Why Is It Important As A Building Material?
Limestone is very popular in architecture. Limestone is readily available and it is relatively easy to cut in specific shapes or blocks or even for more extensive and elaborate carving in which there is precision design. It is also long-lasting and it is still tough even in exposure. Limestone used for construction is also good in humid and hot environments.
What Are The Drawbacks Of Using It In Buildings?
Limestone is an extremely heavy material and it is also very expensive to obtain. It is vulnerable to acids, so therefore it is highly susceptible in places where acid rain is a high occurrence. The acids in the rain are capable of wearing away the detail and the outline of the building or artwork, thus eroding the object up.
Why Is It Important As A Raw Material?
Limestone is also used in other fields of work. For example it is used in sugar refining. The lime in the limestone is used for the separation of impurities in the sugar. Limestone is also used in the making of iron in a blast furnace. The lime is used in the removal of sulphur in coal- fire power station gases. This is a way of preventing acid rain forming.
What Is The Difference Between Cement And Concrete?
Cement is an ingredient in concrete. It is the ingredient that forms a paste with the water, sand, and mixtures and fills the space between the coarse rocks and binds the rocks together. Cement is heated limestone, clay and sand which are then grinded together. Concrete is an artificial stone made by mixing cement and sand with gravel, broken stone, or other aggregate (rock).
Why Is It In The Making Of Glass?
Glass is made from sand and limestone. Limestone is added before the heating process in which the glass is formed. The limestone in the glass helps protect it from weathering. After the heating process which is done in cool conditions a soda-lime-silica glass product is formed, which is glass, as we know it. Glass is used in almost everything: glasses, windows, mirrors, computers etc.
What Are The Environmental Problems Associated With The Use Of It?
There are many environmental disadvantages which come with the use of limestone. For example, limestone quarries are large, and it could damage the local environment with its overshadowing and disfigurement of the local beauty. Quarrying is no quiet job. It creates heavy traffic and heavy noise. This completely ruins people’s way of life and their daily routine.
