  • Limestone
    • What is it?
      • Sedimentary rock
      • Calcium Carbonate
    • Uses
      • Building material
        • As a building material...
          • Eroded by acid rain
      • Making cement, mortar and concrete
    • As a building material...
      • Eroded by acid rain
    • Heating
      • When heated in a kiln it decomposes
        • Thermal decomposition
      • Calcium Carbonate -> Calcium Oxide + Carbon Dioxide
      • Calcium oxide reacts with water to make calcium hydroxide
        • Can be used to neutralise soils and lakes, and prevent crop failure
    • Cement, mortar and concrete
      • Powdered limestone with powdered clay in a rotary kiln makes dry cement
        • Add sand and water to make mortar
      • Add aggregate, sand and water to make concrete
