The mechanical reduction method (splitter) is especially appropriate for fine aggregates with free moisture.

• A. True
• B. Only for coarse aggregates
• C. Not used
• D. False

Answer: (D)

Splitters rely on even flow to produce representative halves, but fine aggregates with free moisture don’t flow cleanly. Water causes fines to cling and bridge, so the material can clog or stick to the splitter, leading to biased, uneven splits. Because of that, the mechanical reduction method is not especially appropriate for moist fines. It’s better to dry the material to remove free moisture or use an alternative reduction method that handles moisture more reliably.
