21. Why do the construction companies provide more demand for aluminium ?
it of population ?
Answers
Recycling produces high-value economic impact. The production of secondary (recycled) aluminum saves more than 90 percent of the energy costs associated with primary production.

Answer:
Aluminium has ductile property and less corrosive in character are the major reasons to be used in construction fields.
Explanation:
Before 20th century, aluminium is not used in construction field because extraction of the aluminium is costly process. Since 20th century Aluminium is used in construction field when modern machines used in mining field.
Aluminium is the second most used metal after steel in construction fields. Aluminium is more ductile in character so it moulded and remoulded in different shapes so used in roof tops, wall panels and so on. Aluminium has less corrosive property than steel so it is used in humid conditions like bridges, swimming pools, hydraulic structures, etc.
