· Newly delivered sand, in the early part of the day, will have more free moisture. After a rain the sand may briefly have even more than 6 percent coarse aggregate contains less free moisture and varies less. You may have as little as 1 pound of free moisture per 100 pounds of gravel or stone, and seldom more than 2 pounds (1/4 gallon).
