3/8 Aggregate (Crushed Stone)

Overview:

3/8 aggregate, also known as crushed stone 3/8, is a finely graded type of gravel commonly used in construction, concrete production, and landscaping. Its small particle size makes it ideal for enhancing the strength and durability of concrete mixes, as well as providing a smooth finish for various applications.
