Blends of sand sizes

Bunker sands have very little or no detectable organic matter. Bunker sand firmness is usually measured with a pocket penetrometer that has a golf ball affixed to the tip of the penetrometer. The details of the experiment that produced the results illustrated here can be found in this PACE Insights. What we observed was the ratio of 0.25 to 0.50 mm of a medium sphericity sand had a great influence on the penetrometer resistance compared to either the straight 0.25…
