Which dumping pattern provides the easiest blending of two materials that do not mix easily, such as clay and sand?

• A. Dumping and spreading a layer of one material, and then the same for the other
• B. Layering both materials at once
• C. Dumping in alternating small piles
• D. Dumping the heavier material first and then the lighter material

Answer: (A)

Blending two materials that don’t mix easily works best by building the mix in layers. Dump a layer of one material and spread it evenly, then dump and spread a layer of the other material. Repeating this layering and spreading lets the materials interlock at many interfaces as you move across the area, producing a more uniform blend than trying to mix everything in one go. This approach reduces the tendency for the materials to segregate by density or particle size, which can happen if you dump them together all at once, in alternating small piles, or in a single heavy-then-light sequence. By adding in layers, you create consistent contact between the materials and control the placement, leading to a smoother, more homogeneous fill.
