Lime

Lime 
         Several historical monuments are the evidence of durability of lime mortars. Lime is obtained by burning any form of lime stone over 900° C. Lime is used for plastering interior surfaces of walls , preparing concrete for Foundation and flooring of ordinary building . It is used for washing the rooms , stabilizing the soils and knotting of timber works before painting.

Quick lime 
                   It is the calcined material, the major part of which is calcium oxide in natural association with a relative smaller amount of magnesim oxide and capable of slaking with water

Fat lime 
                The lime which has high calcium oxide content and is dependent for setting and hardening solely on the absorption of carbon dioxide from the atmosphere.

Hydraulic lime
                             Is is lime containing small quantities of silica and alumina and / or iron oxide which are in chemical combination with some of the calcium oxide content, giving a putty or mortar which has a property of setting and hardening under water

Hydrated lime 
                          Is is dry powder resulting from the treatment of quick lime with water , enough to satisfy it's chemical affinity for water under the conditions of its hydration.

Lump lime

•                     Quick lime as it comes from the kiln is called lump lime.
