ASTM C33

ASTM C33 is a standard set by the American Society for Testing and Materials that specifies the requirements for concrete aggregate—essentially the materials mixed with cement to make concrete. This standard outlines the grading, quality, and properties of both coarse aggregates (like gravel and crushed stone) and fine aggregates (like sand), ensuring they are suitable for making durable and strong concrete. By following these guidelines, builders and engineers can ensure the safety, strength, and longevity of concrete structures, which are vital for roads, bridges, and buildings.
