Concrete Aggregate (3/8″ To 1/2″, Astm, Coarse, Blue)

Concrete Aggregate, ASTM Coarse, 3/8” to 1/2”, Blue

Concrete aggregate in the 3/8” to 1/2” size range, meeting ASTM coarse specifications, is a high-quality material commonly used in structural concrete mixes. This aggregate is typically produced by crushing and screening durable stone, resulting in angular, blue-hued particles that provide excellent interlock and strength within concrete.

The 3/8” to 1/2” size is ideal for achieving a strong, stable matrix in concrete, ensuring optimal compaction and reducing voids. Its coarse grading enhances load-bearing capacity and minimizes shrinkage, making it suitable for foundations, slabs, driveways, and commercial flooring. The ASTM certification guarantees consistent quality and performance, while the blue color can add a subtle decorative touch to exposed aggregate finishes. This aggregate is less prone to dust and compaction issues compared to finer materials, but may not be suitable for thin overlays or applications requiring a very smooth surface.
