What Aggregate Packing is Optimal?

Aggregate packing is one of several factors to consider in selecting aggregates. Aggregate gradings finer than maximum packing density are often preferred. The packing density, along with shape, is useful in determining amount of paste required. Consider the combined solid particle size distribution.
