SOME INTERESTING FACTS ABOUT OUR PRODUCTS

Lime and Limestone are one of the basic materials without which life would be greatly diminished and modern commerce and industry could not exist. Literally, any object in man's home and his office has acquired these ancient, prosaic, unglamorous, low cost materials in some form of its manufacture directly or indirectly. In fact, the basic essentiality of Lime and Limestone has been linked to one leg of a six-legged stool on which industry revolves. The other essential legs being iron ore, salt, sulphur, petroleum and coal. Of these, Lime Stone is the greatest in physical volume.

BASIC DEFINITION : Lime and Limestone are much-abused terms, often users and even some sellers, refer to some form of Limestone as Lime and vice versa.

LIME : Lime is a general term that connotes only a burnt form of Lime, usually Quick Lime, but may also refer to Hydrated Lime. It does not apply to Limestone or any carbonate form of Lime.

QUICK LIME : Quick Lime is a lime oxide formed by calcining Limestone so that carbon di-oxide is liberated.

HYDRATED LIME : Hydrated Lime is a dry powder obtained by hydrating Quick Lime with enough water to satisfy its chemical affinity, forming a hydroxide due to its chemically combined water.
