Limestone and its Uses

The Main reason why limestone can be used are;-

  • To Build Buildings
  • Produce Glass, Cement, Concrete and Mortar

PROS

It provides Jobs for the People raising Local Economy

New products would continue to develop changing the way we live

CONS

Limestone is insoluble to water, However erode to Acid Rain caused by Sulpheric Acid

Limestone Quarries are a Eye-Sore and Produce Sound pollution

Products of Limestone

Limestone- Calcium Carbonate ( CaCO3)

QuickLime- Calium Oxide ( CaO)

Slaked Lime- Calcium Hyroxide (Ca(OH)2)

CaCO3 + Heat = Quicklime + Co2

Quicklime + Water = Slaked Lime + HEAT

Slaked Lime + More Water = Lime water


  • Lime water ------- IS USED TO SEE HOW MUCH CO2 is in the air
  • Quicklime + Water = Slaked Lime + Heat.
    • There is enough Heat to boil water hence alternate fuel source.

THERMAL DECOMPOSITION- Breaking down of a substance using HEAT.

E.G, CaCO3 + Heat = Quicklime.

Mortar and Glass

MORTAR

Slaked Lime + Sand + Water = Mortar

  • Used to plaster bricks together
  • Reaction occurs so the Lime reacts with Co2 to make Calcium Carbonate again.

GLASS

Powdered Limestone + Sand + Sodium Carbonate = Glass

  • Effective
  • Keeps heat in
  • Looks good
  • Transparent

Concrete and Cement

CONCRETE

Cement + Sand + Crushed Rocks + Water = Concrete

  • Strong
  • Good at resisting forces when squashed
  • Reinforced Concrete----When metal bars are used to make it Stronger

CEMENT

Limestone + Clay + Other Minerals = Cement

  • Unlike Mortar it sets underground
  • Made 200 years ago
  • Used all over the world
