The surface texture of the aggregate plays a major role in determining the comprehensive strength. The fine aggregate can have a surface texture as both rough and smooth. The specific gravity is the ratio of the aggregate mass to the volume of water. This is primarily used for proportioning concrete mixtures and performing calculations.

SQL Aggregate Functions. An aggregate function is a function that performs a calculation on a set of values, and returns a single value. Aggregate functions are often used with the GROUP BY clause of the SELECT statement. The GROUP BY clause splits the result-set into groups of values and the aggregate function can be used to return a single value for each group.
