Why buliding is called a building when it is alreafy bulid?
Answers
A building is called so a building because this exists for a long time because of the result of the act of those who built it . Because the suffix 'ing' is added to verbs to make noun forms . Building is a noun form of a thing that exists as the result of the act of those who built it.
Buildings are mostly built up of concrete. Concrete attains its maximum (but not full) strength after 28 days of curing (watering) but it takes more than 2 years for concrete to gain its full strength.
There is a continuous reaction between concrete and water which results in strength of concrete.Hope it helps
