Influence of Mica on Compactability and Moisture …
Free mica was added to G5 gravel material in predetermined percentages of 0, 2, 5, 10 and 15% by mass so that subtle trends in effects of the mica content on the compactability and moisture content (absorption and retention) could be investigated. Figure 1 shows particle size distribution of free mica, neat gravel and the prepared specimens.
