Aggregate can be classified as fine or coarse aggregate. Fine aggregate is generally natural sand and is graded from particles 5mm in size down to the finest particles but excluding dust. Coarse aggregate is natural gravel or crushed stone usually larger than 5 mm and usually less than 16 mm in ordinary structure [1, 7, 9, 28, 29].
