Characteristics of Aggregates: Shape, Size & Specific

Fine Aggregate Angularity measures the void content of an uncompacted specimen of fine aggregate, including sand, to provide an indirect indication of its angularity. A high void content indicates a higher degree of angularity, or surface roughness, of the particles. If the aggregate is too rounded, the shear strength of the matrix is reduced.
