found in soils like black cotton soil containing silica) in the hydrated form. It can be used for masonry mortar.

This is also available in hydrated or quick form. It is used as the finishing coat in plastering and white washing.

This should be available in quick or hydrated form. It can be used as the finishing coat in plastering, white washing, etc. It is also used for masonry mortar with the addition of pozzolanic material (it is volcanic dust containing 80% clay with lime magnesia and iron oxide in varying proportions).

This is available as quick lime (lime obtained by calcining pure limestone) or as hydrated lime (dry power obtained by treating quick lime with water). The compressive strength of lime and mortar (1:3 by weight) should have 1.25 N/mm2 and 1.75 N/mm2 at 14 days and 28 days, respectively. This mortar is used for masonry work.

It is available in hydrated form. The compressive strength of lime sand mortar (1:3 by weight) should have 1.75 N/mm2 and 2.8 N/mm2 at 14 and 28 days, respectively. With such a strength they can be used for structural works such as arches, domes, etc.

This lime is also known as impure lime or lean lime. More than 30% of clay present in poor lime makes the lime to slack slowly. It sets and hardens very slowly and has very poor binding properties. It can form a thin paste with water. Because the lime is of inferior quality, it is…

It is the lime containing small quantities of silica, alumina and iron oxide, which are jointly in chemical composition with calcium oxide. Hydraulic lime can set and become hard even in the absence of CO2 and can set even under water. This is also known as water lime. Based on the percentage of clay, lime may…

It is the lime which has high calcium oxide content. This can set and become hard only in the presence of carbon dioxide. This is white in colour. This lime is also called high-calcium lime, pure lime, rich lime or white lime. It is mostly called fat lime as it slakes vigorously. By this process,…
