Clay soils react well with calcium-based reagents like quicklime and Calciment LKD resulting in cation exchange and molecular flocculation and agglomeration within the soil. Cation exchange is a process where divalent calcium ions from quicklime or Calciment LKD replace monovalent ions that are present on the surface of clay particles.

Quicklime type is the most common production in Malaysia. Many lime producers in Malaysia are still using traditional port kilns which are able to produce between 30 t and 70 t of quicklime per unit. CO 2 emission from lime production in Malaysia is measured based on the common process in the production of quicklime [15].

At its core, the primary function of a lime kiln is to convert limestone (calcium carbonate) into quicklime (calcium oxide) through a process called calcination. This process is accomplished by subjecting limestone to high temperatures, usually between 900°C and 1100°C, within the kiln. The calcination process can be described in more detail ...

Lime – an interesting physical property. If a marble-sized piece of lime is heated to a high temperature, it emits a very bright white light. In the 1820s, British Army officer Thomas Drummond used this property of lime to develop a light that could be used in lighthouses and on the battlefield.

In the basic oxygen steelmaking (BOS) process, quicklime plays a crucial role. Quicklime and hydrated lime can significantly increase the load-carrying capacity of clay-containing soils by participating in chemical reactions with finely divided alumina and silica to create calcium silicates and aluminates, which have cementing properties.

In addition, storing quicklime can cause safety problems. If quicklime comes in contact with water, it begins to slake, a process which produces a great deal of heat and can cause explosions when uncontrolled. Quicklime should never be stored with alum since the quicklime will absorb water away from the alum and cause an explosion. Soda Ash
