For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.
The Gross Domestic Product (GDP) in Nigeria was worth 432.30 billion US dollars in 2020, according to official data from the World Bank. The GDP value of Nigeria represents 0.38 percent of the world economy.
