LIME
Lime is binding material used in construction industry. Lime is manufactured
from lime stone. A Cementing material may be defined as that material which
has capacity of holding structural unit together with sufficient strength.
MANUFACTURING
CALCINATION
Lime is produced in lime kilns, where limestone is heated until the
limestone is converted to quick lime(CaO) and carbon dioxide (CO2).
This thermal treatment of limestone is called calcination, and can be
described as CaCO3 → CaO + CO2.
It’s done at temperature of 900degree Celsius
CLASSIFCATION OF LIME
Classification of lime based on its composition
, i) Quicklime
ii) Hydrated lime
iii) Hydraulic lime
QUICK LIME
Quick lime is Amorphous (shapeless) white material. It has very high affinity
for water and carbon dioxide
USES
Large quantities of quicklime are used in various industrial neutralization
reactions. In steelmaking, quicklime is added to molten iron, where it reacts
with impurities in the iron to form slag, which can be easily removed, thus
helping to improve the purity of the steel.
HYDRATED LIME
Let’s begin with hydrated. When limestone is burned to produce lime it releases
CO2 gas. What remains is a highly alkali “quicklime.” Quicklime alternatively
known as “hot” lime is extremely reactive with water and can be dangerous to
handle, transport or work with although it has its construction uses for
experienced traditional masons and plasterers
