1 of 17
How is concrete made?
Mixing cement with sand, aggregate and water
2 of 17
What compound is mainly found in Limestone?
Calcium Carbonate CaCO3
3 of 17
What does calcium carbonate decompose to?
Calcium oxide and carbon dioxide
4 of 17
What is the the type of reaction called when limestone is broken down?
Thermal Decomposition
5 of 17
How is calcium carbonate broken down?
IT is down on a large scale using a lime kiln
6 of 17
What do metal carbonated decompose to?
The metal oxide and carbon dioxide when heated strongly enough.
7 of 17
What are the products when zinc carbonate is heated strongly?
Zinc oxide and carbon dioxide.
8 of 17
What do carbonated produce when they react with acid?
Salt, water and carbon dioxide gas.
9 of 17
What is lime water?
Carbon hydroxide solution.
10 of 17
What happens when lime water reacts with carbon dioxide?
It turns cloudy because it reacts with carbon dioxide to form insoluble calcium carbonate.

Describe the 'limestone reaction cycle'
1. Calcium carbonate is heated to give off CO2 and CaO 2. CaO + H2O -> Ca(OH)2 3. Add more water to make calcium hydroxide solution 4. Add CO2 to solution to make calcium carbonate

How is Cement made?
Limestone is mixed with clay and is heated very strongly in a kiln. The product is ground up to make a fine powder.
13 of 17
How is mortar made and what is its used?
Cement is mixed with sand and water. Mortar is used to hold bricks and blocks in buildings.
14 of 17
What is aggregate?
Crush rock
15 of 17
What is a negative impact of quarrying limetsone?
Destroys environment and effects peple locally in a negative way.
16 of 17
What is the problem with cement works?
The heating o limestone and clay requires large amount of energy. The works also need a lot of space.
