ASTM C-33 (Aggregates for Concrete)

ASTM C-33 is a standard guideline that specifies the requirements for aggregates used in concrete. Aggregates include materials like sand, gravel, and crushed stone. This standard ensures that these materials meet quality, size, cleanliness, and strength criteria to produce durable, safe, and high-quality concrete structures. It covers how aggregates should be tested, classified, and distributed to ensure consistency across construction projects. Essentially, ASTM C-33 helps builders select and use appropriate materials so that concrete performs reliably over time.
