Limestone and Building Materials - C1
- Rocks provide
essential building
materials
- LIMESTONE
- Naturally occurring resource
- provides starting point for the
manufacture of GLASS,
CEMENT and CONCRETE
- CEMENT
- = LIMESTONE HEATED WITH CLAY
- = LIMESTONE HEATED WITH CLAY
- MORTAR
- = CEMENT MIXED WITH SAND
- = CEMENT MIXED WITH SAND
- CONCRETE
- = MORTAR MIXED WITH SAND AND AGGREGATE
- = MORTAR MIXED WITH SAND AND AGGREGATE
- CEMENT
- provides starting point for the
manufacture of GLASS,
CEMENT and CONCRETE
- can be thermally
decomposed to
make new products
- composed of the compound
CALCIUM CARBONATE
- CaCO3
- is quarried and used
as a building material
- carbonates
- magnesium, copper,
zinc and calcium
- ALL thermally
decompose
- ALL thermally
decompose
- magnesium, copper,
zinc and calcium
- CaCO3
- Naturally occurring resource
- CALCIUM OXIDE
- reacts with water to produce
- CALCIUM HYDROXIDE
- an alkali
- used to neutralise acid
- used to neutralise acid
- A SOLUTION OF CALIUM
HYDROXIDE IN WATER =
LIMEWATER
- reacts with CARBON DIOXIDE to
produce CALCIUM CARBONATE
- Ca(OH)2(aq) + CO2(g) ---> CaCo3(s) + H2O(I)
- Ca(OH)2(aq) + CO2(g) ---> CaCo3(s) + H2O(I)
- LIMEWATER is used to test
for CARBON DIOXIDE
- CARBON DIOXIDE turns limewater cloudy
- CARBON DIOXIDE turns limewater cloudy
- reacts with CARBON DIOXIDE to
produce CALCIUM CARBONATE
- an alkali
- CaO(s) + H2O(I) ---> Ca(OH)2(s)
- CALCIUM HYDROXIDE
- reacts with water to produce
- CALCIUM CARBONATE AND ACID
- carbonates react with acids to
produce salt, carbon dioxide and water
- limestone is damaged by ACID RAIN
- carbonates react with acids to
produce salt, carbon dioxide and water
