WebAnswer (1 of 2): Angular sand is needed in applications such as stucco, mortar, and some plasters, where adhesion is important. This is because the edges of particles can grab surfaces. Also, angular particles have more surface area for a binder to stick to, and they are held more firmly in place... Rounding, roundness or angularity are terms used to describe the shape of the corners on a particle (or clast) of sediment. Such a particle may be a grain of sand, a pebble, cobble or boulder. Although roundness can be numerically quantified, for practical reasons geologists typically use a simple visual chart with up to six categories of roundness: • Very angular: corners sharp and jagged

Roundness (geology) - Wikipedia
WebGenerally, three grain categories are used in foundry sand: Rounded Grain sands provide relatively poor bonding strength, but good flowability and surface finish. Angular Grains have greater bonding strength because of interlocking, but poorer flowability and permeability than rounded grain sands. Sub-angular Grains are the middle road.
