Miniature Stockpile Method
The miniature stockpile method is used for reducing all samples of fine aggregates when the material is in damp or moist condition. If the sample to be split is dry, the material is required to be moistened before using this method.
Procedure
- Place the original sample on a clean, dry plate or other hard, smooth, non-absorptive surface.
- Using a trowel or other suitable tool, turn the entire sample over three times.
- Shape the material into a conical pile.
- With a spoon or small trowel, randomly take at least five small portions of material around the pile and one-third way up the cone until the required sample is obtained.
