Processes

Question 1

Concrete Reinforcement

Answer 1

It combines the high compressive strength of concrete with the high tensile strength of steel, as concrete has poor tensile strength.
Steel rebars are pre-stressed in the concrete and then cut to be compressed, thus strengthening the concrete

Question 2

Dry Corrosion

Answer 2

Also known as oxidation, occurs when a metal comes into direct contact and reacts to gases in the atmosphere, without the presence of moisture, which creates a layer of oxide on the surface of the metal

Question 3

Corrosive Environments

Answer 3

Areas where metals are exposed to conditions or substances where they may degrade and corrode

Question 4

Wet Corrosion

Answer 4

when a metal comes into contact with water which causes a corrosive chemical reaction to take place

Question 5

Corrosion Protection

Answer 5

Corrosion protection includes processes such as galvanisation and cathodic protection. Galvanisation covers the metal in a layer of zinc which protects the metal from corrosion, similarly with cathodic protection, zinc is a common material chosen as a sacrificial anode which corrodes itself to protect the metal from corrosion

Question 6

Life Cycle Assessment

Question 7

Life Cycle Assessment of Timber
