Gradation Of Aggregates | Types of Aggregate Grading

A dense gradation refers to a sample that is approximately of equal amounts of various sizes of aggregate. By having a dense gradation, most of the air voids between the materials are filled with particles. A dense gradation will result in an even curve on the gradation graph. Wide range of sizes. Grain-to-grain contact. Low void content.
