    Aggregate Gradation Matters| Concrete Construction Magazine

     · Most specifiions require coarse and fine aggregate to conform to the requirements, including the gradation, of ASTM C33. Concrete producers then use that material to make concrete, the properties of which are quite dependent on the aggregate gradation, both coarse and fine. This presents a conflict — if the aggregate gradation changes, then the concrete proportions may need to be .

    What is a Concrete Aggregate? (with pictures)

    Using aggregate makes concrete much stronger, with the aggregate acting as a type of reinforcement. The aggregate increases the lifetime of the concrete, and makes it more durable. Contractors can choose from fine aggregates, made from small particles of material, and coarse aggregates, which are made with large chunks. Companies which produce concrete aggregate usually grade their products .
