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 dimensionTypes of aggregates used in concrete include crushed stone manufactured sand gravel natural sand and recycled concrete Different Types of Aggregates Used in Concrete CEMEX USA removing and crushing existing concrete to a preferred size It is commonly used as a base layer for other construction materials because it compacts to
