Classification of Lime as a Building Material for use in Construction as per IS 712-1973 is as Follows:
1. The Class A lime are the hydraulic lime, that undergoes setting under the action of water. These are used for the construction of structures like arches and domes.
2. Class B is semi-hydraulic in nature. They are limited to small area work, like in masonry constructions.
3. Class C are called as fat lime. Another name for the same is quick lime or white lime or non-hydraulic lime. These are used for works like whitewashing, as a final coat for plastering etc. It is also used in the making of masonry mortar with the help of an additional pozzolanic material.
4. Class D is categorized for lime that is of magnesia or dolomite origin. For finishing works of plastering and white washing, the class D lime can be used
5. Kankar lime is the lime that is categorized under the class E. This lime is produced by the burning of lime nodules that are mainly found in the black soils, that constitutes silica. This forms to be hydraulic in nature. The main application of Kankar lime is in masonry mortar.
6. The siliceous dolomite lime is grouped under the class F lime. This is mainly used in the finishing coat of plaster or for its undercoat.

Classification of Fat Lime
Fat lime is a type of lime that falls under Class C in lime classification. This classification is based on the amount of clay impurities present in the lime. Fat lime is also known as high calcium lime or pure lime.
I. Classification of Lime:
Lime is classified into four classes - Class A, Class B, Class C, and Class D. These classes are determined based on the impurities present in the lime. The classification helps in selecting the appropriate type of lime for various construction applications.
II. Class C Lime:
Class C lime, also known as fat lime, contains a relatively high amount of clay impurities. It is characterized by its fat or greasy texture and its ability to set slowly. Class C lime is obtained from limestone that contains a significant amount of clay.
III. Properties of Fat Lime:
1. Composition: Fat lime is composed mainly of calcium oxide (CaO) along with small amounts of magnesium oxide (MgO) and other impurities.
2. Color: It is usually white or gray in color.
3. Reactivity: Fat lime has low reactivity with water, which results in slow setting and hardening.
4. Plasticity: It exhibits good plasticity due to the presence of clay impurities.
5. Strength: Fat lime has low strength and is not suitable for load-bearing structures.
IV. Uses of Fat Lime:
1. Mortar: Fat lime is commonly used in the preparation of mortar for masonry works. It provides good workability and plasticity to the mortar.
2. Plastering: It is also used in plastering works to create a smooth and even surface.
3. Whitewashing: Fat lime is a traditional material used for whitewashing walls and ceilings.
4. Lime Putty: It can be used to prepare lime putty, which is used in various applications such as repairing old buildings and making lime wash.
5. Soil Stabilization: Fat lime can be used in soil stabilization to improve the engineering properties of clayey soils.
In conclusion, fat lime falls under Class C in lime classification. It is characterized by its high clay content, slow setting, and low strength. Fat lime is commonly used in mortar, plastering, whitewashing, and soil stabilization applications.
Fat lime is a type of lime that falls under Class C in lime classification. This classification is based on the amount of clay impurities present in the lime. Fat lime is also known as high calcium lime or pure lime.
