Shape and Texture. Shape and texture affect workability of fresh concrete. The ideal aggregate would be spherical and smooth allowing good mixing and decreasing interaction between particles. Natural sands are close to this shape. However, crushed stone is much more angular and requires more paste to coat the increased surface area.
