10mm blue metal aggregate is a small-sized crushed stone sourced from basalt rock. This type of aggregate is perfect for concrete mixes, where its small size helps bind the mixture together while providing strength and durability. Its uses go beyond concrete, as it’s also used in landscaping for creating paths, garden beds, and drainage solutions. The uniform size of the stones ensures a consistent finish, while the natural blue-grey color of the basalt adds a decorative touch.
