These methods verify that the concrete aggregates comply with ASTM C33 specifications. This ensures the durability, strength, and overall performance of the finished product. Contractors, suppliers, and inspectors ensure aggregates used in concrete meet performance and durability criteria by conducting these tests.
Important Aggregate Dos and Don'ts. DO use aggregate that's in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." Aggregates must be sound, clean, hard, durable, and free of excessive fines or contaminates that can affect cement hydration or disrupt the paste-aggregate bond.
