Aggregate size and shape vary, too. The size, which can range anywhere from 3/8 inch to 2 inches or more in diameter, largely determines the depth of exposure. Aggregate shape affects the surface pattern and texture. Rounded aggregates provide the best coverage and a smoother surface while angular aggregates add more texture and dimension.

Sand is broken down into two different types: fine and coarse. Fine sand is used as a filler and bulking material in construction due to its small size and ability to be packed tightly. This allows it to fill in the empty spaces other construction aggregates like gravel can't. Coarse sand is used as a primary component in concrete mixtures.
