- Rocks and Building Materials
- Limestone and its uses:
- CaCO ---> CaO + CO
- Calcium Carbonate--> Calcium oxide + Carbon dioxide
- Thermal Decomposition
- CaCO ---> CaO + CO
- Reactions of Carbonates
- Metal carbonates decompose to the metal oxide and carbon dioxide when heated.
- acids+ Carbonates = salt, water and carbon dioxide
- Calcium hydroxide solution: Lime water
- The ' LIMESTONE REACTION CYCLE'
- CaCO - Ca0 + CO
- CaO + H O --> Ca ( OH)
- Calcium oxide + water ---> Calcium hydroxide solution.
- Calcium Carbonate --> Calcium Oxide + Carbon Dioxide
- CaO + H O --> Ca ( OH)
- CaCO - Ca0 + CO
- Cement and Concrete
- Cement : Limestone is mixed with clay and heated strongly
- Motar: Cement is mixed with sand and water
- Concrete: Add aggregate to cement , sand and water
- Arrigate: small stones or crushed rocks
- Limestone and its uses:
