4 Types of Limes

1.Quick lime

It is also known as caustic lime. It is obtained by calcination (i.e. heating to redness) of comparatively pure lime stone. It is amorphous in nature, highly caustic and possesses great affinity to moisture.

2.Slaked lime

It is also known as hydrate of lime. It is obtained by slaking (i.e. chemical combination of quick lime with water) of quick lime. It is ordinary pure lime, in white powder form, available in market. It has got the tendency of absorbing carbonic acid from the atmosphere in presence of water.

3.Fat lime

It is also known as high calcium lime or pure lime or rich lime or white lime. It is popularly known as fat lime as it slakes vigorously and its volume is increased to about 2 to 2.5 times that of quick lime. This lime is used for various purposes as white washing, plastering of walls, as lime mortar with sand for pointing in masonry work, as a lime mortar with surkhi for thick masonry walls, foundations, etc.

4.Hydraulic lime

It is also known as water lime. This lime contains clay and some amount of ferrous oxide. It sets under water and hence also known as water lime. Depending upon the percentage of clay IS has divided hydraulic lime in three classes namely:

• A级 - 液压液体
• Class B – Semi Hydraulic
• C类——不n-hydraulic (or Fat lime)

A级 - 液压液体

该石灰含有约25％的粘土含量，并在一天新利18体育官网登录左右的果蝇中容易地设置。这款石灰难以释放。由该石灰制备的砂浆和石灰混凝土对于在水下或潮湿地点的施工非常有用。

Class B – Semi Hydraulic

Semi-hydraulic lime contains about 15% clay content and sets under water at a slower rate within a week or so. The mortar and concrete prepared from this lime is strong and used for superior type of masonry work.

C类——不n-hydraulic (or Fat lime)

This lime contains about 7.5% of clay content and is prepared from pure lime stone. This slakes vigorously within few minutes but does not set under water. This is used for white washing and colour washing.
