Abstract
Shaped particles having a longitudinal length (L) and a predetermined complex cross-sectional shape extending on a plane perpendicular to said longitudinal length (L). The cross-sectional shape has at least one vertex. An edge extends along the length L from the vertex. The particles further comprise an anchoring element disposed away from the edge. The ratio of said length (L) to a perimeter-equivalent diameter of said predetermined cross-sectional shape “ECD PHull” is between about 0.5 and about 5.
