Limestone and Building Materials - C1
1 Rocks provide essential building materials
2 LIMESTONE
2.1 Naturally occurring resource
2.1.1 provides starting point for the manufacture of GLASS, CEMENT and CONCRETE
2.1.1.1 CEMENT
2.1.1.1.1 = LIMESTONE HEATED WITH CLAY
2.1.1.2 MORTAR
2.1.1.2.1 = CEMENT MIXED WITH SAND
2.1.1.3 CONCRETE
2.1.1.3.1 = MORTAR MIXED WITH SAND AND AGGREGATE
2.2 can be thermally decomposed to make new products
2.3 composed of the compound CALCIUM CARBONATE
2.3.1 CaCO3
2.3.2 is quarried and used as a building material
2.3.3 carbonates
2.3.3.1 magnesium, copper, zinc and calcium
2.3.3.1.1 ALL thermally decompose
3 CALCIUM OXIDE
3.1 reacts with water to produce
3.1.1 CALCIUM HYDROXIDE
3.1.1.1 an alkali
3.1.1.1.1 used to neutralise acid
3.1.1.2 A SOLUTION OF CALIUM HYDROXIDE IN WATER = LIMEWATER
3.1.1.2.1 reacts with CARBON DIOXIDE to produce CALCIUM CARBONATE
3.1.1.2.1.1 Ca(OH)2(aq) + CO2(g) ---> CaCo3(s) + H2O(I)
3.1.1.2.2 LIMEWATER is used to test for CARBON DIOXIDE
3.1.1.2.2.1 CARBON DIOXIDE turns limewater cloudy
3.1.2 CaO(s) + H2O(I) ---> Ca(OH)2(s)
4 CALCIUM CARBONATE AND ACID
4.1 carbonates react with acids to produce salt, carbon dioxide and water
4.2 limestone is damaged by ACID RAIN
