At Arcosa Lightweight, we are committed to delivering expanded shale and clay lightweight aggregates that consistently exceed industry standards for quality and performance. Each of our production facilities operates under a rigorous quality control plan, ensuring every yard of lightweight aggregate meets strict specifications for unit weight, gradation, and overall consistency.
Our quality control systems are harmonized across all our plants, allowing us to maintain consistent product quality while accounting for the unique characteristics of each facility’s aggregate. This ensures that whether your material comes from one plant or another, you receive the same reliable performance every time.
Our aggregates are produced to meet and often surpass the requirements of ASTM C330 for Structural Lightweight Concrete and ASTM C331 for Concrete Masonry Units. By continuously monitoring and adjusting our processes, we not only meet but exceed these standards, providing our customers with materials they can trust for their most demanding projects.
