Limestone And Building Materials Flashcards
1
Q
What do you get when you decompose calcium carbonate by heat (thermal decomposition)?
A
You cogent calcium oxide and co2
2
Q
What happens when you react calcium oxide with water?
A
It produces calcium hydroxide, which is an alkali that can be used in the neutralisation of acids
3
Q
Who do you test for CO2?
A
It will turn limewater (calcium hydroxide and water) cloudy
4
Q
Carbonates react with acids to produce?
A
CO2, salt and water

How is mortar made?
A
Cement mixed with sand
8
Q
How is concrete made?
A
Cement with sand and aggregate
9
Q
What is limestone mainly composed of?
