| 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 buildings. It is
used for washing the rooms, stabilizing the soils
and knotting of timber works before painting. Quick lime is the calcined material, the major part of which is calcium oxide. It also contains relatively smaller amount of magnesium oxide and is capable of slating with water. Fat lime is 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 a lime containing small quantities of silica and alumina and/or iron oxide which are in chemical combinations with some of the calcium oxide content. Hyderated lime is a dry powder resulting from the treatment of quick lime with water. | |
