For a measure of 14L [0.5 ft³], how many strokes of the taming rod are required for each layer?

To determine the number of strokes of the taming rod needed for a measure of 14 liters (or 0.5 cubic feet), it’s important to consider standard practices in concrete and soil compaction. The typical requirement is to ensure that the material is adequately compacted to eliminate voids and achieve the desired density.

For most materials, especially loose aggregates or soil, a common practice is to use around 25 strokes of the taming rod per layer to achieve proper compaction. This number is based on industry standards that help ensure sufficient densification and uniformity throughout the material being compacted.

Therefore, for a measure of 14L, the requirement of twenty-five strokes aligns with the established guideline, ensuring the material is properly compacted and prepared for further testing or usage in construction processes. This also supports achieving reliable results in tests that follow, as proper compaction is critical for accurate data collection and analysis.
