The criteria form the basis of segregation between the fine & coarse aggregate. Both types differ largely in properties and find their uses for different purposes. The general maximum coarse aggregate size used in cement concrete is 40mm, while 4.75-20mm is the most used size. For bituminous concrete, <10mm size aggregate is an apt choice.Web

An aggregate function performs a calculation on a set of values, and returns a single value. Except for COUNT (*), aggregate functions ignore null values. Aggregate functions are often used with the GROUP BY clause of the SELECT statement. All aggregate functions are deterministic. In other words, aggregate functions return the …Web
